Is flanker-based inhibition related to age? Identifying specific influences of individual differences on neurocognitive variables

Researchers frequently attempt to identify the specific neurocognitive processes that might be responsible for differences in performance associated with neurological status or other individual difference characteristics by administering two or more conditions of an experimental task to different groups of participants, and focusing on the group-by-condition interaction as the primary outcome of interest. Three limitations of this approach are discussed, and an alternative analytical method is proposed to overcome the limitations. The method is demonstrated in analyses of data from 10 cognitive tasks in two independent studies, including two flanker tasks which are often used to assess aspects of inhibition.     

Do specific types of networking predict specific mobility outcomes? A two-year prospective study

Previous research has established a general relation between networking and career outcomes, as postulated by theories on protean careers and career self management. We suggest that specific facets of networking behavior differentially affect specific career mobility outcomes over time. In a 2-year prospective study, we examined the impact of six facets of networking on the likelihood receiving a promotion, changing employer, or remaining in the current position. Results show that internal networking is related to promotions and change of employer, whereas external networking is only related to change of employer. Moreover, internal networking shows a differential relation with the temporal proximity of promotions where using internal contacts predicts promotions in the first year and building and maintaining internal contacts predict promotions in the second year. However, this temporal pattern did not hold for external networking, where only maintaining external contacts predicted change of employer in the second year.     

工作记忆广度对语篇理解中重读效应的影响

本文探索了工作记忆容量对语篇理解中重读效应的影响。采用阅读广度测验对工作记忆容量进行测量, 筛选出高、低广度两组被试。并采用听觉动窗实验范式, 比较两组被试在语篇理解中即时加工时间的差异。研究结果表明, 重读效应受到工作记忆广度的显著影响。对于低工作记忆广度被试, 一致性重读促进语篇理解, 不一致性重读阻碍语篇理解; 但对于高工作记忆广度被试, 一致性重读的促进效应和不一致性重读的阻碍效应都不显著。另外, 只有在不一致性重读条件下, 低广度者语篇理解的即时加工时间显著多于高广度者, 而在一致性重读和无重读条件下则没有显著差异。最后用工作记忆的控制性注意理论对研究结果进行了讨论。     

阶层流动的“双刃剑”效应及其心理机制

阶层流动是指人们在社会分层体系中相对位置的变化。人们普遍预期,向上流动促进个体发展和社会进步。然而近期研究也表明,向上流动还可能损害个体健康和主观幸福感,使人们低估和容忍社会不平等,并反对再分配。地位认同、贫富归因倾向以及系统公正信念能够解释向上流动的双刃剑效应。未来研究需要进一步澄清向上流动感知的具体表现,深入考察向上流动影响的心理机制,探索促进阶层流动积极效应发挥的干预方法。

Social Identity and Spatial Behaviour: The Relationship between National Category Salience, the Sense of Home, and Labour Mobility across National Boundaries

This study explores the impact of manipulating the salience of national categories upon the willingness of highly identifying Scots to take up either short-term or long-term jobs in Scotland as compared to England. The results support the hypotheses (a) that high-identifying Scots increase preference for intra- over extranational locations when national categories are salient, (b) that this effect is fully mediated by "fitting in"—that is, the sense of being "at home" in Scottish as compared to English locations, and (c) that these relationships only hold for long-term as opposed to short-term jobs. We discuss these results in terms of the impact of identity definitions upon spatialised action and the economic/political importance of this relationship.     

Development and validation of the General Risk Propensity Scale (GRiPS)

Despite the widespread interest in understanding and identifying risk takers by psychologists, clinicians, and economists, the risk literature currently lacks consensus regarding the nature of risk taking and its measurement. Existing measures of risk taking are predominantly domain‐specific despite emerging support for risk taking as a domain‐general disposition. In the present paper, we examine the nature of risk taking as a domain‐general personality disposition and develop a concise measure: the General Risk Propensity Scale (GRiPS). Data from 1,523 participants across five studies provided evidence for its construct validity. The GRiPS converged with other self‐report measures of risk taking and provided incremental prediction of work, academic, and life outcomes over and above the five‐factor model of personality and the Domain‐Specific Risk Taking Scale.     

The loss‐bet paradox: Actuaries,accountants, and other numerate people rate numerically inferior gambles as superior

Psychologists have convincingly demonstrated that preferences are not always stable and, instead, are often “constructed” based on information available in the judgment or decision context. In 4 studies with experts (accountants and actuaries in Studies 1 and 2, respectively) and a diverse lay population (Studies 3 and 4), the evidence was consistent with the highly numerate being more likely than the less numerate to construct their preferences by rating a numerically inferior bet as superior (i.e., the bets effect). Thus, the effect generalizes beyond a college student sample, and preference construction differs by numeracy. Contrary to prior thinking about preference construction, however, high expertise and high ability (rather than low) consistently related to the paradoxical phenomenon. Results across studies including Study 3's experimental modifications of the task supported the hypothesized number comparison process (and not a lack of expertise with monetary outcomes and probabilities or numeracy‐related differences in attention to numbers) as the effect's underlying cause. The bets effect was not attenuated by Study 4's instructions to think about what would be purchased with bet winnings. Task results combined with free‐response coding supported the notion that highly numerate participants have a systematic and persistent inclination for doing simple and complex number operations that drive their judgments (even after controlling for nonnumeric intelligence). Implications for 3 types of dual‐process theories are discussed. The results were inconsistent with default‐interventionist theories, consistent or unclear with respect to fuzzy trace theory, and consistent with interactive theories.     

Age differences in moral judgment: Older adults are more deontological than younger adults

In 2 studies, an older and a younger age group morally evaluated dilemmas contrasting a deontological judgment (do not harm others) against a utilitarian judgment (do what is best for the majority). Previous research suggests that deontological moral judgments are often underpinned by affective reactions and utilitarian moral judgments by deliberative thinking. Separately, research on the psychology of aging has shown that affect plays a more prominent role in the judgments and decision making of older (vs. younger) adults. Yet age remains a largely overlooked factor in moral judgment research. Here, we therefore investigated whether older adults would make more deontological judgments on the basis of experiencing different affective reactions to moral dilemmas as compared with younger adults. Results from 2 experiments indicated that older adults made significantly more deontological moral judgments. Mediation analyses revealed that the relationship between age and making more deontological moral judgments is partly explained by older adults exhibiting significantly more negative affective reactions and having more morally idealistic beliefs as compared with younger adults.     

关系流动性、拒绝敏感性与主观幸福感的关系

为了从社会生态学的视角探讨预测主观幸福感的相关因素、考察拒绝敏感性在其中的中介作用、揭示高关系流动的社会环境对心理健康可能的积极作用,以生活满意度和心理幸福感等为测量工具,对成人进行了研究。研究结果显示:关系流动性可显著正向预测主观幸福感; 拒绝敏感性在关系流动性与主观幸福感之间起中介作用。研究结果表明,高关系流动性能预测个体的低拒绝敏感性,进而预测更高的主观幸福感。
