疾病的心理防御：人类如何应对病菌威胁

病菌和传染病构成的选择压力导致动物进化出了身体免疫以及行为免疫反应。而人类的大脑进化促使他们发展出了最为复杂的行为免疫系统。很早开始, 我们就依赖自身的各种行为免疫反应抵抗病菌。当这些疾病抵御机制跟群体生活协同进化之后, 我们的很多社会行为和态度都具有了减少疾病感染的功能, 它们包括对外群体成员的偏见、歧视, 以及对内群体成员的从众、服从。而更高层次的文化差异比如集体主义-个人主义, 至少部分原因是要管理与疾病感染有关的风险。本篇综述讨论了与抵御病菌威胁有关的社会行为、态度和其他心理现象。     

Stereotype Threat in Men on a Test of Social Sensitivity

This study provides evidence of stereotype threat in men on a test of a feminine ability called social sensitivity, that is, the ability to decode nonverbal cues. Men who were told that the test assessed social sensitivity and produced better scores for women than men performed worse on the test than did men who were told that the test assessed information processing. Because social sensitivity can be an automatic skill and stereotype threat uses mental capacity, this effect was moderated by self-reported strategy usage. Mens performance worsened in the threat condition only when they reported more deliberative and less intuitive strategies for decoding nonverbal cues.     

Physiological arousal and reactions to outgroup members during competitions that implicate an important social identity

Exposure to sports competitions, especially those involving violence, can elevate physiological arousal, potentially setting the stage for transforming hostile inclinations into aggressive behavior. Personality and cognitive factors that influence the interpretation given to such competitions may influence the impact of these events. The effects of exposure to a sporting competition that had high or low importance for subjects' social identity on pre- to post-film blood pressure and evaluations of outgroups were examined. Aggression may be particularly likely when arousal levels are elevated, and such arousal was expected to be determined by the importance of the identity at stake, regardless of the outcome of the competition. Individuals who were either strongly identified with America or were less identified viewed a boxing match where the American athlete lost the competition (and the Russian contestant won), or the Russian athlete lost (and the American won). Both diastolic and systolic blood pressure measures showed an increase pre- to post-film in the highly identified persons while no such change was observed in the low identitied individuals. Cognitive measures assessing evaluations of the Russian boxer, and Russians in general, showed effects parallel to the arousal indexes with high identified persons expressing more derogation of threat-relevant targets than did those low in identification. Arousal increases in only the highly identified viewers predicted derogation of Russians. Discussion centers on the role of identification with a sports team on physiological processes and their implications for spectator aggression.     

The Interplay among Stereotypes, Performance-Avoidance Goals, and Women's Math Performance Expectations

This project was designed to examine whether and how achievement goals contribute to the effect of gender stereotypes on women's low expectancies for success on math tasks. Study 1 confirmed predictions from the Stereotyped Task Engagement Process (STEP) model (Smith, 2004) by demonstrating that, compared to a counter-stereotype situation, women reminded of the gender-stereotype endorsed performance-avoidance goals. Study 2 tested whether performance-goal adoption differed between men and women. Results showed that, compared to men, women in a stereotype salient math situation were more likely to endorse performance-avoidance achievement goals. This performance-avoidance goal adoption in turn, accounted for the negative relationship between participants' gender and performance expectations for a standardized math test.     

Stereotype Lift

When a negative stereotype impugns the ability or worth of an outgroup, people may experience stereotype lift—a performance boost that occurs when downward comparisons are made with a denigrated outgroup. In a meta-analytic review, members of non-stereotyped groups were found to perform better when a negative stereotype about an outgroup was linked to an intellectual test than when it was not (d=.24,p<.0001). Notably, people appear to link negative stereotypes to evaluative tests more or less automatically. Simply presenting a test as diagnostic of ability was thus sufficient to induce stereotype lift. Only when negative stereotypes were explicitly invalidated or rendered irrelevant to the test did the lift effect disappear.     

