The coagulation parameters must also be controlled medications 1 gram purchase generic mentat ds syrup line, particularly fibrinogen concentration medications vs grapefruit order mentat ds syrup 100ml free shipping. In the case of any relevant alteration in the coagulation parameters symptoms dengue fever order 100ml mentat ds syrup overnight delivery, replacement must be suspended and no further sessions will be carried out until the parameters return to adequate levels (see sections 5 medications xanax order mentat ds syrup 100 ml line. The control group will undergo simulated (sham) low volume plasma exchange which will last approximately the same time as the subjects in the treatment group treatment 02 buy mentat ds syrup 100 ml low cost. Due to the difference in volume (removed/infused) symptoms your having a girl buy generic mentat ds syrup 100ml, it is advised to infuse saline solution to avoid the risk of hypotension related events (see Appendix 10 for guidance). The main characteristics of the product can be found in the Full Prescribing Information (Appendix 1). No remaining product in an opened container can be stored in the refrigerator and used at a later time. At the discretion of the investigator, patients can be premedicated with paracetamol and antihistamines. Replacement is to be postponed 24 hours if fibrinogen <1 g/L or the prothrombin time (Quick) <60% of the control value. Relevant alterations of coagulation parameters are not expected to occur with the low-volume plasma exchanges (Maintenance period). If a patient presents an adverse event two times with the same infusion rate, the following doses will be administered at the maximum tolerated rate. In any case, and considering the special vulnerability of the patients studied, a number of precautions (in addition to the habitual measures) have been taken to minimize the risks of the procedure: 1. Plasma exchange will be carried out by specialized nursing personnel, under direct and continuous supervision by the specialists. Subjects will be required to remain in the center before and after the procedure for longer periods of time than usual. Vital signs and laboratory test parameters will be monitored more frequently than usual. The person accompanying the subject should be present and/or in proximity before, during and after the procedure but not in the same room in order to maintain the blind. In this case it is mandatory the subject is scheduled for the treatment a different day than the rest of the patients. The patient will have direct, 24-hour access to the specialist (by mobile phone) in both the replacement phase and during subsequent follow-up. In fact, the plasmaphereses performed within this period will be very similar to those performed for regular plasma donations. For special warnings and precautions see the corresponding Full Prescribing Information (Appendix 1 and 2). When volume replacement is performed with 5% albumin, the risk of hypocalcemia is considerably lower than when plasma is used for replacement (seen historically in approximately 7. The factors predisposing to hypocalcemia may be patient-related (hypoalbuminemia, vitamin D deficiency (malnutrition, malabsorption), hypomagnesemia, hyperphosphatemia, altered liver or kidney function or hypoparathyroidism) or related to the procedure (duration of citrate infusion >120 minutes, respiratory alkalosis generally induced by tachypnea). All plasma exchanges produce transient hypocalcemia that is usually well tolerated by the patient. Occasionally, the decrease in ionic calcium levels can increase nerve cell membrane excitability, resulting in symptoms. The calcium chloride formulation must be infused diluted in physiological saline solution, at a maximum concentration of 2 mg/mL. If the patient shows Level 2 symptoms from the start or before the first 120 minutes of replacement, prophylactic blood calcium treatment should be provided. The predisposing factors may be patient-related (low body weight, a history of vasovagal reactions, or a low hematocrit) or related to the procedure (equipment fatigue or extracorporeal volume >20% of patient volemia). Recommendations for preventing hypotension related events in low-volume plasma exchange procedures have been captured in a study guideline. Hypotension episodes can be avoided by infusing saline solution and adjusting the removed plasma volume in low-weight patients (see Appendix 10). As a recommendation, mild allergic reactions could be controlled with antihistamines (diphenhydramine 25-50 mg i. In case the reaction continues, or in the event of anaphylactic manifestations, it could be administered 0. During daily plasma exchange sessions the fibrinogen concentration may drop to below 1 g/L, requiring the infusion of plasma or fibrinogen. Minor bleeding associated with severe thrombopenia has been observed (seen historically in approximately 2. As to the adverse effects if the catheter is placed in the subclavian vein, the risk of infection is minimal. Thus, while the incidence of infections with all the catheters is <5 per 1000 days (<3% of all catheters), this incidence decreases considerably if only those placed in the 23,24 subclavian vein are considered. Pneumothorax, hemothorax, bleeding at the time of placement and thrombosis in the case of indwelling catheters left in place for extended periods of time may be seen. The recommendations for the treatment and prevention of fever management and thromboembolic events have been captured in two study guidelines (see Appendix 11 and Appendix 12, respectively); nonetheless the sites should follow their local procedures. As to adverse events related to peripheral access, the most commonly expected are: pain, phlebitis, infiltration and extravasation. There are some sites that include corticosteroids administration during immunoglobulin infusion. Principal Investigator may consider changing the medication to other antihypertensive drug at the screening visit and maintaining throughout the study. The investigator (or pharmacist) or designated team member is to keep all records of drug utilization. The sponsor will provide specific forms to be completed by the investigator, pharmacist or designated team member, at the time of dispensation. These forms can be replaced by proprietary forms of the study center, provided they meet the requirements of the sponsor. Once the forms have been completed, they must be signed and dated by the monitor and by the investigator to confirm their accuracy. It must not be frozen and the unused contents of the vial should be kept separately until drug accountability has been completed. Solutions with evidence of turbidity should not be used because of the risk of bacterial contamination. The principal investigator is responsible for follow-up of the medical needs of the subject. During the treatment phase, the physician supervising the plasma exchanges will propose the adequate measures according to the condition of the subject. Since it has been suggested