Intelligence moderates the benefits of strategy instructions on memory performance: an adult-lifespan examination

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.     

情绪调节脑机制的研究现状与展望

随着脑成像等新技术的运用,关于情绪调节脑机制的研究有了很大进展。近期国外情绪调节脑机制的研究在理论模型上有了新发展;研究关注的情绪调节从有意情绪调节扩展到自动情绪调节;研究针对的情绪、情绪调节策略以及目标群体都有了进一步的扩展和深化;情绪调节脑机制的个体差异研究也有了新进展。本文试图对近期国外情绪调节脑机制研究的发展状况进行梳理,并展望未来研究方向,以期为国内研究提供参考。     

特质应对与展现规则对情绪劳动的影响

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。     

Criterion knowledge: A moderator of using the recognition heuristic?

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.

An intervention study of the effects of the coping strategy of "finding positive meaning" on positive affect and health

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.     

Effects of subcultural differences on country and product evaluations

Most cross‐cultural studies on country of origin or product‐country image (PCI) effects have implicitly assumed that national markets are composed of homogeneous consumers. Although many investigations in this field are described as cross‐cultural, most are in fact cross‐national. The overarching hypothesis of the present research is that PCI effects may vary across subcultures within a country. The results indicate that subcultural differences exist in the evaluation of culturally affiliated countries and their products. Cognitive responses converged to show that consumers' perceived linkages significantly influence the weight given to the country of origin in product evaluations. Several implications for managers and academic researchers are discussed. Copyright © 2003 Henry Stewart Publications.

Remarks on the Absentminded Driver

Piccione and Rubinstein (1997) present and analyse the sequential decision problem of an “absentminded driver”. The driver's absentmindedness (imperfect recall) leads him to time-inconsistent strategy evaluations. His original evaluation gets replaced by a new one under impact of the information that the circumstances have changed, notwithstanding the fact that this change in circumstances has been expected by him all along. The time inconsistency in strategy evaluation suggests that such an agent might have reason to renege on his adopted strategy. As we shall see, however, this danger is only apparent. There is no serious problem of dynamic inconsistency in this case. My diagnosis of the case under consideration is in many respects similar to the one provided by Aumann, Hart and Perry (1997), but the analysis leading to this diagnosis is not quite the same.
