In research on selective exposure to information, people have been found to predominantly seek information supporting rather than conflicting with their opinion. In most of these studies, participants were allowed to search for as many pieces of information as they liked. However, in many situations, the amount of information that people can search for is restricted. We report four experiments addressing this issue. Experiment 1 suggests that objective limits regarding the maximum number of pieces of information the participants could search for increases the preference for selecting supporting over conflicting information. In Experiment 2, just giving participants a cue about information scarcity induces the same effect, even in the absence of any objective restrictions. Finally, Experiment 3 and 4 clarify the underlying psychological process by showing that information limits increase selective exposure to information because information search is guided by the expected information quality, which is basically biased towards supporting information, and information limits act to reinforce this tendency.

Verplanken, Hofstee, and Janssen (1998) found that the affective component of attitude is accessed more readily than the cognitive. Three studies further examined these findings in the light of two competing explanations: affective primacy, which states that emotional material is inherently more accessible than cognitive; and evaluative primacy, which states that emotional material is more accessible only if it is inherently more evaluative or supports the overall evaluative basis of attitude. Study 1 measured the accessibility of cognitive and affective traits while equalizing the evaluative nature of these traits. This study found a speed advantage for affective traits, but the attitude objects in this study turned out to be mainly affectively based. Studies 2 and 3, using a mixture of affectively and cognitively based objects, found that the speed advantage for affective terms was only found among affectively based objects; Study 3 also found a speed advantage for cognitive terms among cognitively based objects, and additionally found that individual differences in attitude basis explained part of this interaction. Collectively, these studies show that while affective material may be accessed more quickly than cognitive, this is most true when overall evaluation is based on affect rather than cognition.

Within the framework of an intergroup relations paradigm, three studies analysed the role of in‐group threat in intergroup discrimination and the influence of in‐group norms on intergroup discrimination. The first study showed that perceived socio‐economic threat underlies Swiss nationals' prejudice and discrimination toward foreigners in Switzerland. The second and third studies experimentally tested the hypotheses, first, that variations in perception of in‐group threat will produce change in initial discrimination, and, second, that the influence of an in‐group norm (pro‐ vs. anti‐ discriminatory) is moderated by the perception of in‐group threat. In support of these predictions, results of both studies indicated that discrimination was reduced when perceived in‐group threat was low. However, the anti‐discriminatory in‐group norm reduced discrimination only when perceived in‐group threat was low. No influence was observed for the pro‐discriminatory in‐group norm.

GABA‐A receptor is a transmembrane hetero‐oligomeric protein which consists of five subunits, the combination of which confers unique pharmacological properties to the receptor. It is well‐known that the GABAergic system is involved in the modulation of aggression. However, the role of α5/GABA‐A receptors has not been explored. In this study, we examined the effect of L‐655,708 (0.625‐5 mg/kg), a selective ligand for the benzodiazepine site of GABA‐A receptors which contain the α5 subunit, on agonistic behavior elicited by isolation in male mice. Individually housed mice were exposed to an anosmic “standard opponent” 30 min after drug administration, and the encounters were videotaped and evaluated using an ethologically based analysis. L‐655,708 (5 mg/kg) exhibited an ethopharmacological profile characterized by a marked reduction of the time spent in offensive behavior (threat and attack) without affecting immobility, accompanied by a significant increase of avoidance/flee and nonsocial exploration behaviors, suggesting that the antiaggressive effect of the drug is unselective. Overall, this behavioral profile might indicate the existence of an anxiogenic‐like activity of L‐655,708 in mice. Aggr. Behav. 30:319–325, 2004. © 2004 Wiley‐Liss, Inc. 相似文献

Because of burgeoning participation by children in forensic situations there is significant concern about children's memory for stressful events. Influence of timing of the first interview and interview frequency on long‐term recall were evaluated by comparing three groups of 3‐ to 9‐year‐olds 1 year after an injury requiring emergency room treatment. One group had one interview, a year after injury; another group had two interviews, immediately and a year later; the third group had three interviews, immediately, 6 months and a year after injury. The type of event and timing of the initial interview influenced completeness and accuracy of recall after 1 year. All children showed extensive recall but having an immediate interview was associated with greater completeness and accuracy for 3–4‐year‐olds but not older children. This suggests a social influence: a highly structured and organized early interview may have beneficial effects on memory for preschoolers. Implications for questioning and testimony are discussed.

In this essay I question an assumption of Card's, which seems to place the (Kantian'style) ethical in a directive relationship with respect to the political. I call attention to the rupture between the two as a marker of modernity and suggest that the political is not only a sphere of power but also a value‐sedimented field, with the values in question developing historically as in the case of liberal democracy. 相似文献

Research on willingness to make marginal investments (e.g., the escalation and sunk cost literatures) has often focused on project completion decisions, such as the “radar‐blank plane.” This paper discusses a fundamentally different type of marginal investment decision, that of couples deciding whether to continue infertility treatment in the face of repeated failures. Two experiments based on this context show that when people face multiple independent chances to achieve a valued goal but are unsure about chances of success, premature quitting or “de‐escalation” is the norm. Repeated negative feedback appears to induce individuals to see each successive failure as more and more diagnostic. As a result, even a short series of failed attempts evokes beliefs that future attempts will also fail. These emergent expectations of failure, generated by causal attribution processes, associative learning, and/or discounting of ambiguous information, appear very compelling and induce people to forgo profitable marginal investments.

Preference reversal is a systematic change in the preference order between options when different response methods are used (e.g., choice vs. judgment). The present study focuses on procedures used to elicit preferences according to an evaluability hypothesis. Two experiments compared joint vs. separate evaluations and explicit vs. non‐explicit joint evaluations. Subjects had to express preferences between high‐variance gambles (HVGs) and low‐variance gambles (LVGs) either by choosing one gamble to play in a lottery or by assigning gambles minimum selling prices. We show that HVGs are preferred in both choice and pricing conditions when gambles are evaluated separately, and LVGs are preferred in both choice and selling conditions when gambles are evaluated in pairs: i.e., when the evaluation mode is held constant, classic preference reversal disappears. These results support the evaluability hypothesis, and suggest that preferences depend on whether subjects are allowed to compare the options they are asked to choose from or judge, independently of the nature of the scale (i.e., attractiveness vs. minimum selling price) they are required to adopt.