that systemic infections can have a detrimental effect on cognitive scores, monitoring of subjects for number and type of bacterial infections requiring antibiotics will be performed. Vital signs (blood pressure, heart rate, respiration rate, and body temperature) will be recorded before, during and after each plasma exchange session, where required. According to the criterion of the investigator, all the clinically important changes in vital function, laboratory test parameters and neuroimaging findings will be evaluated. However, on subsequent visits, recording will be limited to the abnormal conditions observed during the previous visit, along with the concomitant medication and any adverse event that may have been detected. Sufficient blood will be collected for all the laboratory tests, and a plasma sample will be stored at -70 C for any possible future analysis. In addition, a blood cell count will be performed, including: hematocrit, hemoglobin and erythrocytes, platelets and leukocytes (if an abnormal leukocyte count is recorded, it will be obligate to specify neutrophils, basophils, eosinophils, lymphocytes and monocytes). All the inclusion criteria are to be confirmed again after obtaining the laboratory test results. If the inclusion criteria are not met, or if some exclusion criterion proves applicable, the patient may not be entered into the study. If the subject is to receive full plasma exchanges through a central venous access, a double lumen catheter will be placed in the subclavian or jugular vein before the full plasma exchange period. It is advisable to place the catheter a few days before the first plasma exchange session. If these procedures are not carried out in the days preceding plasma exchange, they will have to be done on the day of first plasma exchange with the subject remaining at rest until indication by the investigator that plasma exchange can be carried out. A maximum of six full plasma exchange sessions will be made during this period: one per week. The subject will remain in the center throughout the procedure and then for as long as needed to ensure a safe return home, under conditions similar to before plasma exchange. Before plasma exchange, a physical examination will be made, with the recording of any anomalies. The anxiety and restlessness tests, if necessary, will be performed before each plasma exchange process, and between 15-30 minutes after replacement. Vital signs (axillary temperature, heart and respiration rate, and blood pressure) will be determined 15-30 minutes before replacement during and again 15-30 minutes after the procedure, and as often as considered opportune by the investigator. Control group the control group will undergo simulated (sham) full plasma exchanges and will follow the same schedule of assessments including the lumbar puncture. Additional plasma samples will be collected each time for storage at -70 C and possible future assays. During the visit medical history will be checked with the recording of any anomalies. Concomitant medication is also to be registered, together with any adverse event detected since the last visit or since the last plasma exchange session. The plasma samples of the patient will be collected before and 15-30 minutes after each procedure, to allow the pertinent tests. These plasma samples collected before and after the procedure will be stored at -70 C for possible future assays. In addition, a cell count will be made including hematocrit, hemoglobin and erythrocytes, platelets and leukocytes (if an abnormal leukocyte count is recorded, it will be obligate to specify neutrophils, basophils, eosinophils, lymphocytes and monocytes). A more intense monitoring is not considered mandatory since in this period the procedure is similar to a plasma donation plasmapheresis. However, the investigator can decide to assess other parameters for safety reasons. The subject will remain in the center throughout the procedure and then for as long as needed to ensure a safe return home, under conditions similar to before the procedure. Before each plasmapheresis, a physical examination will be made, with the recording of any anomalies. Control group the control group will undergo simulated (sham) low-volume plasma exchanges but will follow the same schedule of assessments. Plasma samples will be collected from the subjects (control and treatment group) to allow the pertinent tests. In case the final visit is conducted before completing the study, some assessments could be avoided. It will be decided case by case and depending on when the last assessments have been done. Physical examination likewise will be performed according to the practice of the investigator. The investigator will carry out a general evaluation of the body systems, together with a full physical examination during the initial visit and again at the end of follow-up. The vital signs will be measured according to standard practice of the investigator. Blood samples will be drawn according to standard practice of the center for the obtainment of blood, plasma and serum. The precise amount of each sample will be established according to the requirements of the specific laboratory performing the analysis. The sample will be divided into three aliquots: 3 mL for general tests (cell count, glucose, proteins and albumin), 3 mL for Aand P-tau (collected in polypropylene tubes), and 4 mL for o frozen back-up (-70 C), stored in cryopreservation tubes. The other two aliquots can be immediately frozen, however, future testing cannot be done if >10 erythrocytes are detected. In the event of insufficient blood or plasma sample volume, priority should center on the measurements of Aand P-tau, then reserving three mL for frozen back-up, and the rest for testing according to the course of the study and investigator criterion. During the visits, and after blood collection, processing of the samples to obtain the plasma and/or serum is to be made within two hours. The blood and plasma and/or serum samples will be collected and taken immediately to the site laboratory for processing. The serum and/or plasma samples can be analyzed on the same day (depending on the standard practice of the laboratory and test involved), or stored at -20 C for analysis within no more than two months after collection. Hematological, coagulation, and kidney and liver function tests will be performed by the standard practices of the laboratory. This test is widely used to assess cognitive alterations, and is the most commonly used brief screening test. The score ranges from 0 to 30, and is obtained by summing the points corresponding to each answer. The test performed on occasion of the selection visit will serve as criterion for inclusion in the study. The first part comprises 11 subtests that explore different areas: spoken language skills, test instructions recall, difficulty finding words, following instructions, naming objects, construction of figures, ideation praxis, orientation, recall and recognition of words.

