Age‐related differences in delay discounting: Immediate reward,reward magnitude,and social influence

Delay discounting refers to the tendency of individuals to subjectively devalue rewards that are to be received in the future, with high rates of delay discounting being associated with a variety of maladaptive life outcomes (e.g., unhealthy dietary and exercise behaviors). The current study explored the psychological and social processes involved in adult age‐related differences in delay discounting of monetary rewards. Younger adults exhibited higher levels of delay discounting than older adults. This increased level of patience in older adults was found whether smaller‐sooner rewards were to be received immediately or in the future. However, there was an interaction with reward magnitude, whereby younger adults exhibited higher levels of delay discounting for smaller reward magnitudes but not larger reward magnitudes. Social influence on delay discounting was investigated by having participants complete three phases of the delay‐discounting task: an individual precollaboration phase, a collaboration phase in age‐group‐matched dyads, and an individual postcollaboration phase. A convergence effect was observed in that dyad members' postcollaboration choices were significantly more similar compared to their baseline choices during the precollaboration phase. Moreover, levels of convergence were comparable between younger and older adults, suggesting age invariance in social influence on delay discounting. The current results demonstrate a degree of malleability in delay discounting that extends into older adulthood, making interventions targeting the construct a promising avenue for future research.

我国城市居民消费心理预期的结构及其影响因素研究

本研究采用自编《消费心理预期结构问卷》对1097名城市居民进行了研究,结果表明：1《消费心理预期结构问卷》具有较高的信度和效度;2．消费心理预期由预测经历、信息量、价格知觉水平、信息来源与渠道,以及预测依据等5个因素构成;3．现阶段,我国城市居民消费心理预期的一般特点是预期的准确性不高预期的理性化程度尚有待提高;影响消费心理预期结构的主要因素是消费者的性另、年龄、学历、职业和所在城市等变量。     

Effects of Trust in Superiors and Influence of Superiors on the Association Between Individual-Job Congruence and Job Performance/Satisfaction

This research examines the moderating influences of trust in superiors and influence of superiors as elements of an organization communication system on the association between individual-job congruence and job performance/satisfaction. Data from 302 employees were used to assess the research design variables of growth need strength, job scope, trust in superiors, influence of superiors, job performance, and job satisfaction. Moderated regression analysis gave weak support to trust and influence as moderators of the association between individual-job congruence and both job performance and satisfaction. The results did, however, provide justification for trust in superiors and influence of superiors as predictors of performance and satisfaction. The data suggest that other factors may account for changes in the research variables.     

发展性阅读障碍的视听时间敏感性缺陷及其脑神经机制

阅读是一个视听加工过程,阅读障碍的产生可能是过程中视听时间敏感性缺陷的结果。视听时间敏感性指个体对视觉和听觉刺激出现时间的感知能力,可通过同时性判断、时间顺序判断和视听整合考察。研究发现,阅读障碍者在这一能力上表现出行为和脑层面异常。而这些研究多是拼音文字背景,汉语文字下该领域研究相当少。未来需要丰富实验设计,扩大对汉语背景下视听时间敏感性研究,并以此开发干预手段,为阅读障碍的机制和治疗提供借鉴。     

建议采纳的认知机制

决策者的认知特点, 以及决策过程中建议者,任务特征,环境因素等都会影响决策者的认知加工, 并最终影响建议采纳.目前建议采纳过程中的认知研究主要集中于决策者方面, 本文通过总结以往研究, 从决策者的认知风格,社会认知复杂性,认知策略以及情绪对认知的影响等四个方面, 系统阐述了认知对建议采纳的影响.同时, 结合态度改变理论,解释水平理论,具身认知理论以及认知失调理论等进一步讨论了建议采纳的认知发生机制, 并在此基础上初步构建了建议采纳认知机制模型.未来研究可进一步探讨决策者的认知灵活性,认知闭合需要等对建议采纳的影响, 以及建议提出的认知机制, 以丰富建议采纳领域研究.

愉快面孔识别优势及其认知神经机制

愉快面孔识别优势表现为被试对高兴面孔比对其他情绪面孔的识别正确率更高、反应时更短。大量研究以简笔画和面孔图片为材料, 在情绪分类任务和视觉搜索任务中均发现这一优势。该优势存在诊断性价值假说、情绪独特性假说和出现频率假说三种不同的理论解释。近年来, 研究者采用ERP技术发现这一优势形成于反应选择阶段, 但其起始阶段尚无一致结论。未来可借助fMRI技术进一步研究其认知神经机制。
