Chronic or situational self‐construal moderates the effects of four self‐congruity (SC) dimensions (i.e., actual, ideal, social, and ideal social) on brand evaluations. Past research has mainly focused on the actual and ideal SC effects; these effects have been found to be stronger than the social and ideal social SC effects. However, the findings of past research are based on samples from individualistic cultures. Individualists have a dominant independent self‐construal. We conduct two experiments to show that the social and ideal social SC effects are stronger than the actual and ideal SC effects for individuals with a dominant interdependent self‐construal. In Study 1, using samples from collectivistic cultures, four SC effects are compared. In Study 2, we examine how primed self‐construal, whether independent or interdependent, impacts the four SC effects. This research documents the importance of the social and ideal social dimensions in SC research. 相似文献

ABSTRACT Research in older Caucasians has demonstrated that cognitive activity is related to cognitive function in late adulthood. Knowledge of this association is limited in older minority populations. We examined the relation of cognitive activity and access to cognitive resources, with cognitive function in a group of 108 older African Americans. We constructed two scales to measure the frequency of cognitive activity and the presence of resources that promote cognitive activity during early and late life. Both measures had high internal consistency and the cognitive activity scale had adequate temporal stability over a 4-week interval. In analyses that controlled for age and education, more frequent lifetime cognitive activity was related to current cognitive function, but lifetime cognitive resources only approached significance. The results suggest that both measures are psychometrically sound in a minority population and that lifetime cognitive activity may contribute to current cognitive function in African Americans. 相似文献

Relatively little research has examined the effect of aging upon remote memory, especially among individuals who have entered their 10th decade of life. The present study examined whether remote memory deteriorates in a group of 132 neurologically normal men and women ranging in age from 50 to 97. Remote memory was measured with a modification of the Presidents Test. The data revealed that higher levels of education corresponded with better remote memory. Additionally, age-related differences in memory occurred only in men, with those aged 90 years and older showing significantly worse remote memory than other age groups. Potential explanations and implications of these data are delineated. 相似文献

Feedback-based learning declines with age. Because older adults are generally biased toward positive information (“positivity effect”), learning from positive feedback may be less impaired than learning from negative outcomes. The literature documents mixed results, due possibly to variability between studies in task design. In the current series of studies, we investigated the influence of feedback valence on reinforcement learning in young and older adults. We used nonprobabilistic learning tasks, to more systematically study the effects of feedback magnitude, learning of stimulus–response (S–R) versus stimulus–outcome (S–O) associations, and working-memory capacity. In most experiments, older adults benefitted more from positive than negative feedback, but only with large feedback magnitudes. Positivity effects were pronounced for S–O learning, whereas S–R learning correlated with working-memory capacity in both age groups. These results underline the context dependence of positivity effects in learning and suggest that older adults focus on high gains when these are informative for behavior. 相似文献

ABSTRACT Sex differences in declarative memory and visuospatial ability are robust in cross-sectional studies. The present longitudinal study examined whether sex differences in cognition were present over a 10-year period, and whether age modified the magnitude of sex differences. Tests assessing episodic and semantic memory, and visuospatial ability were administered to 625 nondemented adults (initially aged 35–80 years), participating in the population-based Betula study at two follow-up occasions. There was stability of sex differences across five age groups and over a 10-year period. Women performed at a higher level than men on episodic recall, face and verbal recognition, and semantic fluency, whereas men performed better than women on a task-assessing, visuospatial ability. Sex differences in cognitive functions are stable over a 10-year period and from 35 to 90 years of age. 相似文献

Meaning in life is an important aspect of human well-being and motivation. But as the notion of ‘meaning in life’ is not easily assimilated to that of semantic meaning, it is difficult to define. While meaning in life is standardly discussed in terms of meaningful ways of living, I here take the alternative approach of discussing the meaningfulness of things for agents. I claim that such meaningfulness, or significance, consists in the ways in which things invite agent-relevant responses. Meaningfulness in that sense is important for understanding, not just meaning in life for mature human beings, but also meaning for children, meaning in the arts, the continuity between ‘mere’ living and living meaningfully, and the connection between meaning in life and semantic meaning. 相似文献

This study investigated educator-targeted bullying (ETB) in a South African school setting from a social-ecological perspective. Seven survivors of ETB were interviewed using open ended questions. The data were content analysed for themes. The main findings of the study were: (1) bullies are undisciplined individuals who lack parental support; (2) school and classroom management styles may encourage ETB; and (3) a lack of positive values in the community and a disregard for authority figures perpetuate ETB. Survivors of ETB perceived to lack support from colleagues, school management, and parents of the offending learners. 相似文献