The Indiana University project will provide coordinated care for Medicare beneficiaries with dementia or late-life depression and is projected to result in $15 symptoms 0f low sodium purchase 100 ml mentat ds syrup overnight delivery. Positive findings from any of these time-limited projects would not guarantee ongoing financial support my medicine mentat ds syrup 100ml low cost. Such findings could symptoms jaundice mentat ds syrup 100ml overnight delivery, however symptoms 7 days post iui buy cheapest mentat ds syrup, help to convince potential funders to pay for the treatments and care practices symptoms 9 days after iui cheap mentat ds syrup 100ml with visa. Ideally medicine 5000 increase buy mentat ds syrup 100 ml with mastercard, community agencies would offer an array of treatments and care practices to meet the diverse needs of people with these conditions, but agencies certainly cannot offer all of them. To decide which ones to offer, agencies will need to understand what the treatments and practices are, how they differ, where and by whom they are delivered, what they cost, and which people with which kinds of problems are likely to benefit from them. The research-based language of a classification system is clearly inappropriate for these people, however. The needed information will have to be presented in language they will understand. Participants in the June 2012 meeting noted that some of the terms that are currently being used probably create significant barriers to the wider acceptance and use of evidence-based non-pharmacological treatments and care practices. As noted at the beginning of this white paper, the meeting participants recommended against using the term interventions. They proposed two other terms, treatments and care practices, which have been used throughout the white paper. This term defines the treatments and care practices by what they are not, rather than by their intended positive effects. The term may also suggest to some people that medications (pharmacological treatments) and non-pharmacological treatments are mutually exclusive approaches to care. An alternate term, non-drug, might be better understood by some people but still defines the treatments and care practices by what they are not and fails to convey their positive effects. Still, participants in the June 2012 meeting emphasized that other mechanisms will also be needed to connect people to the right treatments and care practices for them. Most of the evidence-based treatments and care practices discussed in this white paper, and almost all of the multi-component treatments and care practices, begin with an assessment. In some of the existing treatments and care practices, the assessment is highly structured, and its findings lead directly to other components of the treatment or care practice that are intended to address the identified problems and care needs. In other treatments and care practices, assessment is less structured and functions more as a way of helping people with the conditions and family caregivers think about their situations and identify changes that would reduce problems and stress. In the latter treatments and care practices, assessment is ongoing and may be the core or most important component of the treatment or care practice. Between these two extremes, the existing treatments and care practices vary widely in the amount of emphasis they place on assessment and its specific purpose. The meeting participants agreed that assessment is a critical component of any mechanism to connect people to the right treatments and care practices, but they did not recommend particular characteristics of the assessment. People will not need this kind of help continuously but should be able to come back for additional help when their situations and needs change. Lastly, the meeting participants talked about where the mechanism should be based. It would also be available immediately after diagnosis, when it is certainly needed. Meeting participants who favored this option said that placing the mechanism in medical settings instead could result in overemphasis on medically related treatments and care practices and corresponding under-emphasis on non-medical treatments and care practices. They did agree that evaluating alternate mechanisms for connecting people to the right treatments and care practices at the right time is an important next step in expansion and sustainability of evidence-based treatments and care practices. Ongoing maintenance and regularly updated information about evidence-based treatments and care practices, translation study findings, and sources of financial support Participants in the June 2012 meeting noted that researchers, federal and state aging program administrators, health care and social service professionals, and other service providers would benefit from regularly updated information about evidence-based treatments and care practices, translation study findings, and sources of financial support. The meeting participants recommended that a government agency or private organization should be designated to serve these functions. Such an agency or organization might also convene forums for discussion among researchers, program administrators, health care and social service professionals, and other service providers about difficult issues that complicate the translation process and interfere with expansion and sustainability. Other such issues that arise most often when effective treatments and care practices are expanded into the community include who should own a treatment or care practice, who should maintain ongoing training and make decisions about modifications, and whether certification should be required for service providers who deliver the treatments and care practices. These evidence based treatments and care practices are not well known, and it is sometimes assumed that there are few, if any, such treatments and care practices. Gaps remain, and few of the existing evidence-based treatments and care practices are available at the community level. Still, the number of evidence-based non-pharmacological treatments and care practices is impressive, and additional treatments and care practices are currently being developed and evaluated. The meeting participants recommended research to develop, implement, and evaluate treatments and care practices for these subgroups. Other important topics for research are treatments and care practices to improve recognition and diagnosis of the conditions, effective ways to coordinate medical and non-medical care, and mechanisms to connect people to the treatments and care practices that are right for them. Exercise, cognitive training, and treatments that combine exercise and cognitive training are promising practices. The meeting participants emphasized the need for research to determine whether these treatments result in significant positive outcomes, especially for early-stage people. The current array of evidence-based treatments and care practices is difficult to understand and explain, primarily because there is no generally accepted classification system to categorize the types of treatments and care practices, the characteristics of people who benefit from them, and the kinds of problems they have been shown to reduce or resolve. Participants in the June 2012 meeting identified the development of such a classification system as a high priority next step for making evidence-based treatments and care practices available to people who need them. The language of a research-based classification system is unlikely to be understood or meaningful to most people who will make decisions about funding, providing, or using evidence-based treatments and care practices. Participants in the June 2012 meeting identified creation of this information as another high priority next step for making the treatments and care practices available to those who need them. Some findings from these translation studies have been published, but many of the studies are still underway or only recently completed. Findings from all these studies provide or will provide valuable information about which treatments and care practices can be delivered effectively by community agencies and result in the same positive outcomes that were found in the original research that established their efficacy. Researchers, program administrators, and community service providers who have led or participated in translation studies should be encouraged to publish their findings. Additional translation studies are needed to evaluate the feasibility and effectiveness of evidence based treatments and care practices that have not yet been tested in such studies. Findings from translation studies that have tested the same evidence-based treatment or care practice in multiple geographic localities are likely to be particularly helpful in understanding how the characteristics of localities, community agencies, and service providers may affect the delivery and outcomes of a treatment or care practice. The meeting participants recommended that resources should be provided to support analyses of these findings. A small but growing number of public and private organizations are providing financial support for delivery of some evidence-based treatments and care practices in a few communities across the country. Individuals are also paying out-of-pocket to use a few of the treatments and care practices. This is encouraging and suggests sources of financial support that might be accessed to make other evidence-based treatments and care practices available at the community level. The meeting participants noted, however, that it has taken a long time to obtain the current financial support, and there are substantial restrictions on eligibility for some of the funded treatments and care practices. At least one of the authorized programs could provide financial support for evidence-based treatments and care practices to help family caregivers. Other authorized programs will support time-limited research and demonstration projects rather than ongoing care and services. Participants in the June 2012 meeting pointed out that findings from such projects could provide new information about treatment efficacy, effectiveness, and/or cost-effectiveness that could increase the likelihood of longer-term financial support from other public and private organizations. They also recommended a comprehensive analysis of the health reform law to identify other programs that could support expansion and sustainability of evidence-based treatments and care practices. The meeting participants noted that these people should be included as often as possible in such projects, and project findings should be analyzed to determine whether the treatments and care practices worked for them. The steps described above will help to consolidate learning from already completed and ongoing research and translation studies.

