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 We also report new data from two unpublished experiments that are consistent with the BISC model, and we discuss the conditions under which purely behavioral sunk-cost effects are likely to be observed.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

Impulsivity and reward sensitivity are often treated as interchangeable constructs. This conflation may be traced back to Gray’s interpretation of impulsivity as the trait level manifestation of the Behavioral Activation System (BAS), that mediates sensitivity to rewards. In this study (N = 696) we evaluated discriminant hypotheses regarding the relationships between BAS-mediated reward sensitivity, impulsivity and Eysenck’s PEN superfactors. We hypothesized that reward sensitivity would be mainly linked with Extraversion, and that impulsivity would be primarily connected with Psychoticism. Hypotheses were tested using structural equation modelling and equality constraints tests. Results mostly supported our expectations: reward sensitivity was more strongly related to Extraversion than to the other PEN superfactors, while impulsivity was more strongly related to Psychoticism and Neuroticism. Implications for BAS and impulsivity research are discussed. 相似文献

This study addresses self-categorization theory's contention that stereotype content varies as a function of the comparative context within which a given group is considered. A sample of 5-, 7- and 10-year-old children (n = 192) made judgments about gender ingroup behavior in one of two comparative contexts: either adults of the same sex as self or children of the opposite sex. Specifically, judgments were either of the perceived stereotypicality or central tendency of 12 types of behavior. Both types of judgment were found to differ as a function of comparative context in ways predicted by self-categorization theory. However, contrary to prediction, there was no effect of age on the extent of stereotype variability. 相似文献

A history of childhood sexual abuse (CSA) increases the risk of suicidal behavior and the lifetime number of suicide attempts in adults with BPD. Despite a strong association, specific variables mediating the relationship between CSA and adult suicidal behavior in BPD have not been identified. This study examined risk factors for suicidal behavior as potential mediators of the relationship between CSA and suicide attempts in 151 men and women with BPD. Diagnostic, clinical, and psychosocial risk factors, as well as CSA, and suicidal behaviors, were assessed by standardized interviews or self-rated measures. Psychotic and schizotypal symptoms, and poor social adjustment, were associated with both CSA and suicidal behavior, and partially mediated the relationship between CSA and attempter status. Psychotic and schizotypal symptoms in BPD define a vulnerability to cognitive and perceptual distortions under stress. They increase the likelihood of suicidal behavior in BPD, especially in the absence of mitigating social support. A theoretical model for suicidal behavior in BPD is presented which integrates direct, mediated, and moderated pathways between childhood sexual abuse and temperament, adolescent and adult risk factors, and suicidal behavior. 相似文献

We contend that previous work on children's identification with social groups has looked at the mere categorization of the self in group terms and not subjective identification properly conceived. Drawing upon self-categorization theory, the present research operationalizes identification as self-stereotyping (i.e. the ability to conceive of the self in group-relevant terms). Children's self-stereotyping was explored in two studies using gender as the relevant ingroup. Study 1 required 5-, 7- and 10-year-old children, on two separate occasions, to rate their similarity to, and difference from, same-sex peers. Relative to the control condition, when gender had been made salient, children perceived significantly greater similarity, and smaller difference, between themselves and same-sex peers, thus providing evidence of a capacity for self-stereotyping and, hence, for subjective identification with a social category. Similarly, Study 2 sought trait ratings of the self both when gender had been made salient and when it had not. Boys of all ages (though not girls) rated ingroup-stereotypical traits (such as bravery and strength) to be more characteristic of the self when gender was salient than when it was not. Together, these findings suggest that the capacity for subjective identification with social groups is present at least by the age of 5 years. Moreover, they demonstrate that children's self-conceptions are contextually variable. 相似文献

To assess use of imagery intervention in performance of two tennis motor skills the quasi-experimental design included a pre- and posttest and a control group. The tennis service shot and service receiving skill were selected as representative of open and closed skills, respectively. 48 subjects, male tennis players, whose ages ranged from 16 to 18 yr. (M = 17.2), were divided into two groups: (1) Technical practice only which was used as control group and (2) Imagery group who received both imagery and technical practice. Analysis of covariance showed a significant main effect for the imagery intervention on the closed skill (p = .002). Findings suggest that imaging a positive outcome may be more powerful in improving performance of closed skill movements than of open skill movements. 相似文献

Although the sunk-cost effect is a well-documented psychological phenomenon in monetary investments, existing literature investigating behavioral investments (e.g., time, effort) has not replicated this effect except when such investments relate to monetary values. The current explanation for this discrepancy proposes that purely behavioral sunk-cost effects are unlikely to be observed because they are difficult to book, track, and balance in a mental account. Conversely, we argue that, through an effort-justification mechanism, people account for the amount of behavioral resources invested when selecting an alternative, in which case they may fall prey to purely behavioral sunk-cost effects. The results of two experiments support this prediction. Because many decisions involve behavioral investments, behavioral sunk-cost effects should be pervasive psychological phenomena. 相似文献

In this article we strive to provide a detailed and principled analysis of the role of beliefs in goal processing—that is,
the cognitive transition that leads from a mere desire to a proper intention. The resulting model of belief-based goal processing has also relevant consequences for the analysis of intentions, and constitutes the necessary core of a constructive theory of intentions, i.e. a framework that not only analyzes what an intention is, but also explains how it becomes what it is. We discuss similarities
and differences between our approach and other standard accounts of intention, in particular Bratman’s planning theory. The
aim here is to question and refine the conceptual foundations of many theories of intentional action: as a consequence, although
our analysis is not formal in itself, it is ultimately meant to have deep consequences for formal models of intentional agency. 相似文献
