Remembering to do something in the future (termed prospective memory) is distinguished from remembering information from the past (retrospective memory). Because prospective memory requires strong self-initiation, Craik (1986) predicted that age decrements should be larger in prospective than retrospective memory tasks. The aim of the present study was to assess Craik's prediction by examining the onset of age decline in two retrospective and three prospective memory tasks in the samples of young (18-30 years), young-old (61-70 years), and old-old (71-80 years) participants recruited from the local community. Results showed that although the magnitude of age effects varied across the laboratory prospective memory tasks, they were smaller than age effects in a simple three-item free recall task. Moreover, while reliable age decrements in both retrospective memory tasks of recognition and free recall were already present in the young-old group, in laboratory tasks of prospective memory they were mostly present in the old-old group only. In addition, older participants were more likely to report a retrospective than prospective memory failure as their most recent memory lapse, while the opposite pattern was present in young participants. Taken together, these findings highlight the theoretical importance of distinguishing effects of ageing on prospective and retrospective memory, and support and extend the results of a recent meta-analysis by Henry, MacLeod, Phillips, and Crawford (2004). 相似文献

This article shifts the focus of prior research examining virtual work to investigate how supervisors who work virtually use subordinate performance information. Drawing insights from several research streams, in Study 1, we propose that supervisors who work virtually bias performance ratings in the direction of information that is observed directly in the office, rather than that which is received when working virtually. In Study 2, we replicate and extend these results to show that this bias is independent of the level of performance information received. Results also indicate that, for high-performing workers, performance information received virtually is evaluated more extremely than information observed directly. We did not find evidence for this extremity effect when low-performing workers were evaluated. 相似文献

The question why synaesthesia, an atypical binding within or between modalities, occurs is both enduring and important. Two explanations have been provided: (1) a congenital explanation: we are all born as synaesthetes but most of us subsequently lose the experience due to brain development; (2) a learning explanation: synaesthesia is related to some learning process during childhood. Three recent studies provide conflicting support for these explanations. Two studies supported the idea that synaesthesia is learned by showing that the frequency of everyday language implicitly modulates the synaesthetic experience. Another study argued that synaesthesia reflects basic, innate magnitude representations. In this paper we reassess these points of view, and show that it is possible for both to be valid. These findings are integrated into an interactive specialization account of development in order to explain the neuronal mechanism underlying synaesthesia. 相似文献

Although the stigmatization of obesity among children is highly prevalent, its origins and relationship to mass media exposure are largely unknown. Ninety boys and 171 girls aged 10–13 years (mean BMI = 19.84) were asked to rank, in order of liking, 12 figures of peers depicted both with and without various disabilities or obesity, and to rate their attitudes towards the obese child on visual analogue scales. Weekly time spent watching television, watching videogames, and reading magazines on weekdays and weekends was assessed. Total media use, magazine use, and videogame use were significantly correlated with more negative reactions to obese girls and boys. Regression analyses revealed that greater dislike of obese children relative to their non-overweight peers was uniquely predicted by magazine reading time. Thus, media exposure was associated with stigmatizing attitudes towards obese children. Mass media sources may lead children to devalue and stigmatize peers with above-average body weights. 相似文献

The feeling that we are agents, intentionally making things happen by our own actions, is foundational to our understanding of ourselves as humans. People's metacognitions of agency were investigated in 4 experiments. Participants played a game in which they tried to touch downward scrolling Xs and avoid touching Os. Variables that affected accuracy included speed of the scroll, density of the targets, and feedback. Of central interest were variables directed not only at accuracy but also at people's control: the turbulence of the cursor and how close the cursor had to come to the target for a hit (i.e., "magic"). After each trial, people made judgments of agency or judgments of performance. People were selectively sensitive to the variables to which they should be responsive in agency monitoring--whether the cursor moved in close synchrony to their movements and whether targets disappeared by magic. People knew, separably from their objective or judged performance, when they were in control and when they were not. These results indicate that people can sensitively monitor their own agency. 相似文献

A community-based sample of disadvantaged African American women (n = 445) was recruited to participate in 1 of 3 theoretically driven experimental interventions based on either the theory of gender and power, social learning theory, or cognitive behavioral theory. Intervention outcomes were compared with a waiting list control condition. From baseline to postintervention, women in the experimental interventions showed differential change on cognitive indices (knowledge and attitudes) and skill acquisition (partner negotiation skills, correct condom application, lubricant selection, and information-provision to social networks) whereas control participants were unchanged. Women in the 3 experimental interventions also completed follow-up assessments for 1 year following the interventions. In all 3 experimental conditions, condom use increased relative to the control group and there were no differences between the experimental interventions. Women who participated in one of the theoretically grounded interventions continued to increase condom use over the following year. Women entering new relationships reported significantly more condom use than did women who remained in ongoing relationships. The findings suggest that intervention models that have proven effective for women who engage in high-risk behavior may be less effective for women in established relationships for whom risk is primarily derived from the extrarelationship behavior of their partners. 相似文献

A social-cognitive model of physical activity was tested, using structural equation analysis of data from 999 adults (21% African American; 66% female; 38% inactive) recruited from 14 southwestern Virginia churches participating in the baseline phase of a health promotion study. Within the model, age, race, social support, self-efficacy, and self-regulation contributed to participants' physical activity levels, but outcome expectations did not. Of the social-cognitive variables, self-regulation exerted the strongest effect on physical activity. Independent of self-regulation, self-efficacy had little effect. Social support influenced physical activity as a direct precursor to self-efficacy and self-regulation. The model provided a good fit to the data and explained 46% of the variance in physical activity among the diverse group of adults. 相似文献
