The status of mood-congruent free recall bias in anxious individuals was evaluated following incidental encoding of target words. Individuals with high and low levels of trait anxiety completed a modified Stroop task, which revealed an attentional bias for threat-related stimuli in anxious individuals. This group was significantly slower in naming the colour in which threat-related words were displayed compared to neutral words. In a subsequent free recall test for the words used in the modified Stroop task, anxious individuals recalled more threat-related words compared to low-anxious people. This difference was significant even when controlling for the false recall of items that had not been presented during study. These results support the view put forward by Russo, Fox, Bellinger, and Nguyen-Van-Tam (2001) that mood-congruent free recall bias in anxious individuals can be observed if the target material is encoded at a relatively shallow level. Moreover, contrary to Dowens and Calvo (2003), the current results show that the memory advantage for threat-related information in anxious individuals is not a consequence of response bias. 相似文献

The mere presence of a potential threat of attack was found to be sufficient to lead a significant proportion of participants to engage in preemptive attacks toward potential threats; this response occurred even without an incentive for either party to attack the other. We developed a new experimental game—the preemptive strike game (PSG)—to demonstrate this tendency for defensive aggression. We also found that the rate at which participants attacked an individual representing a potential threat was not influenced by their minimal group membership; participants were no less likely to preemptively attack a member of their own minimal group and no more likely to use aggression against members of another minimal group. These findings indicate a need to further examine the role that fear-based defensive aggression, rather than anger-based spiteful aggression, plays in inter-individual and inter-group conflict. 相似文献

Research in social psychology has provided impressive evidence that intergroup contact reduces prejudice. However, to the extent that strategies based on direct contact are sometimes difficult to implement, scholars have more recently focused on indirect contact. An effective form of indirect contact is extended contact. According to the extended contact hypothesis, simply knowing that ingroup members have outgroup friends (extended contact), or observing these friendships vicariously (vicarious contact), can improve intergroup relations. Since its initial formulation a large body of studies has supported the validity of the extended contact hypothesis. In reviewing the available literature on two forms of indirect contact (extended and vicarious), we outline a model that identifies their antecedents and consequences, spanning from cognitive to affective to behavioural outcomes. In addition to identifying the main moderators of indirect contact, we also distinguish two different routes, one cognitive and one affective, that underlie what processes mediate their effects. Finally, we indicate some possible avenues for future research and we consider how direct and indirect contact strategies can be used in combination to improve intergroup relations. 相似文献

In this paper, intergroup contact was evaluated as a strategy to favor outgroup humanization. We tested a double‐mediation model, in which contact is associated with both decreased salience of intergroup boundaries and the adoption of a common identity. These recategorizations, in turn, are related to lower levels of anxiety and higher levels of empathy, both emotions being proximal predictors of outgroup humanization. The model was tested using structural equation modeling in the context of different intergroup relations: Italians versus immigrants (Study 1); Northern Italians versus Southern Italians (Study 2). Supporting the hypotheses, group representations and emotions mediated the relationship between contact and humanity attributions. The practical implications of results are discussed. 相似文献

Image theory was tested in the context of Italian/American relationships. Participants were Italian students. In addition to the images of ally, barbarian, imperialist, enemy, a new image was suggested: that of father. We predicted that political orientation would affect the structural perceptions (goal compatibility, relative power, relative status), and, as a consequence, the image of Americans: right-wing participants should prefer the images of father and ally, while left-wing participants should associate Americans with barbarian. Findings generally supported our predictions; also the figure of father obtained some support. The theoretical and practical implications of results are discussed. 相似文献

Two experiments were conducted to investigate the possibility of faster forgetting by PDAPP mice (a well-established model of Alzheimer's disease as reported by Games and colleagues in an earlier paper). Experiment 1, using mice aged 13-16 mo, confirmed the presence of a deficit in a spatial reference memory task in the water maze by hemizygous PDAPP mice relative to littermate controls. However, after overtraining to a criterion of equivalent navigational performance, a series of memory retention tests revealed faster forgetting in the PDAPP group. Very limited retraining was sufficient to reinstate good memory in both groups, indicating that their faster forgetting may be due to retrieval failure rather than trace decay. In Experiment 2, 6-mo-old PDAPP and controls were required to learn each of a series of spatial locations to criterion with their memory assessed 10 min after learning each location. No memory deficit was apparent in the PDAPP mice initially, but a deficit built up through the series of locations suggestive of increased sensitivity to interference. Faster forgetting and increased interference may each reflect a difficulty in accessing memory traces. This interpretation of one aspect of the cognitive deficit in human mutant APP mice has parallels to deficits observed in patients with Alzheimer's disease, further supporting the validity of transgenic models of the disease. 相似文献

The current study examines the role of contact on reactions to gay and heterosexual targets by U.S. heterosexual college students.
Aversive bias research finds that minority group members receive unfavorable evaluations only when non-category-based information
justifies bias. We argue that under other conditions, namely absence of conditions justifying bias, minority group members
receive more favorable evaluations than non-minorities, an effect we term overcorrection. We apply this research to the study
of attitudes toward gay men. The current study examines this effect on evaluations of a highly qualified male job candidate
who is either gay or heterosexual and flawed or not flawed. We predicted and found, among 180 college students, that the overcorrection
effect was present only for those individuals who have experienced no friendships with gay men. Those individuals who do have
gay male friends did not exhibit overcorrection. We interpret this result as an indication that individuals who have gay friends
(contact) ignore category information such as gay/ heterosexual and are more likely to exhibit truly egalitarian ratings.
Implications for aversive bias and outgroup covariation perspectives are discussed.

The aim of this experiment is to examine whether communicating the results of social psychological research improves out‐group stereotypes and diminishes in‐group bias. The experimental material consisted of 2 communications: one described Hamilton and Gifford's (1976) experiment on illusory correlation (Experiment 1); the other described Sherif's (1966) studies on summer camps. The results of the present experiment show that knowledge of Sherif's findings had no effect on evaluations, whereas an awareness of the experiment on illusory correlation produced a boomerang effect, accentuating, rather than diminishing, in‐group bias. A second experiment revealed that the persuasive power of a scientific message on stereotypes depends on whether in‐groups and out‐groups are cogni‐tively present in the message acquisition phase. 相似文献