Whitlatch, PhD Assistant Director Margaret Blenkner Research Institute Benjamin Rose Institute on Aging Nancy L. It has the unique and synergistic goals of teaching family caregivers behavioral strategies for reducing challenging care-related behaviors as well as increasing physical activity and functioning in their family member with dementia. Caregivers are taught behaviorally focused strategies for decreasing challenging behaviors characteristic of the disease process, such as depression, anxiety, agitation, and aggression, and taught methods to engage in and encourage physical activity and exercise in order to reduce the physical disability that often results in a loss of independence and a move to more restrictive and costly residential care settings. A structured treatment protocol provides detailed outlines and guidance for each session. Caregivers are taught how to encourage and help individuals with dementia with their exercises (including aerobic/endurance activities, strength training, and methods to improve balance and flexibility) by developing, implementing, and modifying, as needed, individualized behavioral plans. Caregivers are also taught to identify and modify care-recipient behavioral problems that can impair day to-day function, adversely affect caregiver/care-recipient interactions, and interfere with exercise participation. A comprehensive manual, as well as consultation regarding launching this program, is available. It is currently being implemented via an AoA grant to the state of Ohio with tremendous success. Preliminary outcome data are promising; providers and care-recipients report considerable satisfaction and eagerness to continue it in their home agencies as well as share their experiences with others, nationwide. Less well-funded but no less enthusiastic activities have been carried out in New Mexico, New York, and are planned for Minnesota. Challenges/Gaps in Knowledge and Future Directions As more states come on board and more agencies are engaged, two major rate limiting factors are worthy of discussion: 1. How to support continued program implementation and improvement as the initial grants supporting translational activity end, and who maintains ongoing training and program improvement As new agencies and ideas come to the fore, who funds this additional development In truth, it is the successful merging of both worlds but unfortunately, this means it with belongs to no one and funding remains a question. Sustainability of effective evidence-based programs is essential if we are to truly improve care. A myriad of external and internal factors can influence successful translation: agency directors change; staff turnover; reimbursement strategies alter the financial landscape. Agencies have experience with the former; we must all seek to find solutions to the latter. This project has just begun and while we are optimistic about the outcome, we are well aware that in order to maintain program stability and enable growth, these two issues will need to be addressed. Two programs were piloted, a dyadic support group (Memory Club) and a social engagement program (MeetUp & Mentor). Two workbooks were also published to address the needs of those who could not participate in more formal programming (Taking Action, Living Well). Dyads meet together for an educational session for the first part of the group (1 hour), then separate into peer groups for the remainder of the session (1 hour). Topics include common issues experienced by people living with early dementia (see Taking Action workbook). The program contains two components: social gatherings (online and in-person), and peer support (trained mentors call newly diagnosed people with early dementia, invite them to meet-up gatherings, and provide social support). MeetUp & Mentor: very small sample size, trends suggest increases in quality of life, emotional well-being, overall well-being, social satisfaction, and feeling supported. This multi-modal program includes a variety of evidence-based non-drug treatments, translating the science supporting the effects of enriched environments on neuronal functioning. Program components include cognitive training exercises, physical exercises (Tai Chi and Qi Gong), and creative/community involvement activities (writing, art, photography, etc. Methods of Delivery Program components are led by a multi-disciplinary team, with the Program Director being a PhD prepared researcher/clinician.

