The way in which people estimate when an event occurred and the accuracy of their estimates are of concern both to psychologists interested in the structure of event memory and to other researchers who, for a variety of reasons, rely on the accuracy of people's temporal estimates. Over 2,000 subjects were asked to say when two major news events, Thatcher's resignation and the Hillsborough football disaster, happened. By embedding the questions in a face-to-face survey we hoped to maximize the probability of subjects using a relatively simple estimation heuristic, previously described as the accessibility principle. This predicts that underestimation of elapsed time should be associated with clearer memories. This hypothesis was not corroborated. We discuss which aspects of the accessibility principle can be retained. © 1997 by John Wiley & Sons, Ltd. 相似文献

For many years psychologists have conducted carefully balanced and controlled experiments in order to understand the processes involved with line-up identifications. While the results are useful, several researchers have questioned whether these experiments are applicable to real line-ups. In this study we compare the results from two specialist line-up suites with the results from ordinary police stations. Witnesses at the suites chose foils more often than witnesses at the police stations. However, characteristics of the crimes, witnesses and suspects at the suites differed from those conducted at the stations. Many of these characteristics are also associated with increased proportions of foils being chosen. For example, the specialist suites tended to accommodate more non-white suspects, more crimes of violence and, at the time of this research, their line-ups occurred longer after the event. Several of the methodological difficulties of using data from real line-ups are discussed and appropriate statistical techniques are introduced. 相似文献

In Experiment 1 neither hearing nor prelingually deaf signing adolescents showed marked lateralization for lexical decision but, unlike the hearing, the deaf were not impaired by the introduction of pseudohomophones. In Experiment 2 semantic categorization produced a left hemisphere advantage in the hearing for words but not pictures whereas in the deaf words and signs but not pictures showed a right hemisphere advantage. In Experiment 3 the lexical decision and semantic categorization findings were confirmed and both groups showed a right hemisphere advantage for a face/nonface decision task. The possible effect of initial language acquisition on the development of hemispheric lateralization for language is discussed. 相似文献

En raison du développement des équipes de travail dans les organisations, on souhaite obtenir des informations sur la meilleure façon de structurer les groupes pour les rendre efficients. Cette étude porte sur la relation de l'expérience de l'autonomie et du travail en équipe, des capacités et des compétences (KSAs) avec la performance du groupe et l'effort émanant de ses membres. Deux modèles ont été mis à l'épreuve à partir d'une recherche théorique et empirique continue. Des données provenant d'un échantillon de 41 équipes de production (174 participants) apportèrent des éléments en faveur du modèle de médiation selon lequel l'autonomie est associée à la perfomance et à l'effort par l'intermédiaire des KSAs. Le modèle alternatif de modération qui suppose que l'autonomie et les KSAs interagissent pour déboucher sur la performance et l'effort ne fut pas corroboré.
Given the increasing use of work teams in organizations, interest exists in identifying the best ways to design teams so that they lead to positive outcomes. This study examined how team autonomy and teamwork knowledge, skills, and abilities (KSAs) relate to team performance and member job strain. Based on extant empirical and theoretical work, two models were tested. findings from a sample of 41 production teams (174 team members) showed support for the mediation model—that autonomy is associated with performance and strain through teamwork KSAs. The alternative moderation model, suggesting that autonomy and teamwork KSAs interact in predicting performance and strain, was not supported. 相似文献

OBJECTIVE: To examine the cross-sectional association between hostility and pulmonary function (PF) and its consistency across race/ethnicity-gender groups. DESIGN: Data were from the Coronary Artery Risk Development in (Young) Adults (CARDIA) cohort study (N=4,629). Participants were recruited from 4 metropolitan areas in the United States, ages 18-30 years at baseline in 1985-1986, approximately balanced across race/ethnicity (Black, White) and gender. MAIN OUTCOME MEASURES: Main outcome measures were percent predicted values for forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC). RESULTS: In full-sample multiple linear regression analyses, each 1 standard deviation (SD) increase in hostility was associated with a 0.66% decrease in FEV-sub-1 (p=.0002) and a 0.60% decrease in FVC (p=.0006). This inverse association of hostility with PF remained after controlling for age, height, current socioeconomic status (SES), participant smoking status, and asthma and is more consistent than that of smoking and PF. In stratified analyses, each 1 SD increase in hostility predicted statistically significant reductions in PF for Black women, White women, and Black men. For White men, hostility showed no statistically significant relation with PF, although the pattern relating hostility to PF was similar to the pattern in the other three groups. Further, both of the post hoc three-way interaction terms for hostility, race/ethnicity, and gender predicting FEV-sub-1 and FVC were nonsignificant. CONCLUSION: PF was inversely associated with hostility across race/ethnicity and gender, independent of age, height, current SES, smoking, and asthma. On the basis of these cross-sectional findings, the authors hypothesize that higher hostility will predict a more rapid decline in PF. 相似文献
