The present study tried to specify how much processing speed, working memory capacity, and inhibition capability contribute to the effects of aging on language performance. An individual-differences approach was used to examine the component processes that predict performance in language comprehension and verbal long-term memory tasks. A total of 151 participants aged 31-80 completed language processing tasks and a battery of tasks designed to assess processing speed, working memory, and resistance to interference. Latent-construct structural equation modeling was used to examine the relationships of these factors and age to different types of language tasks. The best fit model showed first that all the significant relationships between age and language performance are mediated through reductions in speed, resistance to interference, and working memory; this confirms the validity of the general factor approach of age-related differences in cognitive performance. The best fit model, however, also showed that the contribution of speed and resistance to interference is indirect and mediated by working memory, which appears to play a crucial role in explaining age-related differences in language performance. 相似文献

The influence of functional social support on executive functioning in middle-aged African Americans

ABSTRACT Social support has a positive influence on cognitive functioning and buffers cognitive decline in older adults. This study examined the relations between social support and executive functioning in middle-aged adults. A community-based sample of African Americans completed the Interpersonal Support Evaluation List, a measure of functions of social support, and two measures of executive functioning, the Stroop Color and Word Test and the Wisconsin Card Sorting Test (WCST). Hierarchical regression analyses were used to explore the hypothesis that different facets of perceived social support influence performance on measures of executive functioning. After controlling for age, gender, and education, social support facets including belonging support, selfesteem support, appraisal support, and tangible support were significant predictors of Stroop performance. In addition, tangible support significantly predicted WCST performance. These findings add to previous literature on social support and cognition; however, findings for middle-aged adults are unique and suggest that social support has a positive influence on some executive functions in African Americans prior to old age. 相似文献

Discrimination towards members of low-status groups takes a variety of forms, and results in a variety of negative consequences for its victims. Furthermore, discrimination may influence its targets either directly (for instance, when housing discrimination makes insurance, mortgage rates, or rents higher for African Americans than for whites) or indirectly, that is via perceptions on the part of the stigmatised. In the latter case the outcomes are caused or amplified by perceptions on the part of the victim that he or she is the target of discrimination. This chapter focuses on current research concerning factors that influence the perception of discrimination and its indirect influence on individuals. We review work from our own lab as well as from the field more broadly, focusing on research that attempts to explain contextual and individual variability in how events that are potentially due to discrimination are initially perceived, subsequently interpreted, and then publicly reported or withheld. 相似文献

This chapter examines the role of leadership in overcoming social dilemmas within groups. First, based on prior theorising and research we present two alternative perspectives on leader endorsement in social dilemmas, an instrumental and a relational perspective. Next, we systematically compare these perspectives in a series of experiments investigating leadership in social dilemmas created within small groups in the laboratory. The results of our studies suggest that when their personal identity is salient, group members more strongly endorse leaders who are perceived to be instrumental in solving the freerider problem. In contrast, when a social identity is salient, members more strongly endorse leaders who fulfil their relational needs. Based on these findings we propose a differential needs model of leader endorsement in social dilemmas. 相似文献

Measured values of human behavior may entail contradictory attributes of wave and particle by analogy with the wave/particle attributes of the electron. 1/f scaling is the wave attribute in this analogy and punctate data points are the particle attribute. One consequence of the wave/particle duality in physics was to elevate measurement to a primary place in physical theory, and one purpose of the present analogy is to likewise elevate measurement to a primary place in psychological theory. Another purpose is to emulate Robert Shaw's creative use of analogies, consistent with the brief quotation that begins this article. 相似文献

ABSTRACTThough many studies of the contemporary Buddhist literature exist, such studies often limit their purview to canonised, ‘high-brow’ authors. In this article, I read Janwillem van de Wetering’s The Japanese Corpse, a detective novel, for how it portrays Zen Buddhism. I show that The Japanese Corpse portrays Zen as non-dualist and amoral: good and bad are arbitrary categories that impede spiritual freedom. Likewise, characters’ identities are fluid, not fixed. The novel shows this by insistently associating Zen with sex and violence, and by the use of dramatic motifs. However, the novel also excludes women, particularly Japanese women, from spiritual attainment, instead essentialising them as the sexual objects of the hard-boiled detective story. As a matrix of conflicting values, The Japanese Corpse thus turns out to be a case study of Buddhist modernism, and of challenges of detective fiction as world literature. 相似文献

Infants of about 5 months of age who have just mastered the ability to reach succeed more frequently in contacting an object when they are seated upright than when they are supine or reclined. That effect of posture disappears in the subsequent months. Whether that effect can be attributed either to insufficient muscular strength or to insufficient control over the mechanically unstable arm was the subject of the present investigation. Kinematics and electromyography (EMG) of reaching movements of 8 sitting and supine infants at 12, 16, and 20 weeks of age were recorded. Maximum levels of shoulder torque as well as kinematic stability measures were similar in both postures. Coactivation levels and the frequency of on-off switching of muscles turned out to be higher in the sitting than in the supine posture. The authors suggest that the difference in reaching behavior resulted from the degree of error in the feedforward control signal that was allowed by the different postures rather than either insufficient muscular strength or insufficient control over the mechanically unstable arm. 相似文献
