The present research uses priming techniques to modify commitment to and engagement in future helping behavior. Relative to a control condition, people primed with the exemplar Superman saw themselves as less likely (Studies 1a and 1b), and participants primed with the category superhero saw themselves as more likely (Study 1a), to help in hypothetical situations. Study 2 extended these effects to real-world planned helping behavior, by demonstrating that these primes impacted commitment to future volunteerism. Finally, Study 3 showed that these changes in initial commitment impacted volunteering behavior up to three months after initial exposure. These results demonstrate that fleeting situational primes can impact not only spontaneous behavior, but also future behavior. 相似文献

The present investigation explores the neural mechanisms underlying the impact of social influence on preferences. We socially tagged symbols as valued or not – by exposing participants to the preferences of their peers – and assessed subsequent brain activity during an incidental processing task in which participants viewed popular, unpopular, and novel symbols. The medial prefrontal cortex (mPFC) differentiated between symbols that were and were not socially tagged – a possible index of normative influence – while aspects of the striatum (the caudate) differentiated between popular and unpopular symbols – a possible index of informational influence. These results suggest that integrating activity in these two brain regions may differentiate objects that have become valued as a result of social influence from those valued for non-social reasons. 相似文献

The Irony of Harmony: Intergroup Contact Can Produce False Expectations for Equality 总被引:1,自引:0,他引:1
ABSTRACT— Positive intergroup contact has been a guiding framework for research on reducing intergroup tension and for interventions aimed at that goal. We propose that beyond improving attitudes toward the out-group, positive contact affects disadvantaged-group members' perceptions of intergroup inequality in ways that can undermine their support for social change toward equality. In Study 1, participants were assigned to either high- or low-power experimental groups and then brought together to discuss either commonalities between the groups or intergroup differences. Commonality-focused contact, relative to difference-focused contact, produced heightened expectations for fair (i.e., egalitarian) out-group behavior among members of disadvantaged groups. These expectations, however, proved unrealistic when compared against the actions of members of the advantaged groups. Participants in Study 2 were Israeli Arabs (a disadvantaged minority) who reported the amount of positive contact they experienced with Jews. More positive intergroup contact was associated with increased perceptions of Jews as fair, which in turn predicted decreased support for social change. Implications for social change are considered. 相似文献

A post-positivist understanding of ecological science and the call for an “ecological ethic” indicate the need for a radically
new approach to evaluating environmental change. The positivist view of science cannot capture the essence of environmental
sciences because the recent work of “reflexive” ecological modelers shows that this requires a reconceptualization of the
way in which values and ecological models interact in scientific process. Reflexive modelers are ecological modelers who believe
it is appropriate for ecologists to examine the motives for their choices in developing models; this self-reflexive approach
opens the door to a new way of integrating values into public discourse and to a more comprehensive approach to evaluating
ecological change. This reflexive building of ecological models is introduced through the transformative simile of Aldo Leopold,
which shows that learning to “think like a mountain” involves a shift in both ecological modeling and in values and responsibility.
An adequate, interdisciplinary approach to ecological valuation, requires a re-framing of the evaluation questions in entirely
new ways, i.e., a review of the current status of interdisciplinary value theory with respect to ecological values reveals
that neither of the widely accepted theories of environmental value—neither economic utilitarianism nor intrinsic value theory
(environmental ethics)—provides a foundation for an ecologically sensitive evaluation process. Thus, a new, ecologically sensitive,
and more comprehensive approach to evaluating ecological change would include an examination of the metaphors that motivate
the models used to describe environmental change.

Research has shown that the perceived morality of the ingroup is a primary source of group pride and ingroup identification. The present research examined whether this is true even when a group has a poor reputation for morality in terms of dishonesty and corruption, such as in the case of Italians. To address this issue, two studies analyzed the role of the three fundamental dimensions of social judgment—morality, competence, and sociability—in predicting Italians’ identification with their nation when the salience of social comparison and the status of the comparison outgroup were varied. Findings showed that perceived morality predicted ingroup identification when participants did not engage in social comparison. Under salient social comparison, individuals based group identification on other dimensions: Perceived sociability was the main predictor of identification when respondents compared with a higher status outgroup (Germans; Study 1; N = 109), whereas perceived competence was the main predictor of identification when participants compared with a lower status outgroup (Romanians; Study 2; N = 121). Overall, findings showed compensation processes in social identification: When social comparison is salient, members of a low morality group base identification on the dimension which allows positive differentiation from the outgroup. 相似文献

Extant research demonstrates that a history of military sexual trauma (MST) is associated with PTSD and depression diagnoses as well as heightened risk for suicidal ideation and death by suicide. Past studies of MST and its sequelae typically collapse harassment-only and assault MST screening items into a single response, recorded as positive or negative for a history of MST. It is presently unclear whether assault is associated with poorer mental health outcomes relative to harassment-only MST. Female service members/Veterans (n = 656) completed an online survey assessing history (present, absent) and type (harassment-only, assault) of MST, PTSD, depression, sexual satisfaction and function symptoms, as well as suicidal ideation. Findings revealed that those who reported a history of MST, and assault more specifically, were more likely to report higher PTSD symptoms and probable PTSD diagnosis, higher depression symptoms and probable depression diagnosis, worse sexual function and probable sexual function diagnosis, lower sexual satisfaction, and presence of suicidal ideation. Those who reported harassment-only MST also reported higher PTSD severity and probable PTSD diagnosis, but the magnitude of the association of harassment-only MST and PTSD severity relative to assault MST and PTSD severity was substantially lower. Findings suggest it is critical to distinguish between history and type of MST during screening as a combined screening item loses sensitivity to identify those at heightened risk for distress and dysfunction. 相似文献

Psychology and Experimental Economics: A Gap in Abstraction 总被引:1,自引:0,他引:1
ABSTRACT— Experimental economics and social psychology share an interest in a widening subset of topics, relying on similar lab-based methods to address similar questions about human behavior, yet dialogue between the two fields remains in its infancy. We propose a framework for understanding this disconnect: The different approaches the disciplines take to translating real-world behavior into the laboratory create a "gap in abstraction," which contributes to crucial differences in philosophy about the roles of deception and incentives in experiments and limits cross-pollination. We review two areas of common interest—altruism and group-based discrimination—which demonstrate this gap yet also reveal ways in which the two approaches might be seen as complementary rather than contradictory. 相似文献

The duality of truth and falsity in a Boolean algebra of propositions is used to generate a duality of belief and disbelief. To each additive probability measure that represents belief there corresponds a dual additive measure that represents disbelief. The dual measure has its own peculiar calculus, in which, for example, measures are added when propositions are combined under conjunction. A Venn diagram of the measure has the contradiction as its total space. While additive measures are not self‐dual, the epistemic state of complete ignorance is represented by the unique, monotonic, non‐additive measure that is self‐dual in its contingent propositions. Convex sets of additive measures fail to represent complete ignorance since they are not self‐dual. 相似文献

Several studies converge on the idea that executive processes age earlier than other cognitive processes. As part of a larger effort to investigate age-related changes in executive processes in the dog, inhibitory control was measured in young, middle-aged, old, and senior dogs using size discrimination learning and reversal procedures. Compared to young and middle-aged dogs, old and senior dogs were impaired on both the initial learning of the size task and the reversal of original reward contingencies. Impaired performance in the two aged groups was characterized as a delay in learning the correct stimulus-reward contingencies and, among the senior dogs in particular, an increase in perseverative responding. These separate patterns of reversal impairments in the old and senior dogs may reflect different rates of aging in subregions of the frontal cortex. 相似文献