Psychological research has produced a great deal of knowledge about long-term memory rust treatment order mentat ds syrup 100 ml fast delivery, and this research can be useful as you try to learn and remember new material medications pictures 100 ml mentat ds syrup fast delivery. He discovered an important principle of memory: Memory decays rapidly at first medications elderly should not take purchase genuine mentat ds syrup line, but the amount of decay levels off with time (see Figure 5 medications help dog sleep night order mentat ds syrup with paypal. Bahrick (1984) found that students who took a Spanish language course forgot about one half of the vocabulary that they had learned within three years symptoms bipolar discount mentat ds syrup generic, but that after that time their memory remained pretty much constant medicine articles buy mentat ds syrup 100 ml lowest price. This suggests that Hermann Ebbinghaus found that memory for information you should try to review the material you drops off rapidly at first but then levels off after time. The spacing effect, also known as distributed practice, refers to improved learning when the same amount of studying is spread out over periods of time, then when it occurs closer together, known as massed practice. This means that you will learn more if you study a little bit every day throughout the semester than if you wait to cram at the last minute (see Figure 5. Ebbinghaus and other researchers have found that overlearning helps encoding (Driskell, Willis, & Copper, 1992). Students frequently think that they have already mastered the material, but then discover when they get to the exam that they have not. Try to keep studying and reviewing, even if you think you already know all the material. If you are having difficulty remembering the spacing effect refers to the fact that memory is better a particular piece of information, it never when it is distributed rather than massed. Leslie, Lee Ann, and Nora all studied for four hours total, but the students who hurts to try using a mnemonic or spread out their learning into smaller study sessions did better memory aid. These techniques are primarily used for simple memorization such as lists and names. Make use of self Material is better recalled if it is Connect new information about memory strategies reference.

Make use of the Information is learned better when Study a little bit every day; do not cram at the spacing effect it is studied in shorter periods last minute.

Go to this website to try some memory games illustrating key concepts in this chapter. Review the genetic basis for cognition and disorders at this interactive website. Imagine all of your thoughts as if they were physical entities, swirling rapidly inside your mind. How is it possible that the brain is able to move from one thought to the next in an organized, orderly fashion The brain is endlessly perceiving, processing, planning, organizing, and remembering; it is always active. Simply put, cognition is thinking, and it encompasses the processes associated with perception, knowledge, problem solving, judgment, language, and memory. Scientists who study cognition are searching for ways to understand how we integrate, organize, and utilize our conscious cognitive experiences without being aware of all of the unconscious work that our brains are doing (Kahneman, 2011). Exceptionally complex, cognition is an essential feature of human consciousness, yet not all aspects of cognition are consciously experienced. Accuracy and Inaccuracy in Memory and Cognition She Was Certain, but She Was Wrong: In 1984 Jennifer Thompson was a 22-year-old college student in North Carolina. Thompson went to the police that same day to create a sketch of her attacker, relying on what she believed was her detailed memory. Thompson identified Ronald Cotton as the rapist, and she later testified against him at trial. Consumed by guilt, Thompson sought out Cotton when he was released from prison, and they have since become friends (Innocence Project, n. They fail in part due to our inadequate encoding and storage, and in part due to our inability to accurately retrieve stored information. Memory is also influenced by the setting in which it occurs, by the events that occur to us after we have experienced an event, and by the cognitive processes that we use to help us remember. Although our cognition allows us to attend to , rehearse, and organize information, cognition may also lead to distortions and errors in our judgments and our behaviors. Cognitive biases are errors in memory or judgment that are caused by the inappropriate use of cognitive processes (see Table 5. Eichenbaum (1999) and Dunning, Griffin, Milojkovic, and Ross (1990) asked college students to predict how another student would react in various situations. The results were clear: Regardless of whether they judged a stranger or a roommate, the participants consistently overestimated the accuracy of their own predictions. Source monitoring the ability to accurately identify the Uncertainty about the source of a source of a memory memory may lead to mistaken judgments. Misinformation Errors in memory that occur when new, Eyewitnesses, based on the questions asked effect but incorrect information influences by the police, may change their memories existing accurate memories of what they observed at the crime scene. Confirmation bias the tendency to verify and confirm our Once beliefs become established, they existing memories rather than to become self-perpetuating and difficult to challenge and disconfirm them change. Functional fixedness When schemas prevent us from seeing Creativity may be impaired by the overuse and using information in new and of traditional, expectancy-based thinking. Representativeness Tendency to make judgments according to After a coin has come up head many times heuristic how well the event matches our in a row, we may erroneously think that the expectations next flip is more likely to be tails. Availability heuristic Idea that things that come to mind easily We may overestimate the crime statistics are seen as more common in our own area, because these crimes are so easy to recall. Eyewitnesses to crimes are also frequently overconfident in their memories, and there is only a small correlation between how accurate and how confident an eyewitness is. When we experience a situation with a great deal of emotion, we may form a flashbulb memory, which is a vivid and emotional memory of an unusual event that people believe they remember very well (Brown & Kulik, 1977). People are very certain of their memories of these important events, and are typically overconfident. Talarico and Rubin (2003) tested the accuracy of flashbulb memories by asking students to write down their memory of how they had heard the news about 160 either the September 11, 2001, terrorist attacks or about an everyday event that had occurred to them during the same time frame. The participants became less accurate in their recollections of both the emotional event and the everyday events over time, but the participants confidence in the accuracy of their memory of learning about the attacks did not decline over time. After 32 weeks the participants were overconfident; they were much more certain about the accuracy of their flashbulb memories than they should have been. Schmolck, Buffalo, and Squire (2000) found similar distortions in memories of news about the verdict in the O. Source monitoring refers to the ability to accurately identify the source of a memory. Perhaps you have had the experience of wondering whether you really experienced an event or only dreamed or imagined it. Rassin, Merkelbach, and Spaan (2001) reported that up to 25% of college students reported being confused about