Previous research suggests that stress can influence a broad range of memory functions. In this study we investigated the effect of a naturalistic stressor, examination stress, on working memory in young adults. In order to accomplish this aim, participants were tested on psychological and hormonal measures of stress and on Digit Span, once during a low stress period and once during a high stress period. The high examination stress condition was associated with an increase in cortisol and subjective impressions of stress. Although Digits Forward performance did not vary with examination stress, Digits Backward performance improved. These findings suggest that mild increases in stress are associated with improvement in the manipulation component of working memory. However, no correlations were found between working memory and either cortisol or psychological stress. Thus the mechanism by which mild naturalistic stressors improve the manipulation component of working memory needs further investigation. 相似文献
Personal growth initiative (PGI) is presumed to foster positive change leading to positive psychological adjustment. Accordingly, in this study we examined PGI as a predictor of life satisfaction 15 weeks later in a sample of 152 Chinese college students. Time 1 PGI was found to explain a significant amount of unique variance in Time 2 life satisfaction, even after controlling for Time 1 life satisfaction and Time 2 PGI. Specifically, (lower) intentional behavior and planfulness at baseline emerged as significant predictors of later life satisfaction. No evidence was found indicating that life satisfaction at Time 1 accounted for any significant amount of unique variance in PGI processes at Time 2, after controlling for baseline PGI processes and concurrent life satisfaction. Overall, the present findings are the first to demonstrate the importance of PGI as a prospective predictor of positive psychological adjustment in adults. 相似文献
This study examined the role played by leisure satisfaction in the relationship between leisure settings (built and natural), subjective well-being, and depression among midlife residents of urban China. Structural equation modeling was used to analyze this conceptual model, exploring data taken from a representative sample of 663 Chinese urban middle-aged citizens included in the 2014 Chinese Leisure Study. Additionally, leisure satisfaction was tested as a mediator between leisure in nature and subjective well-being. The results indicate that leisure satisfaction mediates the relationship between specific leisure settings (i.e., leisure in nature and outdoor recreation), subjective well-being, and depression. The results therefore contribute to the literature by providing evidence of the relationship between leisure settings, subjective well-being, and depression through identification of the positive effects of leisure on nature. Future health interventions should therefore highlight the advantages of urban green spaces.
Because of the expansive multiracial population growth in the United States, the authors explored multiracial identity integration (MII), color‐blind racial ideology (CBRI), and discrimination using regression analyses with 288 individuals. CBRI and discrimination significantly correlated and predicted MII, with 15.3% of the variance explained by discrimination and CBRI. Moderation analysis revealed that CBRI did not moderate the relationship between discrimination and MII. Continued research among multiracial individuals is recommended to better understand the CBRI and racial identity link. 相似文献
The notion that consumers' preference is constructed by decision context is well established. Two of such salient manifestations are compromise effect and attraction effect. Although literature has explored the moderators of these effects from the perspective of a decision maker, little is known about whether a significant difference exists between the effects of individual differences as a situational state and as a stable personality. This article approaches this question by examining how specific self‐confidence and general self‐confidence shape consumer's preference for context options. Four studies find that compromise effect is greater for consumer with high specific self‐confidence, whereas attraction effect is greater for consumer with low specific self‐confidence. The two context effects are greater for consumers with low general self‐confidence only in the presence of social influence. In addition, low (vs. high) general self‐confidence strengthens (vs. weakens) the impact of specific self‐confidence on context effects under this condition. This article concludes by discussing the theoretical and practical implications of the findings. 相似文献
