Two experiments addressed the question of whether news reports depicting base‐rate data indicative of increasing population size over time would assuage the apprehension and victimization risk associated with another news story depicting frequency increases in a threatening phenomenon during the same time period. Men exposed to the population data manifested lower levels of apprehension and victimization risk than men not exposed to such data, but women showed no reduction in either apprehension and victimization risk than men not exposed to such data, but women showed no reduction in either apprehension or victimization risk after exposure to population data. This interaction was replicated in both experiments. Experiment 2 demonstrated that the same interaction can be produced using base‐rate data other than that depicting population increases over time and that the effects of the base‐rate stories are not merely a product of distraction from the threatening story. Differences in apprehension levels, information processing styles, mathematical problems solving skill, and sex role response sets were considered as alternative explanations for the interaction. 相似文献

While some studies suggest cultural differences in visual processing, others do not, possibly because the complexity of their tasks draws upon high‐level factors that could obscure such effects. To control for this, we examined cultural differences in visual search for geometric figures, a relatively simple task for which the underlying mechanisms are reasonably well known. We replicated earlier results showing that North Americans had a reliable search asymmetry for line length: Search for long among short lines was faster than vice versa. In contrast, Japanese participants showed no asymmetry. This difference did not appear to be affected by stimulus density. Other kinds of stimuli resulted in other patterns of asymmetry differences, suggesting that these are not due to factors such as analytic/holistic processing but are based instead on the target‐detection process. In particular, our results indicate that at least some cultural differences reflect different ways of processing early‐level features, possibly in response to environmental factors. 相似文献

What is the effect of retention interval on accurate and false recollection in the Deese, Roediger, and McDermott (DRM) procedure? Previous research has suggested that false recall is more persistent than accurate recall, but the recognition results have been inconsistent. In two parametric studies, we tested recall and recognition for the same DRM lists, over retention intervals that ranged from no delay to a 2-month delay. We found that accurate and false memory were diminished by increases in retention interval, false memory persistence was present for recall and recognition, greater persistence for false memory than for accurate memory was more readily observed for recall than recognition, and the highthreshold (Pr), signal detection (d’), and nonparametric (A’) recognition measures differed in their sensitivity for detecting change. The effect of retention interval on accurate and false memory is consistent with expectations from fuzzy trace theory. In the DRM procedure, truth is not more memorable than fiction. 相似文献

Attending psychiatrists completed an anchored version of the 18-item Brief Psychiatric Rating Scale (BPRS-A) based on admission and evaluation information on a total of 2,921 adult patients treated at 1 public sector acute psychiatric teaching hospital. Exploratory factor analysis was applied to a 6-month sample to construct 4 nonoverlapping subscales: Resistance, Positive Symptoms, Negative Symptoms, and Psychological Discomfort. Confirmatory factor analysis compared these new subscales to 3 other published subscale models using a second 6-month sample. Internal consistency, rater influence, and interrater agreement were estimated in separate studies. Discriminant validity was explored by comparison of diagnosis-based samples. Application of the BPRS-A as a debriefing instrument in the study of symptomatic change and the multiple challenges inherent in psychometric study of such a rating scale in realistic hospital practice are discussed. 相似文献

We administered the Tower of Hanoi to demographically comparable samples of control participants (n = 34) and children with the Combined (n = 22) and Inattentive subtypes (n = 19) of Attention-Deficit/Hyperactivity Disorder (ADHD). Controls excelled over children with the Inattentive subtype, who
outperformed patients with the Combined subtype. These results replicated findings of greater executive deficits in the Combined
than in the Inattentive type of ADHD. Double-blind administration of methylphenidate improved task performance only for patients
with the Inattentive subtype. In a drug-free Baseline session, children with both subtypes of ADHD made more private verbalizations
than controls, particularly when failing puzzles. In later sessions, regardless of drug condition, the inattentive sample
exhibited a smaller increase in self-regulatory utterances under failure. In contrast, the combined sample decreased self-regulatory
verbalizations under failure only under methylphenidate. The results support some differences between the two subtypes of
ADHD in executive functioning and in their response to stimulant therapy.
Portions of these results were submitted as part of H. Theresa Chang's PhD dissertation (Chang, 2000) and Helena Kopecky's
unpublished master's research, both conducted at the University of Rochester and supervised by Rafael Klorman. 相似文献