real versus dreamed events. Studies suggest that people who are fantasy-prone are more likely to experience source monitoring errors (Winograd, Peluso, & Glover, 1998), and such errors also occur more often for both children and the elderly, than for adolescents and younger adults (Jacoby & Rhodes, 2006). In other cases we may be sure that we remembered the information from real life, but be uncertain about exactly where we heard it. Imagine that you read a news story in a tabloid magazine such as the National Enquirer. Probably you would have discounted the information because you know that its source is unreliable. What if later you were to remember the story, but forget the source of the information If this happens, you might become convinced that the news story is true because you forgot to discount the source. The sleeper effect refers to attitude change that occurs over time when we forget the source of information (Pratkanis, Greenwald, Leippe, & Baumgardner, 1988). Misinformation Effects A particular problem for eyewitnesses, such as Jennifer Thompson, is that our memories are often influenced by the things that occur to us after we have learned the information (Erdmann, Volbert, & Bohm, 2004; Loftus, 1979; Zaragoza, Belli, & Payment, 2007). This new information can distort our original memories such that we are no longer sure what is the real information and what was provided later. The misinformation effect refers to errors in memory that occur when new information influences existing memories. In an experiment by Loftus and Palmer (1974), participants viewed a film of a traffic accident and then, according to random assignment to experimental conditions, answered one of three questions: 161 Figure 5. According to random assignment, the verb in the question was filled by either hit, smashed, or contacted each other. Reconstruction of automobile destruction: An example of the interaction between language and memory. Participants who had been asked about the cars smashing each other estimated the highest average speed, and those who had been asked the contacted question estimated the lowest average speed. Loftus and her colleagues asked parents to provide them with descriptions of events that did, such as moving to a new house, and did not, suc as being lost in a shopping mall, happen to their children. Then without telling the children which events were real or made-up, the researchers asked the children to imagine both types of events. The children were instructed to think real hard about whether the events had occurred (Ceci, Huffman, Smith, & Loftus, 1994). More than half of the children generated stories regarding at least one of the made-up events, and they remained insistent that the events did in fact occur, even when told by the researcher that they could not possibly have occurred (Loftus & Pickrell, 1995). Even college students are susceptible to manipulations that make events that did not actually occur seem as if they did (Mazzoni, Loftus, & Kirsch, 2001). The ease with which memories can be created or implanted is particularly problematic when the events to be recalled have important consequences. Some therapists argue that patients may repress memories of traumatic events they experienced as children, such as childhood sexual abuse, and then recover the events years later as the therapist leads them to recall the information by using techniques, such as dream interpretation and hypnosis (Brown, Scheflin, & Hammond, 1998). Other researchers argue that painful memories, such as sexual abuse, are usually very well remembered, that few memories are actually repressed, and that even if they are it is virtually impossible for patients to accurately retrieve them years later (McNally, Bryant, & Ehlers, 2003; Pope, Poliakoff, Parker, Boynes, & Hudson, 2007). Because hundreds of people have been accused, and even imprisoned, on the basis of claims about recovered memory of child sexual abuse, the accuracy of these memories has important societal 162 implications. Many psychologists now believe that most of these claims of recovered memories are due to implanted, rather than real, memories (Loftus & Ketcham, 1994). Distortions Based on Expectations We have seen that schemas help us remember information by organizing material into coherent representations. However, although schemas can improve our memories, they may also lead to cognitive biases. The confirmation bias leads us to remember information that fits our schemas better than we remember information that disconfirms them (Stangor & McMillan, 1992), a process that makes our stereotypes very difficult to change. In short, once we begin to believe in something, such as a stereotype about a group of people, it becomes very difficult to later convince us that these beliefs are not true; the beliefs become self-confirming. Darley and Gross (1983) demonstrated how schemas about social class could influence memory. In their research they gave participants a picture and some information about a fourth-grade girl named Hannah. To activate a schema about her social class, Hannah was pictured sitting in front of a nice suburban house for one-half of the participants and pictured in front of an impoverished house in an urban area for the other half. Then the participants watched a video that showed Hannah taking an intelligence test. Then the participants were asked to remember how many questions Hannah got right and wrong. Demonstrating that stereotypes had influenced memory, the participants who thought that Hannah had come from an upper-class background remembered that she had gotten more correct answers than those who thought she was from a lower-class background. Schemas can not only distort our memory, but our reliance on schemas can also make it more difficult for us to think outside the box. The first guess that students made was usually consecutive ascending even numbers, and they then asked questions designed to confirm their hypothesis: (Does 102-104-106 fit They never bothered to ask whether 1-2-3 or 3-11-200 would fit, and if they had they would have learned that the rule was not consecutive ascending even numbers, but simply any three ascending numbers. Duncker (1945) gave participants a candle, a box of thumbtacks, and a book of matches, and asked them to attach the candle to the wall so that it did not drip onto the table below (see Figure 5. Few of the participants realized that the box could be tacked to the wall and used as a platform to hold the candle. The problem again is that our existing memories are powerful, and they bias the way we think about new information. In the candle-tack-box problem, functional Salience and Cognitive Accessibility fixedness may lead us to see the box only as a box and not as a potential candleholder Still another potential for bias in memory occurs because we are more likely to attend to , and thus make use of and remember, some information more than other information. Things that are unique, colorful, bright, moving, and unexpected are more salient (McArthur & Post, 1977; Taylor & Fiske, 1978). In one relevant study, Loftus, Loftus, and Messo (1987) showed people images of a customer walking up to a bank teller and pulling out either a pistol or a checkbook. The salience of the stimuli in our social worlds has a big influence on our judgment, and in some cases, may lead us to behave in ways that we might better not have. You checked Consumer Reports online and found that, after reviewing price, gas mileage, safety, and options, you decided to purchase a particular vehicle. You tell her that you were thinking of buying a different model, and she tells you that you are crazy. She says she knows someone who had that car and it had a lot of problems, and she would never buy one.

