Overgeneral autobiographical memory (OGM) is a proposed trait-marker for vulnerability to depression, but relatively little work has examined its long-term stability. This study investigated the stability of OGM over several years in 271 late adolescents and young adults participating in a larger longitudinal study of risk for emotional disorders. The Autobiographical Memory Test (AMT) was administered twice, with test–retest intervals ranging from approximately 3 to 6 years. There was evidence of significant but modest stability in OGM over several years. Specifically, Spearman rank correlations (ρs) between the proportions of specific and categoric memories generated on the two AMTs were .31 and .32, respectively. We did not find evidence that the stability of OGM was moderated by the length of the test–retest interval. Furthermore, the stability coefficients for OGM for individuals with and without a lifetime history of major depressive disorder (MDD) were relatively similar in magnitude and not significantly different from one another (ρs=.34 and .42 for the proportions of specific and categoric memories for those with a history of MDD; ρs=.31 for both the proportions of specific and categoric memories for those without a history of MDD). Implications for the conceptualisation of OGM are discussed. 相似文献

Reduced autobiographical memory specificity (AMS) is an important cognitive marker in depression that is typically measured with the Autobiographical Memory Test (AMT; Williams & Broadbent, 1986). The AMT is widely used, but the over-reliance on a single methodology for assessing AMS is a limitation in the field. The current study investigated memory narratives as an alternative measure of AMS in an undergraduate student sample selected for being high or low on a measure of depressive symptoms (N=55). We employed a multi-method design to compare narrative- and AMT-based measures of AMS. Participants generated personally significant self-defining memory narratives, and also completed two versions of the AMT (with and without instructions to retrieve specific memories). Greater AMS in self-defining memory narratives correlated with greater AMS in performance on both versions of the AMT in the full sample, and the patterns of relationships between the different AMS measures were generally similar in low and high dysphoric participants. Furthermore, AMS in self-defining memory narratives was prospectively associated with depressive symptom levels. Specifically, greater AMS in self-defining memory narratives predicted fewer depressive symptoms at a 10-week follow-up over and above baseline symptom levels. Implications for future research and clinical applications are discussed. 相似文献

Diagnosis of Alzheimer's disease (AD) requires evidence of progressive decline in cognitive function. However, many tests used to assess cognitive function suffer from considerable practice effects, reducing their reliability. Several studies have reported that the ability to do two things at once, or dual tasking, is impaired in AD, but unaffected by healthy ageing. The apparent specificity of this impairment suggests that this assessment may be particularly useful in the early diagnosis of AD, but the reliability of this assessment remains unknown. Therefore, this study investigated simultaneous performance of digit recall and tracking tasks across six testing sessions in eight people with AD, eight healthy older adults and eight healthy younger adults. The results found that dual-task performance was unaffected by healthy ageing, but significantly impaired in AD, with no effect of repeated exposure. The absence of any improvements in performance despite increased familiarity with the task's demands suggests that not only is the dual-task assessment well suited for monitoring progression over time, but also that dual tasking involves a specific cognitive function which is impaired in the AD brain. 相似文献

In creativity, there is scant evidence of significant racial and gender differences, and when such differences are found, there is no consistency regarding which groups perform best. There has been little work focusing on racial and gender biases and/or stereotypes within creativity assessment. It is study these issues by using a modified version of the Consensual Assessment Technique in which the judges are provided with information about the creators' gender and/or race. A total of 455 undergraduates assigned ratings for creativity, writing ability, and enjoyment to 60 poems downloaded from a poetry Web site. These poems either had no attribution or had (fictional) stereotypical Black, White, and Crossover names for each gender. Results suggest that novice raters using CAT methodology display little evidence of bias in their ratings of creativity, writing ability, and poem enjoyment. Very slight preference was found for poems assigned names of White females. 相似文献

What role does emotion play in helping youth reach their creative potential? Does it alter how they process ideas, and how many ideas they can generate? By varying the levels of arousal associated with low, medium, and high levels of exertion in the video game Dance Dance Revolution, and inducing a positive or negative mood, this study offers evidence that emotion significantly affects creativity through the interaction of arousal and valence. Faced with the cognitive demand of creativity, lower arousal levels resulted in higher creativity scores when coupled with a negative mood. At high arousal levels, a positive mood resulted in greater creative potential than a negative mood. These results are discussed here in light of theories of emotion as a prime, as information, and as a moderator of attention. 相似文献

An ecological approach to understanding insecure attachments and social isolation among people with an intellectual disability is constructed using Gibson's (1979/1986) affordance-based theory. Although environmental affordances and individual limitations interact to limit the development of social competence, we believe that by focusing on the immediate environment, community-based approaches to helping people with an intellectual disability are often ignored, which increases the burden on individual caregivers. A more comprehensive strategy, which extends Gibson's theory of affordances, allows us to consider how higher level social systems influence the immediate environment and provides the context for understanding why successful change occurs when a multifaceted, holistic approach that works on several levels is adopted. Examining these systems within an ecological framework fundamentally redefines our thinking by shifting the focus from a person's disability to a more nuanced understanding of a person's abilities within the context of appropriate environmental supports in which the person's disability becomes less salient. 相似文献

Media contents that glorify risk-taking (e.g., video games that simulate illegal street racing, TV depictions of dangerous extreme sports or stunts) are becoming increasingly popular. Theory and research suggest that risk glorification is associated with risk-taking among the audience. Until recently the evidence was limited in three ways: First, most studies, being correlational, did not permit clear causal inferences. Second, we did not know the strength of the effect of different types of media and different types of risk-taking outcomes. Third, early research did little to isolate the underlying psychological processes that mediate the pernicious effects of risk glorifying media formats. In order to address these open questions we review the results of an experimental programme of research and the findings of a comprehensive meta-analysis. The main findings are that (a) the risky media contents do indeed have causal force; (b) according to our meta-analysis active participation in risk glorifying media interfaces has a larger effect than passive consumption; (c) psychological processes include the priming of risk-related constructs, effects of risk-positive situational heuristic cues, perceived social norms, personal risk habituation, and changes in the recipient's self-concept. To integrate these findings we propose a theoretical framework derived from broad-range socio-cognitive models. We conclude with a discussion of possible directions for future research. 相似文献

Boundary crossings in academia are rarely addressed by university policy despite the risk of problematic or unethical faculty—student interactions. This study contributes to an understanding of undergraduate college student perceptions of appropriateness of faculty—student nonsexual interactions by investigating the influence of gender and ethnicity on student judgments of the appropriateness of numerous hypothetical interactions. Overall, students deemed the majority of interactions as inappropriate. Female students judged a number of interactions as more inappropriate than did male students, and with a few exceptions, Mexican American and Anglo American students were similar in their ratings of the appropriateness of faculty—student interactions. These findings suggest that universities need to be proactive in establishing guidelines concerning faculty-student boundary crossings. 相似文献
