Often, when children testify in court they do so as victims of a repeated offence and must report details of an instance of the offence. One factor that may influence children's ability to succeed in this task concerns the temporal distance between presentations of the repeated event. Indeed, there is a substantial amount of literature on the "spacing effect" that suggests this may be the case. In the current research, we examined the effect of temporal spacing on memory reports for complex autobiographical events. Children participated in one or four play sessions presented at different intervals. Later, children were suggestively questioned, and then participated in a memory test. Superior recall of distributed events (a spacing effect) was found when the delay to test was 1 day (Experiment 1) but there was little evidence for a spacing effect when the delay was 1 week (Experiment 2). Implications for understanding children's recall of repeated autobiographical events are discussed. 相似文献

Faces with expressions (happy, surprise, anger, fear) were presented at study. Memory for facial expressions was tested by
presenting the same faces with neutral expressions and asking participants to determine the expression that had been displayed
at study. In three experiments, happy expressions were remembered better than other expressions. The advantage of a happy
face was observed even when faces were inverted (upside down) and even when the salient perceptual feature (broad grin) was
controlled across conditions. These findings are couched in terms of source monitoring, in which memory for facial expressions
reflects encoding of the dispositional context of a prior event. 相似文献

The present study investigated whether trauma, stress, and discriminatory experiences influenced binge eating among 93 African American and 85 Caucasian women. Trauma and stress were significantly related to binge eating for both groups, although the stress- binge eating relationship was stronger for Caucasian women. Ethnicity did not moderate the relationship between trauma and binge eating, but did moderate the stress-binge eating relationship. Finally, the hypothesis that trauma and stress would influence binge eating through their effects on function of eating was partially supported; the relationship between stress and binge eating was partially mediated by function of eating among Caucasian women. The implications of these findings for our understanding of binge eating are discussed. 相似文献

This study investigated the general benefits and impact that sports activity courses organized by Back-Up, a charitable trust, have on quality of life, mood, self-efficacy and perceived manageability. Participants were 35 community-based individuals with spinal cord injuries (SCI). Questionnaires were completed at the start and end of the course. Fourteen participants also completed the follow-up questionnaire. Questionnaires included demographic questions, the Life Satisfaction Questionnaire, the Hospital Anxiety and Depression Scale, a measure of Perceived Manageability, the Generalised Self-Efficacy Scale and four questions about what participants had gained. Results found that participants' satisfaction with leisure, generalized self-efficacy and motivation to engage in activities was significantly increased between the start and end of the courses and anxiety significantly reduced. Such results were in line with participants' responses relating to overall gains from the course. At both the start and end of the course, higher Perceived Manageability scores correlated with greater self-efficacy and higher Perceived Manageability scores and self-efficacy were correlated with lower depression and anxiety. The study provides evidence of the benefits of sports participation and teamwork for people with SCI, confirming the results of previous research. 相似文献

The proponents of the somatic marker hypothesis presume that rational decision making is guided by emotional reactions that
are developed from prior experience. Supporting evidence for the hypothesis comes almost exclusively from the short-term affective
reactions that are learned during the course of a hypothetical decision-making task—the gambling task (GT). We examined GT
performance and affective reactions to choices when those choices were biased by words that had preexisting affective value.
In one experiment, affectively valued words directly signaled good and bad choices. A congruent relation between affective
value of word and choice outcome improved GT performance, whereas an incongruent relation greatly interfered with performance.
In another experiment, affectively valued words were maintained as a working memory (WM) load between GT choices. A WM load
with affectively positive words somewhat improved GT performance, whereas affectively negative words interfered with performance.
Somatic markers—indicated by differential anticipatory skin conductance response (SCR ) amplitude for good and bad choices—appeared
at a point in the GT session when choice performance was superior. However, differential SCR developed during the session
after good choice performance was already established. These results indicate that preexisting affective biases can influence
GT decision making. In addition, the somatic markers that are regular accompaniments of GT decision making appeared to be
temporally lagging indicators of choice performance. 2006 Psychonomic Society, Inc. 相似文献

Influences of social support and self-esteem on adjustment in early adolescence were investigated in a 2-year longitudinal study (N = 350). Multi-informant data (youth and parent) were used to assess both overall levels and balance in peer- versus adult-oriented sources for social support and self-esteem. Findings obtained using latent growth-curve modeling were consistent with self-esteem mediating effects of social support on both emotional and behavioral adjustment. Lack of balance in social support and self-esteem in the direction of stronger support and esteem from peer-oriented sources predicted greater levels and rates of growth in behavioral problems. Results indicate a need for process-oriented models of social support and self-esteem and sensitivity to patterning of sources for each resource relative to adaptive demands of early adolescence. 相似文献

This paper utilizes a qualitative case study of the health care industry and a recent legal case to demonstrate that stakeholder theory's focus on ethics, without recognition of the effects of incentives, severely limits the theory's ability to provide managerial direction and explain managerial behavior. While ethics provide a basis for stakeholder prioritization, incentives influence whether managerial action is consistent with that prioritization. Our health care examples highlight this and other limitations of stakeholder theory and demonstrate the explanatory and directive power added by the inclusion of the interactive effects of ethics and incentives in stakeholder ordering. 相似文献

The current study examined methods for training teachers to use functional analysis methods. Teachers first received written and verbal instructions detailing attention and demand conditions. They then received training that included modeling, rehearsal, and performance feedback. Finally, probes were taken during ongoing class instruction. Results indicate that teachers acquired the skills and used them in classroom settings. 相似文献

This article examines the applicability of the antidiscrimination provisions of the Americans with Disabilities Act (ADA) of 1990 to The Ticket to Work and Work Incentives Improvement Act (TWWIIA) passed in 1999. Among other policy changes, under the Ticket to Work program, eligible recipients of disability insurance (SSDI) and supplemental income (SSI) receive a voucher or "ticket" to obtain services from qualified employment networks (ENs). ENs provide employment services and supports to designated beneficiaries and must meet certain qualification requirements. The ADA is applicable to ENs in several ways: primarily, in the EN's responsibility to provide appropriate access and services to program participants. This article discusses application of the ADA to the Ticket Program as ENs begin to serve program beneficiaries. 相似文献

Songbirds can learn both to produce and to discriminate between different classes of acoustic stimuli. Varying levels of
auditory discrimination may improve the fitness of individuals in certain ecological and social contexts and, thus, selection
is expected to mold the cognitive abilities of different species according to the potential benefits of acoustic processing.
Although fine-scale auditory discrimination of conspecific songs and calls has been frequently reported for brood parasitic
brown-headed cowbirds (Molothrus ater), it remains unclear why and how they perceive differently the songs of their many host species. Using habituation-dishabituation
paradigms and measuring behavioral and physiological (heart-rate) responses, we found that captive female cowbirds consistently
discriminated between songs of two host species, the song sparrow (Melospiza melodia) and the red-winged blackbird (Agelaius phoeniceus). Playback experiments with stimuli composed of con-specific followed by heterospecific vocalizations in the field also demonstrated
discrimination between these heterospecific songs even though cowbirds were not attracted to playbacks of either host species'
songs alone. Our results do not directly support a nest-searching function of heterospecific song discrimination by cowbirds
and are most consistent with a function of the parasites' avoidance of attacks by their agressive hosts. These data demonstrate
discrimination between heterospecific vocalizations by brown-headed cowbirds and add a novel dimension to the already expansive
auditory perceptual abilities of brood parasitic species and other songbirds.