In this section we will review the history of psychology with a focus on the important questions that psychologists ask and the major approaches (or schools) of psychological inquiry 85 medications that interact with grapefruit discount 100 ml mentat ds syrup with visa. Perhaps most importantly, the field has moved steadily from speculation about behavior toward a more objective and scientific approach as the [1] technology available to study human behavior has improved (Benjamin & Baker, 2004). Although most early psychologists were men, now most psychologists, including the presidents of the most important psychological organizations, are women. Structuralism structures of psychological experience Titchener Attempts to understand why animals and humans have developed the Functionalism particular psychological aspects that they currently possess William James Focuses on the role of our unconscious thoughts, feelings, and Sigmund Freud, Carl Jung, Psychodynamic memories and our early childhood experiences in determining behavior Alfred Adler, Erik Erickson Based on the premise that it is not possible to objectively study the mind, and therefore that psychologists should limit their attention to John B. Are genes or environment most influential in determining the behavior of individuals and in accounting for differences among people Most scientists now agree that both genes and environment play crucial roles in most human behaviors, and yet we still have much to learn about how nature (our biological makeup) and nurture (the experiences that we have during our lives) work together (Harris, 1998; Pinker, [2] 2002). We will see, for example, that the heritability of intelligence is very high (about. But we will also see that nature and nurture interact in complex ways, making the question of Is it nature or is it nurture This question concerns the extent to which people have control over their own actions. Are we the products of our environment, guided by forces out of our control, or are we able to choose the behaviors we engage in And our legal system is premised on the concept of free will; we punish criminals because we believe that they have choice over their behaviors and freely choose to disobey the law. But as we will discuss later in the research focus in this section, recent research has suggested that we may have less control over our own [3] behavior than we think we do (Wegner, 2002). Although it appears that people are good enough to make sense of the world around [4] them and to make decent decisions (Fiske, 2003), they are far from perfect. Human judgment is sometimes compromised by inaccuracies in our thinking styles and by our motivations and emotions. To what extent are we conscious of our own actions and the causes of them, and to what extent are our behaviors caused by influences that we are not aware offi Many of the major theories of psychology, ranging from the Freudian psychodynamic theories to contemporary work in cognitive psychology, argue that much of our behavior is determined by variables that we are not aware of. For instance, are there basic psychological and personality differences between men and women, or are men and women by and large similar Are people around the world generally the same, or are they influenced by their backgrounds and environments in different ways In terms of the former, Plato argued on the nature side, believing that certain kinds of knowledge are innate or inborn, whereas Aristotle was more on the nurture side, believing that each child is born as an empty slate (in Latin atabula rasa) and that knowledge is primarily acquired through learning and experience. European philosophers continued to ask these fundamental questions during the Renaissance. A scientist as well as a philosopher, Descartes dissected animals and was among the first to understand that the nerves controlled the muscles. Descartes believed in the principle ofdualism: that the mind is fundamentally different from the mechanical body. The fundamental problem that these philosophers faced was that they had few methods for settling their claims. Most philosophers didnt conduct any research on these questions, in part because they didnt yet know how to do it, and in part because they werent sure it was even possible to objectively study human experience. Wundt began the field known as structuralism, a school of psychology whose goal was to identify the basic elements or structures of psychological experience. Its goal was to create a periodic table of the elements of sensations, similar to the periodic table of elements that had recently been created in chemistry. Structuralists used the method of introspection to attempt to create a map of the elements of consciousness. Introspection involves asking research participants to describe exactly what they experience as they work on mental tasks, such as viewing colors, reading a page in a book, or performing a math problem. In other studies the structuralists used newly invented reaction time instruments to systematically assess not only what the participants were thinking but how long it took them to do so. These studies marked the first time researchers realized that there is a difference between the sensation of a stimulus and theperception of that stimulus, and the idea of using reaction times to study mental events has now become a mainstay of cognitive psychology. Titchener was a student of Wundt who came to the United States in the late 1800s and founded a laboratory at Cornell University. An important aspect of the structuralist approach was that it was rigorous and scientific. The research marked the beginning of psychology as a science, because it demonstrated that mental events could be quantified. Even highly trained research participants were often unable to report on their subjective experiences. Functionalism and Evolutionary Psychology In contrast to Wundt, who attempted to understand the nature of consciousness, the goal of William James and the other members of the school of functionalism was to understand why animals and humans have developed the particular psychological aspects that they currently [5] possess(Hunt, 1993). As he put it in his psychology textbook, My thinking is first and last and always for the sake of my doing [6] (James, 1890). Just as some animals have developed strong muscles to allow them to run fast, the human brain, so functionalists thought, must have adapted to serve a particular function in human experience. Although functionalism no longer exists as a school of psychology, its basic principles have been absorbed into psychology and continue to influence it in many ways. The work of the functionalists has developed into the field ofevolutionary psychology, a branch of psychology that applies the Darwinian theory of natural selection to human and animal behavior(Dennett, [7] 1995; Tooby & Cosmides, 1992). As we will see in the chapters to come, evolutionary psychologists use evolutionary theory to understand many different behaviors including romantic attraction, stereotypes and prejudice, and even the causes of many psychological disorders. Fitness refers to the extent to which having a given characteristic helps the individual organism survive and reproduce at a higher rate than do other members of the species who do not have the characteristic. For example, it has been argued that the emotion of jealousy has survived over time in men because men who experience jealousy are