How well children remember negative events is not fully understood. Previous research has failed to simultaneously test memory and perceptions of memory for both negative and positive events. Children (n = 38, 7–17 years) recruited from a hospital following accidental injury were tested for their memory of an injury-producing accident (negative event) and a positive event (unexpectedly receiving a $50 gift voucher). Objective accuracy of memory, memory quality characteristics (e.g., how coherently the event was recalled), children’s judgments of their memory (meta-cognitive), and posttraumatic stress (PTS) symptoms were assessed 2 months post-injury. Children’s memories for their experiences were verified using witness/parent reports. Memory quality characteristics of children’s free recollection were coded with a previously used standardized system. Overall, children showed high levels of accuracy for both events, with little degradation over time. High PTS children showed little evidence of deficits in coherence or organization in their narratives relative to low PTS children. Although in some instances high PTS children judged their memory quality to be poor compared to low PTS children, this depended on how this was assessed (e.g., self-report questionnaire vs. coded narratives). In terms of limitations, it is unclear whether the findings will generalize for memories of repeated events. Witness verification of the accident details itself could be prone to error. In conclusion, the findings are broadly supportive of the proposal made by theorists who argue that trauma memories are recalled no less accurately than other distinctive memories. The role of meta-cognitive elements of children’s memory and reporting in PTS is less clear. 相似文献

Effective responder communication,perceived responder legitimacy,and group identification predict public cooperation and compliance in a mass decontamination visualization experiment 下载免费PDF全文

This article describes a visualization experiment that tests hypotheses based on the social identity approach about effectiveness of communication strategies during mass decontamination. Specifically, the mediating role of social identity processes between effective responder communication and relevant outcome variables (e.g., public compliance), is examined. After visualizing that they had been involved in a hypothetical incident involving decontamination, participants (N = 129) received one of three different communication strategies: (1) health‐focused information about decontamination, sufficient practical information; (2) no health‐focused information, sufficient practical information; and (3) no health‐focused information, low practical information. The communication strategy perceived as most effective included health‐focused information and practical information; this resulted in the highest levels of expected compliance, mediated by social identity variables. Implications for management of mass decontamination are discussed. 相似文献

Although discussions of museums often revolve around exhibits, educators in these spaces have the potential to create in-depth, social learning experiences beyond what is possible at exhibits alone. There is still little empirical research, however, to inform how we understand, approach, and improve museum facilitation practices. In this study, we sought to address this gap by quantifying the impact of facilitation by trained educators working with visitors at interactive museum exhibits and comparing this to visitor engagement and learning outcomes for families without educator support. Using a quasi-experimental design, we measured the impact of staff facilitation on visitor engagement time, mathematical reasoning, math awareness, satisfaction, and intergenerational communication across three different exhibits, four trained educators, and two experimental conditions. Multivariate regression modeling showed that staff facilitation had a positive impact on engagement time, mathematical reasoning, and satisfaction, a negative impact on intergenerational communication, and no impact on math awareness. 相似文献

Two experiments are presented that investigate the effects of dynamic visual noise (DVN) on memory for concrete and abstract words. Memory for concrete words is typically superior to that of abstract words and is referred to as the concreteness effect. DVN is a procedure that has been demonstrated to interfere selectively with visual working memory and the generation of images from long-term memory. It was reasoned that if concreteness effects arise because of the ability of the latter to activate visual representations, then DVN should selectively impair memory for concrete words. Experiment 1 found DVN to selectively reduce free recall of concrete words. Experiment 2 investigated recognition memory and found DVN to reduce memory accuracy and remember responses, while increasing know responses to concrete words. 相似文献

The current research considered the effects of gaze direction on a fundamental aspect of social cogition: person memory. It was anticipated that a person's direction of gaze (i.e., direct or averted) would impact his or her subsequent memorability, such that recognition would be enhanced for targets previously displaying direct gaze. In Experiment 1, participants were presented with faces displaying either direct or averted gaze in a person‐classification (i.e., conceptual) task. Then, in a surprise memory test, they were required to report whether a presented face had been seen before. As expected, a recognition advantage was observed for targets displaying direct gaze during the initial classification task. This finding was replicated and extended in a second experiment in which participants initially reported the spatial location (i.e., perceptual task) of each face. We consider the implications of these findings for basic aspects of social‐cognitive functioning and person perception. 相似文献
