Previous eyewitness memory research has shown that biased lineup instructions reduce identification accuracy, primarily by increasing false-positive identifications in target-absent lineups. Because some attempts at identification do not rely on a witness's memory of the perpetrator but instead involve matching photos to images on surveillance video, the authors investigated the effects of biased instructions on identification accuracy in a matching task. In Experiment 1, biased instructions did not affect the overall accuracy of participants who used video images as an identification aid, but nearly all correct decisions occurred with target-present photo spreads. Both biased and unbiased instructions resulted in high false-positive rates. In Experiment 2, which focused on video-photo matching accuracy with target-absent photo spreads, unbiased instructions led to more correct responses (i.e., fewer false positives). These findings suggest that investigators should not relax precautions against biased instructions when people attempt to match photos to an unfamiliar person recorded on video. 相似文献

This article describes a study that examined the relationship between multiple Axis I mental health diagnoses and treatment outcomes for female offenders in prison substance abuse treatment programs. Preliminary findings of the effectiveness of therapeutic community (TC) treatment, modified for female offenders, relative to a control cognitive behavioral treatment condition, are presented. The hypothesis--that participants who fit into multiple diagnostic categories have more dysfunctional symptoms and behaviors at baseline--was confirmed; however, a hypothesized relationship between the number of Axis I diagnoses and 6 month treatment outcomes across five domains (mental health, trauma exposure, substance use, HIV needle risk behaviors, and HIV sexual risk) was not supported. Across all Axis I mental health groups, TC treatment was significantly more effective than the control condition overall, as well as on measures of mental health symptoms and HIV sexual risk. These findings suggest that this TC treatment program, as modified, is an effective model for women with varied diagnoses and diagnostic complexities. 相似文献

People are typically overly optimistic when evaluating the quality of their performance on social and intellectual tasks. In particular, poor performers grossly overestimate their performances because their incompetence deprives them of the skills needed to recognize their deficits. Five studies demonstrated that poor performers lack insight into their shortcomings even in real world settings and when given incentives to be accurate. An additional meta-analysis showed that it was lack of insight into their own errors (and not mistaken assessments of their peers) that led to overly optimistic estimates among poor performers. Along the way, these studies ruled out recent alternative accounts that have been proposed to explain why poor performers hold such positive impressions of their performance. 相似文献

Renewal of an extinguished conditioned response has been demonstrated in humans and in animals using various types of procedures, except renewal of motor learning such as eyeblink conditioning. We tested renewal of delay and trace eyeblink conditioning in a virtual environment in an ABA design. Following acquisition in one context (A, e.g., an airport) and extinction in a different context (B, e.g., a city), tests for renewal took place in the acquisition (A) and extinction context (B), in a counterbalanced order. Results showed renewal of the extinguished conditioned response in the delay but not trace condition. 相似文献

Superstitions and anti-Semitism are generally based on irrational beliefs. To date, no research has examined the relationship between anti-Semitism and superstition. Four groups, Arab-Muslim, Arab-Christian, Non-Arab Muslim, and Non-Arab Christian, responded to anti-Semitism and superstition measures. With respect to anti-Semitism scores, Arabs scored higher than non-Arabs and Muslims scored higher than Christians. Superstitions varied, however, with Arabs endorsing more New Age beliefs, while Muslims endorsed more traditional superstitious beliefs. The correlations between anti-Semitism and superstitious beliefs were significant, but low, and are explained in terms of cultural differences. 相似文献

Following Marc Richir and others, László Tengelyi has recently developed the idea of Sinnereignis (meaning-event) as a way of capturing the emergence of meaning that does not flow from some prior project or constitutive act. As such, it might seem to pose something of a challenge to phenomenology: the paradox of an experience that is mine without being my accomplishment. This article offers a different sort of interpretation of meaning-events, claiming that in their structure they always involve what the late Heidegger called “measure-taking” (Maß-nehmen)—that is, an orientation toward the emergence of normative moments thanks to which what apparently eludes phenomenology becomes accessible in its inaccessibility. This is shown, first, on the example of conscience in Sein und Zeit and then on the example of the poetic image (Bild) in Heidegger’s later essays. 相似文献

The constant-RPE tracking model monitors progress over the course of exercise training. During aerobic exercise, prior work using this model has demonstrated similar relative intensities pre- and posttraining, while the absolute workload increases posttraining. However, the prediction equation associated with these changes has not been examined during resistance training. 22 men and 27 women (M age 64 yr.) participated in a 12-wk. resistance training. Orientation determined resistances associated with RPEs of 4, 5-6, 7-8, and 9 on the OMNI-Resistance Exercise Scale for each of seven exercises for each participant. Individuals trained 3 days a week for 12 wk. Linear regression was used to calculate percent of 1-repetition maximum (%1-RM) at RPE 4, 6, and 8 for the exercises. Paired sample t tests, comparing pre- and posttraining %1-RMs at each RPE, indicated that posttraining %1-RMs were higher for RPE 4 and 6 for each exercise, while at RPE 8, results were significant for only 3 exercises. Thus for at least the RPE 4 and 6, the constant RPE tracking model is appropriate for resistance exercise; however, the equation of prediction appears to differ from that for aerobic exercise. Development of a new prediction equation may be necessary to track relative strength in older adults. 相似文献

Dissociation is typically defined as the lack of normal integration of thoughts, feelings, and experiences into consciousness and memory. The present article critically evaluates the research literature on cognitive processes in dissociation. The authors' review indicates that dissociation is characterized by subtle deficits in neuropsychological performance (e.g., heightened distractibility). Some of the cognitive phenomena (e.g., weakened cognitive inhibition) associated with dissociation appear to be dependent on the emotional or attentional context. Contrary to a widespread assumption in the clinical literature, dissociation does not appear to be related to avoidant information processing. Rather, it is associated with an enhanced propensity toward pseudo-memories, possibly mediated by heightened levels of interrogative suggestibility, fantasy proneness, and cognitive failures. Evidence for a link between dissociation and either memory fragmentation or early trauma based on objective measures is conspicuously lacking. The authors identify a variety of methodological issues and discrepancies that make it difficult to articulate a comprehensive framework for cognitive mechanisms in dissociation. The authors conclude with a discussion of research domains (e.g., sleep-related experiences, drug-related dissociation) that promise to advance our understanding of cognition and dissociation. 相似文献

Promoting early adolescents' achievement and peer relationships: the effects of cooperative, competitive, and individualistic goal structures 总被引:1,自引:0,他引:1
Emphasizing the developmental need for positive peer relationships, in this study the authors tested a social-contextual view of the mechanisms and processes by which early adolescents' achievement and peer relationships may be promoted simultaneously. Meta-analysis was used to review 148 independent studies comparing the relative effectiveness of cooperative, competitive, and individualistic goal structures in promoting early adolescents' achievement and positive peer relationships. These studies represented over 8 decades of research on over 17,000 early adolescents from 11 countries and 4 multinational samples. As predicted by social interdependence theory, results indicate that higher achievement and more positive peer relationships were associated with cooperative rather than competitive or individualistic goal structures. Also as predicted, results show that cooperative goal structures were associated with a positive relation between achievement and positive peer relationships. Implications for theory and application are discussed. 相似文献
