Compared to Dematerialized Money,Cash Increases Impatience in Intertemporal Choice

When it comes to trading time for money (or vice versa), people tend to be impatient and myopic. Often dramatically so. For illustration, half of people would rather collect $15 now than $30 in 3 months. This willingness to forego 50% of the reward to skip a 3‐month wait corresponds to an annual discount rate of 277%. This article investigates how money's physical form biases intertemporal choice. We ask, what happens to (im)patience (i.e., discount rates) when time is traded against cash rather than against an equivalent sum of dematerialized money? We find that intertemporal decisions pitting time against cash (rather than against dematerialized money) increase impatience. The underlying mechanism relates to the pain of parting from money. Letting go of cash (dematerialized money) we can have now is psychologically more (less) painful, which in turn reduces (increases) our willingness to wait for larger‐later payoffs. Importantly, heightening prevention focus (i.e., concerns for safety and security) moderates this bias. The article concludes by discussing the implications of the research, particularly for the psychology of saving behavior.     

Acute effects of exercise on women with pre-existing body image concerns: A test of potential mediators

The primary purpose of this study was to propose and test a mediation model of changes in physical self-efficacy, physical self-perceptions, and affect as mediators by which a single bout of exercise improves state body image. A secondary purpose was to identify how long improvements in state body image are sustained post-exercise. Sixty university-aged women (19.57 ± 1.37 y) with pre-existing body image concerns, and who exercised regularly, were randomized to perform 30 min of moderate-to-vigorous intensity exercise or quiet reading. State body image, physical self-efficacy, physical self-perceptions and affect were assessed. Mediational analyses revealed self-perceptions of body fatness (95% CI [0.03, 0.44], κ² = 0.13, ab_ps = 0.20) and strength (95% CI [0.15, 0.60], κ² = 0.23, ab_ps = 0.33) mediated improvements in state body image which were sustained at least 20 min post-exercise. These results contribute to the development of a model explaining the effects of exercise on body image and practical recommendations for the use of exercise to improve body image.     

绿色锻炼的心理效益:身体锻炼与自然环境的融合

绿色锻炼是指在自然绿色环境中进行身体锻炼。已有研究主要采用前后测实验设计,比较不同绿色环境、身体锻炼和个体特征条件下绿色锻炼心理效益的差异,结果显示绿色锻炼、模拟绿色环境均有助于个体获得更多的心理效益。心理进化模型和注意恢复理论认为人对自然环境的选择偏好是产生绿色锻炼心理效益的原因,但尚未有研究证实。我国的相关研究较少,绿色锻炼内在机制、环境污染与绿色锻炼,以及人工模拟绿色环境将是今后研究的热点。     

The analyst: His professional novel1

The psychoanalyst needs to be in touch with a community of colleagues; he needs to feel part of a group with which he can share cognitive tension and therapeutic knowledge. Yet group ties are an aspect we analysts seldom discuss. The author defi nes the analyst's ‘professional novel’ as the emotional vicissitudes with the group that have marked the professional itinerary of every analyst; his relationship with institutions and with theories, and the emotional nuance of these relationships. The analyst's professional novel is the narrative elaboration of his professional autobiography. It is capable of transforming the individual's need to belong and the paths of identifi cation and deidentifi cation. Experience of the oedipal confi guration allows the analyst to begin psychic work aimed at gaining spaces of separateness in his relationship with the group. This passage is marked by the work on mourning that separation involves, but also of mourning implicit in the awareness of the representative limits of our theories. Right from the start of analysis, the patient observes the emotional nuance of the analyst's connection to his group and theories; the patient notices how much this connection is governed by rigid needs to belong, and how much freedom of thought and exploration it allows the analyst. The author uses clinical examples to illustrate these hypotheses.     

行为遗传学研究之新进展

自上世纪80年代以来,行为遗传学取得了长足的进展。在定量遗传学方面,共享环境和非共享环境概念的引入深化了人们对环境作用的认识;对于环境和遗传关系,不仅认识到基因型-环境的交互作用可能存在三种形式,还揭示出遗传对环境测量的影响——基因型-环境的相关。分子遗传学作为新兴的研究途径,目前以寻找基因为主,将来则以认识基因如何工作为重。行为遗传学的发展前景将是定量遗传学和分子遗传学以行为基因组学为中心的整合。     

The mediating role of affective commitment in the relation of the feedback environment to work outcomes

The Feedback Environment, as opposed to the formal performance appraisal process, is comprised of the daily interactions between members of an organization (Steelman, Levy, & Snell, in press). Relations between the feedback environment and work outcome variables such as Organizational Citizenship Behavior (OCB) were examined through the mediating effects of affective commitment. Results indicate that affective commitment mediates the relation between the feedback environment and organizational citizenship behavior, and this mediated relation is stronger for OCBs directed at individuals than directed at the organization as a whole. Conclusions and implications are discussed.
