A major concern in age-related cognitive decline is episodic memory (EM). Previous studies indicate that both resource and binding deficits contribute to EM decline. Environmental support by task manipulations encouraging stronger cognitive effort and deeper levels of processing may facilitate compensation for these two deficits. To clarify factors that can counteract age-related EM decline, we assessed effects of cognitive effort (four levels) and level of processing (LoP, shallow/deep) during encoding on subsequent retrieval. Young (YAs, N?=?23) and older (OAs, N?=?23) adults performed two incidental encoding tasks, deep/semantic and shallow/perceptual. Cognitive effort was manipulated by varying decision-making demands. EM performance, indexed by d-prime, was later tested using a recognition task. Results showed that regardless of LoP, increased cognitive effort caused higher d-primes in both age groups. Compared to YAs, OAs showed a lower d-prime after shallow encoding across all cognitive effort levels, and after deep encoding with low cognitive effort. Deep encoding with higher levels of cognitive effort completely eliminated these age differences. Our findings support an environmental-compensatory account of cognitive ageing and can have important therapeutic implications. 相似文献

Although many studies have investigated the effect of emotion on memory, it is unclear whether the effect of emotion extends to all aspects of an event. In addition, it is poorly understood how effects of emotion on item memory and source memory change over time. This study examined the time course of effects of emotion on item memory and source memory. Participants learned intentionally a list of neutral, positive, and negative Chinese words, which were presented twice, and then took test of free recall, followed by recognition and source memory tests, at one of eight delayed points of time. The main findings are (within the time frame of 2 weeks): (1) Negative emotion enhances free recall, whereas there is only a trend that positive emotion enhances free recall. In addition, negative and positive emotions have different points of time at which their effects on free recall reach the greatest magnitude. (2) Negative emotion reduces recognition, whereas positive emotion has no effect on recognition. (3) Neither positive nor negative emotion has any effect on source memory. The above findings indicate that effect of emotion does not necessarily extend to all aspects of an event and that valence is a critical modulating factor in effect of emotion on item memory. Furthermore, emotion does not affect the time course of item memory and source memory, at least with a time frame of 2 weeks. This study has implications for establishing the theoretical model regarding the effect of emotion on memory. 相似文献

This study examined the roles of 3 multilevel motivational predictors in protégés' personal learning in teams: an autonomy-supportive team climate, mentors' autonomy support, and protégés' autonomy orientation. The authors followed 305 protégés in 58 teams for 12 weeks and found that all 3 predictors were positively related to the protégés' personal learning in teams and that an autonomy-supportive team climate augmented the effects of mentors' autonomy support and protégés' autonomy orientation on protégés' personal learning in teams. Protégés' personal learning in teams mediated the interactive effects of an autonomy-supportive team climate with mentors' autonomy support or protégés' autonomy orientation on protégés' behavioral and attitudinal outcomes, including their organizational citizenship behaviors and job involvement. The findings of this study provide business researchers and practitioners with valuable insights into the management of autonomy. 相似文献

儿童对有关心理特质的自我报告信息的评价 总被引:1,自引:1,他引:0
本研究通过对63名儿童的访谈来调查儿童对他人有关心理特质的自我报告信息的评价。研究发现,10、11岁儿童比6、7岁儿童对高评价性特质“诚实”、“聪明”、“善良”、“友善”自我报告的信息抱有更大的怀疑;但是在中性特质“忧虑”、“喜欢热闹”、“喜欢红色”、“喜欢咸食”上没有显著差异。结果表明,把自我报告作为有关高评价性特质的信息来源时,高年龄组比低年龄组表现出更大的怀疑,而且这种变化是与儿童自我表现能力的提高有关。 相似文献

This research sought to integrate the implicit theory approach and the social identity approach to understanding biases in intergroup judgment. The authors hypothesized that a belief in fixed human character would be associated with negative bias and prejudice against a maligned group regardless of the perceiver's social identity. By contrast, a belief in malleable human character would allow the perceiver's social identity to guide intergroup perception, such that a common ingroup identity that includes the maligned group would be associated with less negative bias and prejudice against the maligned group than would an exclusive identity. To test these hypotheses, a correlational study was conducted in the context of the Hong Kong 1997 political transition to examine Hong Kong Chinese's perceptions of Chinese Mainlanders, and an experimental study was conducted in the United States to examine Asian Americans' perception of African Americans. Results from both studies supported the authors' predictions. 相似文献

幼儿面子谎行为与面子意识研究 总被引:3,自引:0,他引:3
本文研究了幼儿的面子谎行为和面子意识。被试为幼儿园大班幼儿60名(平均年龄5.72岁),中班60名(平均年龄4.74岁),小班40名(平均年龄3.75岁),面子谎行为通过幼儿评画行为测得,而面子意识则通过评价说面子谎故事获得。实验结果表明:大班、中班幼儿明显具有面子谎行为,但两年龄组的幼儿面子谎行为的发生率没有显著差异,小班幼儿没有面子谎行为;幼儿面子意识基本上不存在。说明幼儿面子谎行为的发展远远先于面子意识的形成。 相似文献
