Contrary to popular belief many choice options and the ability to reverse one's initial choice are sometimes associated with decreased chooser satisfaction. Two studies investigated the role of counterfactual thinking in explaining these paradoxes. Participants chose drawing implements from either a limited (6) or extensive (24) choice set (Study 1), or an expected reversible/non-reversible selection (Study 2). Following a drawing task, satisfaction with their chosen implement was rated under either high or low cognitive load to manipulate the availability of counterfactual alternatives. In Study 1 satisfaction was higher with limited vs. extensive choice under low load. The number of counterfactuals generated mediated this effect. Under high load the pattern was reversed. Participants in Study 2 generated more counterfactuals when reversibility was expected under low but not high load and this partially mediated the impact of expected reversibility on revealed satisfaction. Implications for theoretical understanding of these paradoxes are discussed.  相似文献

American universities increasingly admit first-generation college students whose parents do not have 4-year degrees. Once admitted, these students tend to struggle academically, compared with continuing-generation students--students who have at least 1 parent with a 4-year degree. We propose a cultural mismatch theory that identifies 1 important source of this social class achievement gap. Four studies test the hypothesis that first-generation students underperform because interdependent norms from their mostly working-class backgrounds constitute a mismatch with middle-class independent norms prevalent in universities. First, assessing university cultural norms, surveys of university administrators revealed that American universities focus primarily on norms of independence. Second, identifying the hypothesized cultural mismatch, a longitudinal survey revealed that universities' focus on independence does not match first-generation students' relatively interdependent motives for attending college and that this cultural mismatch is associated with lower grades. Finally, 2 experiments at both private and public universities created a match or mismatch for first-generation students and examined the performance consequences. Together these studies revealed that representing the university culture in terms of independence (i.e., paving one's own paths) rendered academic tasks difficult and, thereby, undermined first-generation students' performance. Conversely, representing the university culture in terms of interdependence (i.e., being part of a community) reduced this sense of difficulty and eliminated the performance gap without adverse consequences for continuing-generation students. These studies address the urgent need to recognize cultural obstacles that contribute to the social class achievement gap and to develop interventions to address them.  相似文献

We propose that guilt proneness is a critical characteristic of leaders and find support for this hypothesis across 3 studies. Participants in the first study rated a set of guilt-prone behaviors as more indicative of leadership potential than a set of less guilt-prone behaviors. In a follow-up study, guilt-prone participants in a leaderless group task engaged in more leadership behaviors than did less guilt-prone participants. In a third, and final, study, we move to the field and analyze 360° feedback from a group of young managers working in a range of industries. The results indicate that highly guilt-prone individuals were rated as more capable leaders than less guilt-prone individuals and that a sense of responsibility for others underlies the positive relationship between guilt proneness and leadership evaluations.  相似文献

Although hundreds of dialogue programs geared towards conflict resolution are offered every year, there have been few scientific studies of their effectiveness. Across 2 studies we examined the effect of controlled, dyadic interactions on attitudes towards the ‘other’ in members of groups involved in ideological conflict. Study 1 involved Mexican immigrants and White Americans in Arizona, and Study 2 involved Israelis and Palestinians in the Middle East. Cross-group dyads interacted via video and text in a brief, structured, face-to-face exchange: one person was assigned to write about the difficulties of life in their society (‘perspective-giving’), and the second person was assigned to accurately summarize the statement of the first person (‘perspective-taking’). Positive changes in attitudes towards the outgroup were greater for Mexican immigrants and Palestinians after perspective-giving and for White Americans and Israelis after perspective-taking. For Palestinians, perspective-giving to an Israeli effectively changed attitudes towards Israelis, while a control condition in which they wrote an essay on the same topic without interacting had no effect on attitudes, illustrating the critical role of being heard. Thus, the effects of dialogue for conflict resolution depend on an interaction between dialogue condition and participants' group membership, which may reflect power asymmetries.  相似文献

Three studies examined how endorsement of self‐discovery and self‐creation metaphors influences belief in the true self and its use as meaning source. It was hypothesized that discovery metaphors contribute to belief in the true self and bolster the relationship between true self‐knowledge and meaning. Study 1 supported the hypothesis that discovery is positively associated with belief in the true self among a sample of college students (N = 311). Studies 2 and 3 extended the analysis by showing that the discovery metaphor also facilitates perceptions of meaning and the use of the true self specifically as a source of meaning in a second sample of college students (N = 75) as well as an adult sample of university employees (N = 173). Implications for understanding what enables the true self to infuse life with meaning, as well as an individual differences approach to metaphoric cognition, are discussed.  相似文献

A magnitude effect in human intertemporal choice is well established-larger rewards or outcomes are discounted over time at a lower rate than are smaller rewards. However, many recent studies have failed to find a corresponding effect in nonhuman animals. Here we report a magnitude effect in temporal discounting for pigeons' choices involving a tradeoff between reward delay and amount. Pigeons chose between a small reward (1-s access to food) after a 2-s delay, and a large reward (4.5-s access to food) after a 28-s delay. Across conditions, the delays to the small and large rewards were increased or decreased, respectively. Temporal discounting functions obtained through a value-estimation procedure showed clear evidence of a magnitude effect: The value of the large reward decreased more slowly with increasing delay than the value of the small reward. We linked this result to a nonlinear relationship between choice and the delays associated with the small and large rewards. The nonlinearity was contrary to the generalized matching law but was predicted by the contextual choice model. Our results confirm the existence of a magnitude effect in nonhuman temporal discounting, showing that this adaptation is not unique to humans.  相似文献

The authors propose that competence need fulfillment within valued role domains (i.e., spouse, parent, worker) will account, in part, for associations between autonomy and relatedness need fulfillment and psychological health. Testing these assertions in cross-sectional and longitudinal surveys of women in two independent community samples, the findings are the first to formally examine whether the satisfaction of competence needs within social roles accounts for associations between other types of need satisfaction and affective outcomes as well as depressive symptomology. Evidence supporting the hypothesis was stronger when examining individuals' affective health as compared to their depressive symptoms. Implications of the findings are discussed with regard to need fulfillment within social roles.  相似文献

This study examined how Borderline Personality Disorder (BPD) and its components influence job performance. BPD is theorized to adversely affect the generation of task strategies in the workplace which results in poor job performance. In this study, 180 college students completed the Borderline Scale from the Personality Assessment Inventory (PAI-BOR; Morey, 1991) followed by a work-related simulation. While none of the facets of BPD related to task strategy, the composite of borderline negatively related to task strategy, which was positively related to task performance. Thus, borderline appears to have an indirect effect on task performance through task strategy.  相似文献

This study aimed to evaluate the robustness of the linear mixed model, with the Kenward-Roger correction for degrees of freedom, when implemented in SAS PROC MIXED, using split-plot designs with small sample sizes. A Monte Carlo simulation design involving three groups and four repeated measures was used, assuming an unstructured covariance matrix to generate the data. The study variables were: sphericity, with epsilon values of 0.75 and 0.57; group sizes, equal or unequal; and shape of the distribution. As regards the latter, non-normal distributions were introduced, combining different values of kurtosis in each group. In the case of unbalanced designs, the effect of pairing (positive or negative) the degree of kurtosis with group size was also analysed. The results show that the Kenward-Roger procedure is liberal, particularly for the interaction effect, under certain conditions in which normality is violated. The relationship between the values of kurtosis in the groups and the pairing of kurtosis with group size are found to be relevant variables to take into account when applying this procedure.  相似文献
