Recent work by Hupbach, Gomez, Hardt, and Nadel (Learning & Memory, 14, 47–53, 2007) and Hupbach, Gomez, and Nadel (Memory, 17, 502–510, 2009) suggests that episodic memory for a previously studied list can be updated to include new items, if participants are reminded
of the earlier list just prior to learning a new list. The key finding from the Hupbach studies was an asymmetric pattern
of intrusions, whereby participants intruded numerous items from the second list when trying to recall the first list, but
not viceversa. Hupbach et al. (2007; 2009) explained this pattern in terms of a cellular reconsolidation process, whereby first-list memory is rendered labile by the
reminder and the labile memory is then updated to include items from the second list. Here, we show that the temporal context
model of memory, which lacks a cellular reconsolidation process, can account for the asymmetric intrusion effect, using well-established
principles of contextual reinstatement and item–context binding. 相似文献

There is considerable evidence that children and adolescents with autistic spectrum disorders (ASD) are at increased risk
of anxiety and anxiety disorders. However, it is less clear which of the specific DSM-IV anxiety disorders occur most in this
population. The present study used meta-analytic techniques to help clarify this issue. A systematic review of the literature
identified 31 studies involving 2,121 young people (aged <18 years) with ASD, and where the presence of anxiety disorder was
assessed using standardized questionnaires or diagnostic interviews. Across studies, 39.6% of young people with ASD had at
least one comorbid DSM-IV anxiety disorder, the most frequent being specific phobia (29.8%) followed by OCD (17.4%) and social
anxiety disorder (16.6%). Associations were found between the specific anxiety disorders and ASD subtype, age, IQ, and assessment
method (questionnaire versus interview). Implications for the identification and treatment of anxiety in young people with
ASD are discussed. 相似文献

The category adjustment model (CAM) proposes that estimates of inexactly remembered stimuli are adjusted toward the central value of the category of which the stimuli are members. Adjusting estimates toward the average value of all category instances, properly weighted for memory uncertainty, maximizes the average accuracy of estimates. Thus far, the CAM has been tested only with symmetrical category distributions in which the central stimulus value is also the mean. We report two experiments using asymmetric (skewed) distributions in which there is more than one possible central value: one where the frequency distribution shifts over the course of time, and the other where the frequency distribution is skewed. In both cases, we find that people adjust estimates toward the category’s running mean, which is consistent with the CAM but not with alternative explanations for the adjustment of stimuli toward a category’s central value. 相似文献

Five experiments provide evidence for a primacy effect in the formation of inductive categories. Participants completed a category induction task in which they observed and reproduced a set of lines that varied in length but were serially ordered so that they increased or decreased in length. Subsequent estimates of the average of the distribution were systematically biased in the direction of stimuli encountered at the beginning of the induction task, suggesting that initially encountered stimuli exert greater weight in a category representation than do subsequent stimuli. We offer possible explanations for why this primacy effect might arise. 相似文献

Research in the area of self-handicapping has consistently demonstrated a robust yet puzzling gender difference in the use of and evaluation of behavioral self-handicaps; women (1) are less likely to use these forms of handicaps, particularly those involving the actual or reported reduction of effort, and (2) evaluate the use of these handicaps by others more negatively than do men. The present research examines several possible explanations for these consistent gender differences and finds that the personal value placed on effort is an important mediator of these effects. 相似文献

Using the Zimbardo Time Perspective Inventory (ZTPI; P. G. Zimbardo & J. N. Boyd, 1999), the authors found that homeless people, in comparison with a control group, had a significantly more negative outlook concerning their past and present as evinced by high Past-Negative and Present-Fatalistic scores and low Past-Positive scores on the ZTPI. However, the homeless individuals were almost indistinguishable from control participants on measures of Present-Hedonism and Future thinking. The homeless individuals had significantly higher levels of depression, with 31 out of 50 (62%) reaching criteria for probable depression. However, this finding was unrelated to their atypical time perspective. There was no significant relation between substance misuse and time perspective. Despite their current difficulties, including depression and drug abuse, the homeless individuals maintained a propensity toward future thinking characterized by striving to achieve their goals. 相似文献

In the following study, participants encoded blocked DRM word lists and we varied whether they received information before test about the utility of mnemonic features that potentially discriminate between veridical and false memories. The results of three experiments revealed that this manipulation successfully reduced false recognition of critical theme words. We also found that this manipulation was effective for younger but not older adults. Furthermore, calling attention to the features in test instructions alone was sufficient for reducing false recognition and its effectiveness was not enhanced by also asking participants to rate their phenomenal experience. We argue that providing diagnostic information before test allows participants to establish more accurate expectations about the task and thus improves the efficacy of retrieval and monitoring processes that are subsequently engaged. 相似文献

ObjectiveThe objective was to develop and validate an achievement goal scale for young athletes that was aligned with the 2 (mastery/ego)×2 (approach/avoidance) achievement goal framework.MethodA total of 1675 male and female athletes ranging in age from 9 to 14 years participated in the AGSYS scale development and validation phases. Items having a readability level of grade 4 (age 9) or below were written and evaluated in a series of studies to assess the reliability, factorial validity, and construct validity of the Mastery and Ego scales.DesignBoth correlational and experimental methods were used to assess reliability and validity.ResultsExploratory and confirmatory factor analyses demonstrated factorial validity in samples of 9–10-, 11–12-, and 13–14-year-old athletes, and the subscales correlated in a predicted fashion with one another, with other sport and academic goal orientation measures and with several other theoretically relevant variables, including coach-initiated motivational climate, competitive trait anxiety, sport enjoyment, motivation, and self-esteem. Scores also changed significantly in response to a motivational climate coach intervention.ConclusionThe Achievement Goal Scale for Youth Sports (AGSYS) appears to be a reliable and valid measure of achievement goal approach orientations in children between the ages of 9 and 14 years. We were not successful in developing corresponding avoidance goal orientation scales that were not highly correlated, raising the possibility that children do not cognitively differentiate between mastery-avoidance and ego-avoidance orientations. 相似文献