Threat Vigilance in Child Witnesses of Domestic Violence: A Pilot Study Utilizing the Ambiguous Situations Paradigm

Research has found that children exposed to family violence exhibit higher rates of maladjustment. We review relevant literature on family violence, marital conflict, and cognitive factors implicated in child behaviour problems. A bias toward perceiving threat in ambiguous contexts has been identified as one factor mediating both aggressive and anxious behaviour disorders. We conducted a study utilizing the ambiguous situations paradigm to assess whether children exposed to violent spousal conflict were more likely than children not exposed to violence (divided into children with an externalizing behaviour disorder and non-clinic children) to perceive threat in two classes of ambiguous situations: Peer and Inter-Parental. The results indicated that children exposed to violent spousal conflict perceived more threat in parental situations than either of the other two groups. A number of considerations were taken into account given the exploratory nature of the study, particularly sample limitations. We conclude with suggestions for improvements to the research design and the further relevance of exploring cognitive factors involved in the adjustment of children from backgrounds of violence.     

May the force be with you

This paper is a critical assessment of argumentum ad baculum, or appeal to force. Its principal contention is that, contrary to common opinion, there is no general fallacy of ad baculum. Most real-life ad baculums are, in fact, fairly strong. A basic logical form for reconstructed ad baculums is proposed, and a number of heterodoxical conclusions are also advanced and argued for. They include that ad baculum is not necessarily a prudential argument, that ad baculum need not involve force, violence, or threats, and that one can argue ad baculum to oneself. The starting point of the paper, however, is a critical evaluation of three ad baculums from the exercise sets of Irving Copi's well-known Introduction to Logic.     

Evidence that blatant versus subtle stereotype threat cues impact performance through dual processes

An experiment tested three competing hypotheses for how blatant and subtle stereotype threat cues influence the performance of female sports participants on a golf-putting task. A “predominant” model predicts that blatant threat cues have a more negative effect on performance than subtle threat cues, whereas an “additive” model predicts that both cues combine to have a greater negative effect than either threat cue alone. However, a “dual process” model predicts that each threat cue has an independent negative influence through separate mechanisms. To test these predictions, we varied the presence of blatant (e.g., the task frame) and subtle cues (e.g., the gender of the experimenter) for negative stereotypes about female athletes, and then measured both the number of strokes required to finish the course and accuracy on the last putt of each hole. The results supported the dual process model prediction: females required more strokes to finish the golf task when it was framed as measuring gender differences compared to racial differences in athletic ability, and females performed less accurately on the last putt of each hole in the presence of a male versus a female experimenter. The discussion focuses on how the presence of multiple stereotype threat cues can induce independent mechanisms that may have separate but simultaneously deleterious effects on performance.     

The many faces of stereotype threat: Group- and self-threat

Contending with negative intellectual stereotypes has been shown to depress the academic performance of targets of the stereotypes [Steele, C. M. (1997). A threat in the air: How stereotypes shape intellectual identity and performance. American Psychologist, 52, 613-629]. The present paper examines whether women’s mathematics performance is differentially affected by the concern of confirming that a negative stereotype is true of the self (self-threat), than by the concern of confirming that the stereotype is true of their gender (group-threat). In two studies we independently manipulated these different threats for women taking a mathematics test. Gender identification moderated the effect of group-threats on test performance; only women highly identified with their gender underperformed. The performance of less gender-identified women was unaffected by group-threats. In contrast, gender identification did not moderate the effect of self-threats—both high- and low-identified women underperformed. The results of these studies suggest that women’s math performance is differentially affected by the source of the threat.     

From infra-humanization to discrimination: The mediation of symbolic threat needs egalitarian norms

This set of studies tests the link between infra-humanization, symbolic threat, and discrimination within normative contexts. In two experiments, manipulating the degree of humanity of a disliked outgroup has an effect upon the discrimination towards it. The infra-humanized outgroup is more discriminated than the humanized one. Also, the perception of symbolic threat plays the role of a justifying factor for discrimination, and mediates the relationship between degrees of humanity and discrimination. Study 2 further shows that this mediation occurs only when an egalitarian norm is activated, and not when meritocracy is made salient. The discussion focuses on factors likely to prevent infra-humanization of outgroups. It also considers how norms may change the role of threat.
