Confidence,not consistency,characterizes flashbulb memories 总被引:5,自引:0,他引:5
On September 12, 2001, 54 Duke students recorded their memory of first hearing about the terrorist attacks of September 11 and of a recent everyday event. They were tested again either 1, 6, or 32 weeks later. Consistency for the flashbulb and everyday memories did not differ, in both cases declining over time. However, ratings of vividness, recollection, and belief in the accuracy of memory declined only for everyday memories. Initial visceral emotion ratings correlated with later belief in accuracy, but not consistency, for flashbulb memories. Initial visceral emotion ratings predicted later posttraumatic stress disorder symptoms. Flashbulb memories are not special in their accuracy, as previously claimed, but only in their perceived accuracy. 相似文献

The authors examined how a crime schema influenced the types of details witnesses recalled over multiple interviews that varied in delay before the initial interview and between subsequent interviews. Accuracy data showed that, in general, schema-irrelevant traces experienced greater decay than schema-consistent and schema-inconsistent traces after the initial interview and that delaying the initial interview negatively affected recall at the initial interview but led to less decay over subsequent interviews. Ambiguity of the crime stimulus was also manipulated. Witnesses used their schema to interpret ambiguous information and, as a result, made more schema-consistent intrusions and less correct responses and were more likely to report false memories that involved conscious recollection (using the remember-know paradigm). 相似文献

Heterogeneity in the performance of persons affected with schizophrenia or schizotypic psychopathology on various laboratory tasks has long been recognized, both for its consistency across tasks and studies and for the massive methodological and substantive challenges it poses for experimental psychopathology, genetic, and other investigations. Traditional multivariate techniques, such as factor analysis, discriminant function analysis, and cluster analysis, have all been deemed inadequate for resolving heterogeneity, because of one or another statistical limitation. Here, an objective statistical approach based on a formal statistical model that uses the ubiquitous and well-developed expectation-maximization (EM) algorithm (A. P. Dempster, N. M. Laird, & D. B. Rubin, 1977) is presented, which enables one effectively to partition a group of experimental subjects, in this case identified initially using the well-known Perceptual Aberration Scale (L. J. Chapman, J. P. Chapman, & M. L. Raulin, 1978), in a manner that reduces heterogeneity and allows for the separation of what are termed genuine and false-positive schizotypes. The validity of the parsing strategy was supported by reference to other laboratory indexes of relevance to schizophrenia and schizotypy that were not included in the initial EM-based analyses. The potential utility of this approach is discussed with reference to future schizophrenia and schizotypy research. 相似文献

Using Tulving's (1985) remember/know procedure, the present research investigated the experiential concomitants of person recognition. Noting basic differences in the manner in which the mind processes expectancy-related material, it was anticipated that facial typicality would be a critical determinant of people's recollective experiences (i.e., remembering vs knowing). In particular, it was expected that whereas remember responses would be more prevalent for distinctive than typical faces, know responses would reflect the opposite pattern. The results of two experiments provided general support for these predictions. In addition, the recollective advantage for distinctive faces was traced to the availability of attentional resources at encoding. These results are considered in the context of contemporary issues in person recognition and social cognition. 相似文献

As a means of examining the incremental validity of a normal personality measure in the prediction of selected Axis I and II diagnoses, 1,342 inpatient substance abusers completed the Revised NEO Personality Inventory (NEO-PI-R) and the Minnesota Multiphasic Personality Inventory--2 (MMPI-2) and were assessed with structured clinical interviews to determine diagnostic status. Results demonstrated that scores from the NEO-PI-R (a) were substantially related to the majority of diagnoses, accounting for between 8% and 26% of the variance in the diagnostic criteria; (b) explained an additional 3% to 8% of the variability beyond 28 selected MMPI-2 scale scores; (c) increased diagnostic classification an additional 7% to 23% beyond MMPI-2 scale scores; and (d) were significantly more useful when examined at the facet trait level than at the domain trait level. Implications for incorporating measures of normal personality into clinical assessment batteries are discussed. 相似文献

Stress exerts deleterious effects on the cardiovascular system. Left ventricular hypertrophy has been identified as a risk factor for heart disease. The effects of stress on other heart parameters, including heart size and heart shape, are not well-characterized. In addition, the extent to which males and females differ in stress effects on these measures has not been examined, but may help to further explain gender differences in heart disease morbidity and mortality. The present experiment examined effects of mild daily stress on heart morphology and blood volume (obtained by ex-sanguination at decapitation) in 39 male and 40 female rats of two strains. Following 14 days of stress exposure, rats were killed and blood volume was measured. Heart length, heart weight, left ventricle cavity width, right ventricle width, lateral wall thickness, anterior wall thickness, posterior wall thickness, and septal wall thickness were measured. In males, after controlling for body weight, stress decreased heart length and left ventricle cavity width and increased septal wall thickness. In females, after controlling for body weight, stress reduced total blood volume, but did not significantly affect other heart parameters. These findings suggest that stress exposure can alter heart morphology and blood volume and that there are sex differences in these effects. 相似文献

《Behaviour research and therapy》1969,7(4):381-386The 122 item fear survey schedule was factor analyzed in an attempt to discover whether various stimuli cluster together in their capacity to evoke anxiety. The method of factor analysis involved a rotation to an oblique structure with the result that 5 conceptually pure factors emerged accounting for at least 90 per cent of the variance. The factors were named as follows: (1) fears related to small animals, (2) fears of the precipitators and manifestations of hostility, (3) moralistically related fears and sexual fears, (4) fears of isolation and loneliness, and (5) fears of anatomical destruction and physical pain. Using the items that correlated 0.35 or better with factors, a 40 item fear survey schedule emerged. Suggestions for clinical use of this fear survey schedule were made. 相似文献

The distribution of early childhood memories 总被引:2,自引:0,他引:2
Rubin DC 《Memory (Hove, England)》2000,8(4):265-269
The quantitative distribution of autobiographical memories for the first decade of life is described. The distribution, based on over 11,000 autobiographical memories from age 10 and younger from published studies, is nearly identical for males and females, for participants of different ages, and for different methods of collecting data, including using words to cue memories from anywhere in the lifespan or from just the childhood years, exhaustive listing of all early memories, and interviews. 相似文献
