There is growing interest in whether and how sunk-cost effects for purely behavioral investments occur. In this article, we further discuss Cunha and Caldieraro's (2009) Behavioral Investment Sunk Cost (BISC) model and reconcile Otto's (2010) results with the BISC model predictions. We also report new data from two unpublished experiments that are consistent with the BISC model, and we discuss the conditions under which purely behavioral sunk-cost effects are likely to be observed. 相似文献

Women are becoming infected with HIV via heterosexual activity at an accelerating rate, both in the United States and globally. Although a number of evaluations of behavioral risk-reduction interventions for women have been reported, many suffer from methodological problems that weaken confidence in their findings, and furthermore it is clear that many women are unable to respond to the interventions that have been tested. Most women infected through heterosexual activity are infected by their primary partner, yet achieving consistent condom use with this partner can be highly challenging for women. The present article presents recent work and innovative ideas for intervention strategies that may be more feasible, and thus more effective, for women at risk for HIV infection by their primary male partner. 相似文献

合理预期和想象未来事件或场景, 有利于个体做出适应性反应, 促进生存与发展。近年来, 研究者对想象未来的认知加工成分和神经机制进行了深入探讨, 提出了想象未来的相关概念和理论。我们首先概述了想象未来实验常用的思维采样范式和词语-线索范式, 接着介绍了想象未来的自我参照加工、心理场景构建等认知加工成分。此外, 特别介绍了想象未来的默认网络模型以及与之相关的其他大尺度脑网络, 并进一步提出了想象未来的脑网络研究框架。未来的研究可从想象未来的动态脑网络、复杂脑网络以及与疾病的关系等角度入手, 深入探究想象未来的神经机制。 相似文献

利用ERP技术,考察个体的主动性控制在语言转换线索加工阶段的作用。实验采用线索化的语言转换范式,要求汉–英双语者根据线索使用汉语或英语对图片进行命名,记录线索加工阶段的脑电成分。采用AX连续执行测验(AX-Continuous Performance Test)中AY试次的错误率作为主动性控制参与程度的指标。结果发现,在线索呈现后的200-350 ms和350-500 ms两个时间窗口,转换试次比重复试次诱发了更负的N2波幅和晚期负波,而且AY试次的错误率可以显著地预测转换试次的N2和晚期负波的波幅。结果表明,语言转换的线索加工可区分为由主动性控制调节的两个阶段,即“与非目标语言任务图式的分离”和“转入目标语言任务图式”的阶段。本研究为主动性控制参与语言转换过程提供了直接的实验证据。 相似文献

Two studies assessed the predictive validity of implicit political attitudes in relation to voting behavior. In Study 1 , we demonstrated the validity of the adopted measure (i.e., the IAT; Greenwald, McGhee, & Schwartz, 1998 ) with a sample of voters who clearly sided with one of the opposing parties. In Study 2 , implicit political preferences were measured in a sample of undecided voters one month before the election, and actual voting behavior was assessed immediately after the election. Results demonstrated that implicit political attitudes were good predictors of future voting behaviors. These findings support the hypothesis of the presence of embryonic attitudes even in the case of those voters who at the explicit and conscious level deny any preference for one of the two opposing candidates. 相似文献

This study examined to what extent bullying behavior of popular adolescents is responsible for whether bullying is more or
less likely to be accepted or rejected by peers (popularity-norm effect) rather than the behavior of all peers (class norm).
Specifically, the mean level of bullying by the whole class (class norm) was split into behavior of popular adolescents (popularity-norm)
and behavior of non-popular adolescents (non-popularity-norm), and examined in its interaction with individual bullying on
peer acceptance and peer rejection. The data stem from a peer-nominations subsample of TRAILS, a large population-based sample
of adolescent boys and girls (N = 3312). The findings of multilevel regression analyses demonstrated that the negative impact of individual bullying on peer
acceptance and the positive impact on peer rejection were particularly weakened by bullying by popular adolescents. These
results place the class-norm effects found in previous person-group dissimilarity studies in a different light, suggesting
that particularly bullying by popular adolescents is related to the social status attached to bullying.

Survey and behavioral measurements of interpersonal trust 总被引:1,自引:0,他引:1
Although many studies treat trust as a situational construct, individual differences can be used to study and predict trusting behavior. We report two studies, the first showing the psychometric properties of a new trust inventory (the Propensity to Trust Survey or PTS), the second study validating this inventory using the standard economic task, the Investment Game. The first study utilized online survey data (N > 8000) to show that the PTS scales were reliable and measured broad constructs related to Big Five personality domains. Trust was related to extraversion and negative neuroticism, and trustworthiness was related to agreeableness and conscientiousness. The second study (N = 90) validated the PTS trust scale as a predictor of behavior in the Investment Game. These findings are evidence that trust and trustworthiness are compound personality traits, and that PTS scales are preferable to general Big Five measures for predicting trusting behavior. 相似文献

Two experiments were directed at investigating the relationship between response selection and execution in typewriting, and specifically the extent to which concurrent processing takes place. In a Stroop paradigm adapted from [Logan, G. D., & Zbrodoff, N. J. (1998). Stroop-type interference: Congruity effects in colour naming with typewritten responses. Journal of Experimental Psychology: Human Perception and Performance, 24, 978–992], participants typed the names of colour patches with incongruent, congruent, or neutral distractors presented at various stimulus-onset asynchronies. Experiment 1 showed Stroop interference and facilitation for initial keystroke latencies and errors, contrasting with response durations (a measure of response execution) being unaffected by Stroop manipulation. Experiment 2 showed that all three measures were responsive to time pressure; again, Stroop effects were confined to latencies and errors only. The observation that response duration is both flexible under time pressure and protected from response competition, may imply either that response execution is structurally segregated from earlier processing stages, or that encapsulation develops during the acquisition of typing skills. 相似文献

The level of racism in Australia against Aboriginal Australians is well documented. This has an extremely detrimental effect on the health and wellbeing of Aboriginal Australians. One part of the solution may be anti‐prejudice strategies, but to date few strategies that include a pre‐test and a post‐test assessment have been conducted in Australia. The present study describes the interventional qualities of a cultural psychology unit at an Australian university. Results indicated that after a 6‐week period, students reported a significant reduction in prejudice, acceptance of false beliefs about Aboriginal Australians, and the perception that Aboriginal Australians unfairly receive preferential or special treatment. The article concludes that cultural psychology units have the potential to be an effective way of developing acceptance of cross‐cultural differences. 相似文献

Arthur Peacocke was one of the most important scholars to contribute to the modern dialogue on science and religion, and for this he is remembered in the science‐religion community. Many people, however, are unaware of his exceptional career as a biochemist prior to his decision to pursue a life working as a clergyman in the Church of England. His contributions to studies of deoxyribonucleic acid (DNA) structure, effects of radiation damage on DNA, and on the interactions of DNA and proteins are among the most important in the field at the time and have had a lasting scientific impact that is still felt today. Peacocke's arguments with Jacques Monod over stochastic (chance) and deterministic (necessity) processes driving evolution became important independently for both the science and the religion communities and appear to have contributed significantly to his decision to become involved in science‐religion dialogue rather than continuing his work exclusively in the field of science. Nevertheless, although Peacocke took on an active church life and ceased his experimental work, he never left science but continued to read the scientific literature and published a scientific review on different approaches in defining DNA structure as recently as 2005. 相似文献
