The present study investigated whether people can combine two memory strategies to encode pairs of words more efficiently than with a single strategy, and age-related differences in such strategy combination. Young and older adults were asked to encode pairs of words (e.g., satellite-tunnel). For each item, participants were told to use either the interactive-imagery strategy (e.g., mentally visualising the two words and making them interact), the sentence-generation strategy (i.e., generate a sentence linking the two words), or with strategy combination (i.e., generating a sentence while mentally visualising it). Participants obtained better recall performance on items encoded with strategy combination than on items encoded with interactive-imagery or sentence-generation strategies. Moreover, we found age-related decline in such strategy combination. These findings have important implications to further our understanding of execution of memory strategies, and suggest that strategy combination occurs in a variety of cognitive domains. 相似文献

Whether older adults can compensate for their associative memory deficit by using memory strategies efficiently might depend on their general cognitive abilities. This study examined the moderating role of an IQ estimate on the beneficial effects of strategy instructions. A total of 142 participants (aged 18–85 years) received either intentional learning or strategy (“sentence generation”) instructions during encoding of word pairs. Whereas young adults with a lower IQ benefited from strategy instructions, those with a higher IQ did not, presumably because they already use strategies spontaneously. Older adults showed the opposite effect: following strategy instructions, older adults with a higher IQ showed a strong increase in memory performance (approximately achieving the level of younger adults), whereas older adults with a lower IQ did not, suggesting that they have difficulties implementing the provided strategies. These results highlight the importance of the role of IQ in compensating for the aging-related memory decline. 相似文献

采用2×3组间设计, 检测特质应对(积极与消极)与展现规则(积极、消极、无规则)对情绪劳动的影响。结果表明, 积极应对引起更多深层动作; 积极规则下出现较少表层扮演(与消极应对比)。积极和消极规则都引起较多深层和表层动作。积极应对在积极规则下表层扮演较少(与消极规则比); 消极应对在积极规则下表层扮演较多(与消极规则比)。研究提示, 特质情绪性可能是调节展现规则与情绪劳动关系的重要原因。 相似文献

影响决策的情感因素——后悔理论的研究述评 总被引:2,自引:0,他引:2
情感因素在决策中起着重要的作用。本文对决策中最重要的情感因素——后悔因素的研究发展及其成果做了归纳总结,同时也将一些零散的发现整合在一起,使之更加系统化。后悔情绪对决策的影响作用不容忽视,作为决策理论之一的后悔理论在决策理论中的重要地位日益凸显出来。未来的研究将仍旧主要集中在其对决策的影响方面。后悔理论成为理性决策的一个可替代理论,已为时不远。 相似文献

The recognition heuristic (RH) claims that people base inferences on recognition only. This has been questioned by several studies which found that additional knowledge was influential. However, in some of these studies, participants' additional knowledge might have encompassed criterion knowledge thus rendering any inferential strategy superfluous. The present study was therefore designed to test the effect of criterion knowledge on use or non‐use of the RH. Eighty‐one participants made pair‐wise comparisons with respect to the size of Belgian cities and also provided estimates of the cities' actual size. We found that relative criterion knowledge (i.e., knowledge about the relative position of an object on the criterion dimension) did indeed play some role, but its exclusion left the main critical findings intact, nonetheless. We thus conclude that previous studies conducted in the paradigm of natural recognition should not be generally refuted by the argument of participants possessing criterion knowledge.

Previous research has shown that positive affect (PA) is associated with the coping strategies of "searching for and finding positive meaning." The purpose of this study was to investigate the relationship between the coping strategy of "finding positive meaning" and PA using an intervention method. Additionally, inasmuch as previous research has revealed that PA is associated with physical and mental health status, the current study measured health status in order to carry out a preliminary test as to whether PA increased by the intervention can also improve health. Participants in the intervention group (Japanese graduate students; 13 men and 16 women) reported the most stressful event during the past 3 days and its positive meaning, while those in the control group (13 men and 15 women) reported the most stressful event alone. Both groups reported twice a week for 5 successive weeks using e-mails. Three questionnaires, the Japanese version of the Positive and Negative Affect Schedule scales for measuring positive and negative affects (NA), the situational version of the General Coping Questionnaire for coping strategies, and the Japanese version of the General Health Questionnaire for health status, were administered to all participants just before the start of the intervention, after the conclusion of the intervention, and at the 5-week follow-up session. Results revealed that the "finding positive meaning" coping strategy and PA were enhanced by the intervention in the follow-up for men and women with no changes in NA. For the health scales of the General Health Questionnaire, no significant group-related effects were observed. Thus, the intervention had no significant influence on NA or health status. Implications of these findings for future research are discussed along with a few limitations in this study. 相似文献
