When remembering an event, it is important to remember both the features of the event (e.g., a person and an action) and the connections among features (e.g., who performed which action). Emotion often enhances memory for stimulus features, but the relationship between emotion and the binding of features in memory is unclear. Younger and older adults attempted to remember events in which a person performed a negative, positive or neutral action. Memory for the action was enhanced by emotion, but emotion did not enhance the ability of participants to remember which person performed which action. Older adults were more likely than younger adults to make binding errors in which they incorrectly remembered a familiar actor performing a familiar action that had actually been performed by someone else, and this age-related associative deficit was found for both neutral and emotional actions. Emotion not only increased correct recognition of old events for older and younger adults but also increased false recognition of events in which a familiar actor performed a familiar action that had been performed by someone else. Thus, although emotion may enhance memory for the features of an event, it does not increase the accuracy of remembering who performed which action. 相似文献

The perception of cast shadows 总被引:1,自引:0,他引:1
When an object casts its shadow on a background surface, the shadow can be informative about the shape of the object, the shape of the background surface and the spatial arrangement of the object relative to the background. Among all these roles, we found that cast shadows were perceptually most relevant for the recovery of spatial arrangement, especially when the shadow is in motion. This finding is intriguing when one considers the ambiguities in the possible ways that shadow motion can be interpreted. We reasoned that the visual system must use a priori constraints to disambiguate the cast shadow motion. One of these constraints is that the light source is stationary. Though simple, the stationary-light-source constraint supports rich, reliable inferences about the qualitative motions of objects in three dimensions. 相似文献

Financial security (i.e., a person’s sense that they can afford the things they need now and in the foreseeable future) contributes to psychological health and well-being. In the present research, we explored the implications of financial security for perceptions of meaning in life. In Study 1, we found that perceptions of financial insecurity predicted perceptions of meaning in life above and beyond income. Further, income only predicted perceptions of meaning to the extent that it was associated with reduced financial insecurity. In Studies 2 and 3, we found that financial security threats undermined perceptions of meaning in life. Taken together, these studies suggest that maintaining financial security is important for a sense of meaning in life. 相似文献

This research reveals that mugshot viewing accompanied by questions about an action can cause young adults to associate the pictured person and the queried action, leading to later false recollection of having seen that person perform that action. In contrast, mugshot viewing in older adults can lead to vague feelings of familiarity for the pictured person, encouraging older adults to later falsely recognize the pictured person performing any familiar action. Participants viewed events involving actors performing different actions and then were asked verbal questions about which actor had performed each action, with each question accompanied by mugshots of potential “perpetrators” of the action. In a later recognition test, older adults were more likely to falsely recognize a novel conjunction of a familiar actor and action if they had seen a mugshot of that actor, regardless of whether the mugshot had accompanied a question about that action. In contrast, young adults were more likely to falsely recognize a conjunction event only if it involved an actor whose mugshot had accompanied a question about that particular action. This effect remained when the analysis was limited to trials involving actors whose mugshots had not been previously selected, implicating false recollection rather than commitment effects. 相似文献

The strengths and difficulties questionnaire (SDQ) is a frequently used tool for universal screening of pre-schoolers’ behavioural and emotional problems. However, evidence for its concurrent validity is equivocal and has not been tested in a Māori population. We aimed to evaluate the concurrent validity of the strengths and difficulties questionnaire (SDQ) in Māori pre-schoolers (tamariki), aged 4 and 5. We carried out a prospective study of 225 tamariki (46% female) for whom a recent SDQ was available from the New Zealand Ministry of Health’s Before School Check database. A trained nurse carried out a standardised wellbeing and behavioural assessment for these children. Sensitivity, specificity, positive predictive and negative predictive values were calculated, using optimal total difficulty scale threshold values published for the SDQ (parent version SDQ-P; teacher version SDQ-T). Primary outcome: an assessment-based child referral to Child and Adolescent Mental Health Services or to a Paediatric outpatient service. Secondary outcomes: assessment-based parental referral to a parenting programme and combined referral. The optimal thresholds for child referral were low for the SDQ-P (13) and SDQ-T (7). Child referral SDQ-P: sensitivity 62%, specificity 83%, positive predictive value 0.35, negative predictive value 0.94. Child referral SDQ-T: sensitivity 77%, specificity 78%, positive predictive value 0.31, negative predictive value 0.96. The findings demonstrate optimal threshold values for referral for Māori on the SDQ-P and SDQ-T are much lower when compared to published thresholds (17 vs. 16). Sensitivity values were also low. A surveillance approach for the assessment of psychosocial problems is recommended for pre-schoolers. 相似文献
