Flashbulb memories (FMs) are vivid, long-lasting memories for the source of surprising, arousing news. Laboratory studies have consistently found that older adults, especially those with below-average frontal lobe (FL) function, are impaired in source memory relative to young. We tested memory for the source of news concerning the September 11th terrorist attacks in older adults with high or low frontal lobe function and in young people. We found no age differences in source memory a year after the event and no differences related to FL function. Flashbulb memories may be different from usual cases of source memory because of their emotional content, personal importance, or social relevance. 相似文献

In this longitudinal study, the proportion of time preschoolers directed their attention away from rewarding stimuli during a delay-of-gratification task was positively associated with efficiency (greater speed without reduced accuracy) at responding to targets in a go/no-go task more than 10 years later. The overall findings suggest that preschoolers' ability to effectively direct their attention away from tempting aspects of the rewards in a delay-of-gratification task may be a developmental precursor for the ability to perform inhibitory tasks such as the go/no-go task years later. Because performance on the go/no-go task has previously been characterized as involving activation of fronto-striatal regions, the present findings also suggest that performance in the delay-of-gratification task may serve as an early marker of individual differences in the functional integrity of this circuitry. 相似文献

This study investigated the relationship between family support and mental health in a community sample of pregnant women experiencing interpersonal partner violence (IPV). This study also examined how family support may differentially affect mental health in Black and White women experiencing IPV. A total of 110 participants (32 Black and 78 White) were obtained from the first time period of a longitudinal study examining the effects of domestic violence on women. The model was supported (χ2 = 142.55; df = 72, p > .001, RMSEA = .07). Black women had better mental health than White women. However, ethnicity was not a significant predictor of family support. Implications from this study highlight the need for further research on the role of family support in the lives of physically abused women as well as the need to incorporate cross cultural perspectives when examining this issue. 相似文献

The influence of approach and avoidance tendencies on affect, reasoning, and behavior has attracted substantial interest from researchers across various areas of psychology. Currently, frontal electroencephalographic (EEG) asymmetry in favor of left prefrontal regions is assumed to reflect the propensity to respond with approach-related tendencies. To test this hypothesis, we recorded resting EEG in 18 subjects, who separately performed a verbal memory task under three incentive conditions (neutral, reward, and punishment). Using a source-localization technique, we found that higher task-independent alpha2 (10.5-12 Hz) activity within left dorsolateral prefrontal and medial orbitofrontal regions was associated with stronger bias to respond to reward-related cues. Left prefrontal resting activity accounted for 54.8% of the variance in reward bias. These findings not only confirm that frontal EEG asymmetry modulates the propensity to engage in appetitively motivated behavior, but also provide anatomical details about the underlying brain systems. 相似文献

Operant stimulus control applied to maze behavior: heat escape conditioning and discrimination reversal in alligator Mississippiensis 下载免费PDF全文
Eight alligators were trained to escape heat by traversing an 8-ft runway containing right or left approaches to a water tank. All subjects were run until they had satisfied three criteria of stable response time, after which the predominant escape path was blocked, requiring discrimination reversal. Seven subjects again met the criteria; three also met them in a second reversal. 相似文献

It is recognized that parenthood in the context of psychosocial adversity can have negative implications for infant development. Parenting programs are the first line of intervention to improve outcomes for families; however, evidence for the effectiveness of group-based, targeted early interventions is still scarce. Preliminary findings indicate Mellow Babies (MB) as a promising group-based parenting program for families at risk for parenting difficulties. Using thematic analysis, we aimed to understand: (i) the aspects of the intervention that enabled parents to complete the program and (ii) the relational and behavioral changes perceived as valuable for parents and their babies post-intervention. In total, 68 parents residing in the United Kingdom were interviewed after completing MB (49 mothers and 19 fathers; 88% self-identified as British). Three themes and six subthemes were generated from the data. Parents identified several intervention components as beneficial, including the facilitators' interpersonal skills and multi-dimensional, group-based approach. Participant reflections highlighted three underlying mechanisms that enabled positive change: (i) the sense of community cultivated within the group, (ii) the process of formulating and re-conceptualizing one's difficulties, and (iii) the opportunity to reshape interpersonal interactions. Findings are discussed within the context of perinatal and infant mental health. 相似文献

This study examined the levels of depression reported by women who had used a domestic violence shelter. Depressive symptoms were assessed three times: immediately after shelter exit, 10 weeks thereafter, and 6 months later. Whereas 83% of the women reported at least mild depression on the Center for Epidemiological Studies Depression (CES-D) scale upon shelter exit, only 58% were depressed 10 weeks later. This did not change at the 6–month follow-up. An ecological, longitudinal model was evaluated to predict battered women's depression 8/12 months postshelter exit. Results of hierarchical regression analyses suggested that, after controlling for previous levels of depression, the women's feelings of powerlessness, experience of abuse, and decreased social support contributed to their depression symptoms. The women's scores on these three variables (feelings of powerlessness, abuse, and social support) at 10 weeks postshelter exit and at 6-month follow-up predicted depression at 6 months. Thus, there were both predictive and concurrent effects for these constructs. Implications for clinical and community interventions are discussed. 相似文献
