In 2 experiments we assessed younger and older adults' ability to remember contextual information about an event. Each experiment examined memory for 3 different types of contextual information: (a) perceptual information (e.g., location of an item); (b) conceptual, nonemotional information (e.g., quality of an item); and (c) conceptual, emotional information (e.g., safety of an item). Consistent with a large literature on aging and source memory, younger adults outperformed older adults when the contextual information was perceptual in nature and when it was conceptual, but not emotional. Age differences in source memory were eliminated, however, when participants recalled emotional source information. These findings suggest that emotional information differentially engages older adults, possibly evoking enhanced elaborations and associations. The data are also consistent with a growing literature, suggesting that emotional processing remains stable with age (e.g., Carstensen & Turk-Charles, 1994, 1998; Isaacowitz, Charles, & Carstensen, 2000). 相似文献

The rise in suicide by African Americans in the United States is directly attributable to the dramatic, nearly three-fold increase in suicide rates of African American males. Gibbs (1997) hypothesized high social support, religiosity, and southern residence are protective factors against suicidality for Black people. This hypothesis was tested among 5,125 participants from the National Comorbidity Survey; 299 were African American males. In this study we hypothesized that there would be significantly lower suicidality in the South, and social support and religiosity would mediate this relationship. Our results indicate that Southern region is indeed a significant predictor of suicidal symptoms in African American men, such that suicidal symptoms were lower in the South, but religiosity and social support did not account for this effect. Other potential mediators were also examined. 相似文献

Five preliminary experiments on sighted individuals revealed marked overestimation on an object size-estimation task using a bimanual response. These experiments ruled out the possibility that overestimation was due to the mode of visual presentation (whether two-dimensional or three-dimensional), the input modality (visual or kinesthetic), or the influence of other visual cues. The main experiment then investigated whether these distortions are due to visual experience by using a variant of the same task to test 24 blind and 24 sighted control participants. Remarkably, the sighted control participants overestimated object size, on average, but the blind participants did not. A follow-up experiment demonstrated that visual memory was the primary influence causing the size over-estimations. We conclude that blind individuals are more accurate than sighted individuals in representing the size of familiar objects because they rely on manual representations, which are less influenced by visual experience than are visual memory representations. 相似文献

The present study examined whether therapist access to the Minnesota Multiphasic Personality Inventory (MMPI-2) predicted favorable treatment outcome, above and beyond other assessment measures. A manipulated assessment design was used, in which patients were randomly assigned either to a group in which therapists had access to their MMPI-2 data or to a group without therapist access to such information. Illness severity, improvement ratings, number of sessions attended, and premature termination were indicators of therapy outcome. Results indicated that therapist access to the MMPI-2 data did not add to the prediction of positive treatment outcome beyond that predicted by other measures in this setting. Findings from this initial study suggest that, compared with other resources, perhaps in clinical settings with an emphasis on diagnosis-based and evidence-based treatment, the MMPI-2 may not provide incrementally valid information. However, these effects warrant replication across different settings and samples. Guidelines for future studies are discussed. 相似文献

Little is known about what additional services youth receive while they reside in out-of-home treatment settings. However, such information may be crucial for explaining effectiveness and variation in outcomes for youth in such settings. Our research examines patterns of multi-sector service use for youth in two settings—Therapeutic Foster Care and group homes. Data come from in-person interviews with Treatment Foster Parents and Group Home Staff for a NC state-wide sample of youth with psychiatric disorders and aggressive behavior. Findings indicated high rates of service use by youth in both settings. Analyses indicated significant differences in service types used by youth in each setting, yet similar volume of service use between settings. Clinical and demographic factors did not significantly influence types of services received. Differences in service patterns between the two groups indicated that youth in TFC were more likely to receive community-based, individualized services while youth in group homes were more likely to receive more restrictive services. 相似文献

In Powers of Horror: An Essay on Abjection, Julia Kristeva outlines her theory of abjection as a simultaneous fascination and horror stemming from sensorial reminders of the subject’s primal, psychological relation to the mother. In this essay, I show how these psychological perspectives can potentially result in acts of physical violence, which I call the “abject response.” Applied to literature, a study of the abject response explains why sexually active female characters, such as Nancy, the prostitute, in Oliver Twist, suffer extreme acts of physical violence: not simply because they are sexual, as critics of Victorian domestic ideology most often argue, but rather because their particularly female bodies give them an agency which threatens to destroy the mastery of women on which Victorian male identity is based. Reading Oliver Twist through the lens of Kristeva reveals the ways in which Sikes, Nancy’s murderer, psychically links her sexuality to the fatal potential he perceives in her body. This threatening construction of women’s sexuality derives from an imbalanced focus in the male psyche on the repulsion aspect of abjection, a focus socially inscribed as a threatening power, which is used to justify violent usurpations of the feminine in masculine constructions of gender. 相似文献

Task switching across the life span: effects of age on general and specific switch costs 总被引:5,自引:0,他引:5
The authors investigated age-related changes in executive control using an Internet-based task-switching experiment with 5,271 participants between the ages of 10 and 66 years. Speeded face categorization was required on the basis of gender (G) or emotion (E) in single task blocks (GGG... and EEE...) or switching blocks (GGEEGGEE...). General switch costs, the difference between switching block and single task block performance, decreased during development and then increased approximately linearly from age 18. In contrast, specific switch costs, the difference between switch trial and nonswitch trial performance in the switching block, were more stable across the same age range. These results demonstrate differential age effects in task-switching performance and provide a fine-grained analysis of switch costs from puberty to retirement. 相似文献

In recent years, numerous studies have demonstrated a link between positive and negative feedback seeking by depressed individuals, interpersonal rejection, and depression chronicity. Nonetheless, many of the specific interpersonal patterns underlying these links have yet to be clearly specified. One important lingering question concerns how depressed individuals respond to negative evaluation or feedback from others, because continued negative feedback seeking could place depressed people at risk for further rejection and continuation/exacerbation of depressive symptoms. Two studies were conducted to investigate the influence of negative feedback provisions from others on the feedback seeking behaviors of individuals with depressive symptoms. The results from Study 1 indicated an increased tendency to seek negative feedback among depressive individuals in association with an independent negative evaluation by their college roommates. Using a sample of newlywed couples, Study 2 extended this finding by demonstrating that, when directly provided with negative feedback from their spouses, individuals with depressive symptomatology actively sought further negative feedback, while those without such symptoms did not. Together, the results from these studies suggest that depressed individuals are likely to respond to negative evaluation and feedback from others with behaviors that could place them at risk for further rejection and continuing, if not worsening problems with depression. 相似文献