more fit than men who do not. According to this idea, the experience of jealously leads men to be more likely to protect their [8] mates and guard against rivals, which increases their reproductive success (Buss, 2000). Unlike the fossils that are used to learn about the physical evolution of species, we cannot know which psychological characteristics our ancestors possessed or did not possess; we can only make guesses about this. Because it is difficult to directly test evolutionary theories, it is always possible that the explanations we apply are made up after the fact to account for observed data [9] (Gould & Lewontin, 1979). Psychodynamic psychology is an approach to understanding human behavior that focuses on the role of unconscious thoughts, feelings, and memories. Freud developed his theories about behavior through extensive analysis of the patients that he treated in his private clinical practice. Freud believed that many of the problems that his patients experienced, including anxiety, depression, and sexual dysfunction, were the result of the effects of painful childhood experiences that the person could no longer remember. These explorations are revealed through talk therapy and dream analysis, in a process called psychoanalysis. The founders of the school of psychodynamics were primarily practitioners who worked with individuals to help them understand and confront their psychological symptoms. Although they did not conduct much research on their ideas, and although later, more sophisticated tests of their theories have not always supported their proposals, psychodynamics has nevertheless had substantial impact on the field of psychology, and indeed on thinking about human behavior [10] more generally (Moore & Fine, 1995). The importance of the unconscious in human behavior, the idea that early childhood experiences are critical, and the concept of therapy as a way of improving human lives are all ideas that are derived from the psychodynamic approach and that remain central to psychology. The psychologists associated with the school of behaviorism, on the other hand, were reacting in part to the difficulties psychologists encountered when they tried to use introspection to understand behavior. Behaviorism is a school of psychology that is based on the premise that it is not possible to objectively study the mind, and therefore that psychologists should limit their attention to the study of behavior itself. They argue that there is no point in trying to determine what happens in the box because we can successfully predict behavior without knowing what happens inside the mind. Furthermore, behaviorists believe that it is possible to develop laws of learning that can explain all behaviors. Watson and the other behaviorists began to use these ideas to explain how events that people and other organisms experienced in their environment (stimuli) could produce specific behaviors (responses). In his research Watson found that systematically exposing a child to fearful stimuli in the presence of objects that did not themselves elicit fear could lead the child to respond with a fearful behavior to the presence of the stimulus (Watson & Rayner, 1920; Beck, Levinson, & [11] Irons, 2009). In the best known of his studies, an 8-month-old boy named Little Albert was used as the subject. Here is a summary of the findings: the boy was placed in the middle of a room; a white laboratory rat was placed near him and he was allowed to play with it. In line with the behaviorist approach, the boy had learned to associate the white rat with the loud noise, resulting in crying. Skinner used the ideas of stimulus and response, along with the application of rewards or reinforcements, to train pigeons and other animals. And he used the general principles of behaviorism to develop theories about how best to teach children and how to create societies that were peaceful and productive. Skinner even developed a method for studying thoughts and [12] feelings using the behaviorist approach (Skinner, 1957, 1968, 1972). The behaviorist research program had important implications for the fundamental questions about nature and nurture and about free will. In terms of the nature-nurture debate, the behaviorists agreed with the nurture approach, believing that we are shaped exclusively by our environments. They also argued that there is no free will, but rather that our behaviors are determined by the events that we have experienced in our past. In short, this approach argues that organisms, including humans, are a lot like puppets in a show who dont realize that other people are controlling them. Furthermore, although we do not cause our own actions, we nevertheless believe that we do because we dont realize all the influences acting on our behavior. Recent research in psychology has suggested that Skinner and the behaviorists might well have been right, at least in the sense that we overestimate our own free will in responding to the events around us (Libet, 1985; Matsuhashi & [13] Hallett, 2008; Wegner, 2002). The participants were asked, whenever they decided to , to press either of two buttons. Then they were asked to indicate which letter was showing on the screen when they decided to press the button. The researchers analyzed the brain images to see if they could predict which of the two buttons the participant was going to press, even before the letter at which he or she had indicated the decision to press a button. Research has found that we are more likely to think that we control our behavior when the desire to act occurs immediately prior to the outcome, when the thought is consistent with the outcome, and when there are no other [15] apparent causes for the behavior. Aarts, Custers, and Wegner (2005) asked their research participants to control a rapidly moving square along with a computer that was also controlling the square independently. When participants were exposed to words related to the location of the square just before they stopped its movement, they became more likely to think that they controlled the motion, even when it [16] was actually the computer that stopped it. And Dijksterhuis, Preston, Wegner, and Aarts (2008) found that participants who had just been exposed to first-person singular pronouns, such as I and me, were more likely to believe that they controlled their actions than were people who had seen the words computer or God. Because we normally expect that our behaviors will be met with success, when we are successful we easily believe that the success is the result of our own free will. When an action is met with failure, on the other hand, we are less likely to perceive this outcome as the result of our free will, and we are more likely to [17] blame the outcome on luck or our teacher (Wegner, 2003). The behaviorists made substantial contributions to psychology by identifying the principles of learning. Although the behaviorists were incorrect in their beliefs that it was not possible to measure thoughts and feelings, their ideas provided new ideas that helped further our understanding regarding the nature-nurture debate as well as the question of free will. The ideas of behaviorism are fundamental to psychology and have been developed to help us better understand the role of prior experiences in a variety of areas of psychology. The Cognitive Approach and Cognitive Neuroscience Science is always influenced by the technology that surrounds it, and psychology is no exception.
