Accuracy in discrimination of self-reported cooperators using static facial information

People readily ascribe personality traits to others and believe that faces hold important guides to character. Here we examined the relationship between static facial appearance and self-reported cooperation/defection using the prisoner’s dilemma (N = 193). Study 1 combined face images of those self-reporting they would be most and least likely to cooperate. The composites of cooperators were seen as more cooperative than non-cooperators. Study 2 demonstrated accuracy with ratings of individual faces. Masculinity of face shape was negatively related to self-reported cooperation for men, but not women. Further, ratings of smile intensity were positively, but not significantly, related to self-reported cooperation. Overall, individuals appear able judge the potential of others to cooperate from static facial appearance alone at rates greater than chance.     

Correlated male preferences for femininity in female faces and voices

Sexually dimorphic physical traits are important for mate choice and mate preference in many species, including humans. Several previous studies have observed that women's preferences for physical cues of male masculinity in different domains (e.g., visual and vocal) are correlated. These correlations demonstrate systematic, rather than arbitrary, variation in women's preferences for masculine men and are consistent with the proposal that sexually dimorphic cues in different domains reflect a common underlying aspect of male quality. Here we present evidence for a similar correlation between men's preferences for different cues of femininity in women; although men generally preferred feminized to masculinized versions of both women's faces and voices, the strength of men's preferences for feminized versions of female faces was positively and significantly correlated with the strength of their preferences for feminized versions of women's voices. In a second study, this correlation occurred when men judged women's attractiveness as long-term, but not short-term, mates, which is consistent with previous research. Collectively, these findings (1) present novel evidence for systematic variation in men's preferences for feminine women, (2) present converging evidence for concordant preferences for sexually dimorphic traits in different domains, and (3) complement findings of correlations between women's facial and vocal femininity.     

Sexual dimorphism of male face shape,partnership status and the temporal context of relationship sought modulate women's preferences for direct gaze

Most previous studies of face preferences have investigated the physical cues that influence face preferences. Far fewer studies have investigated the effects of cues to the direction of others' social interest (i.e. gaze direction) on face preferences. Here we found that unpartnered women demonstrated stronger preferences for direct gaze (indicating social interest) from feminine male faces than from masculine male faces when judging men's attractiveness for long‐term relationships, but not when judging men's attractiveness for short‐term relationships. Moreover, unpartnered women's preferences for direct gaze from feminine men were stronger for long‐term than short‐term relationships, but there was no comparable effect for judgements of masculine men. No such effects were evident among women with romantic partners, potentially reflecting different motivations underlying partnered and unpartnered women's judgements of men's attractiveness. Collectively these findings (1) complement previous findings whereby women demonstrated stronger preferences for feminine men as long‐term than short‐term partners, (2) demonstrate context‐sensitivity in the integration of physical and social cues in face preferences, and (3) suggest that gaze preferences may function, at least in part, to facilitate efficient allocation of mating effort.     

Integrating gaze direction and expression in preferences for attractive faces

Few studies have investigated how physical and social facial cues are integrated in the formation of face preferences. Here we show that expression differentially qualifies the strength of attractiveness preferences for faces with direct and averted gaze. For judgments of faces with direct gaze, attractiveness preferences were stronger for smiling faces than for faces with neutral expressions. By contrast, for judgments of faces with averted gaze, attractiveness preferences were stronger for faces with neutral expressions than for smiling faces. Because expressions can differ in meaning depending on whether they are directed toward or away from oneself, it is only by integrating gaze direction, facial expression, and physical attractiveness that one can unambiguously identify the most attractive individuals who are likely to reciprocate one's own social interest.     

Cognitions,Attitudes and Decision-Making in Search and Seizure Cases 1

This study investigated decision-making in a search and seizure context. Specifically, the study examined the viability of a tort remedy for deterring police from illegal searches. The decision is made in a context common in legal settings: the decision-maker is supposed to ignore available information (in this case, knowledge about the outcome of the search). This type of judgment allows for the operation of many cognitive influences, such as a hindsight bias-like process and the influence of attitudes and cognitive schemas. A search scenario was presented to 377 subjects; each scenario had one of three different endings—drugs were found (guilty), no evidence was found (not guilty), or no mention was made of the outcome (neutral). The results showed that knowledge of the outcome of the search influenced damage judgements, such that a guilty outcome led to lower damage awards. Outcome knowledge also influenced reconstruction of the events in the scenario, such that a guilty outcome led to a distortion of information in the direction of incriminating the defendant. The results also showed that well-organized and coherent ideological belief systems exert an independent influence on both awards and reconstruction of events.     

Effects of anger management and goal setting group interventions on state-trait anger and self-efficacy beliefs among high risk adolescents

In this study we evaluated the effects of two psychoeducational groups (anger management and goal setting) on state and trait anger, anger expression, and on self-efficacy beliefs of high risk adolescents enrolled in an alternative high school. Participants (n = 57) were pre- and post-tested using the State Trait Anger Expression Inventory (STAXI) with subscales for (a) state anger, (b) trait anger, and (c) anger expression, and on a measure of self-efficacy related to (a) anger management, (b) goal setting, and (c) group behavior and interpersonal communication. We hypothesized that each treatment would favorably impact the self-efficacy items related to it, that participants in both treatment groups would show gains in self-efficacy for general group behavior and communication skills, and that the anger management treatment would decrease state anger and anger expression. Results of a series of Repeated Measures ANOVAS revealed no group effects or group by time interaction effects. Analysis of Cohen's d effect sizes for the treatment groups in comparison with the control condition indicated only small treatment effects for the goal setting group on the STAXI, and small, negative treatment effects for the anger management group on the STAXI and on state anger. Thus, results failed to support the hypotheses with the current data set. Limitations of this study and implications for future research and group practice within schools are discussed. The authors thank Ellen Hawley McWhirter, Greg Sandstrom, and the administration, faculty, and students of the participating “alternative high school” for their help and support.     

Response-shock delay as a reinforcer in avoidance behavior

After rats received preliminary training to avoid shock on a discrete-trial retractable-bar avoidance procedure, the procedure was changed such that responses retracted the lever but did not affect the rate of shock. Responses only delayed the onset of shock. About half of the animals under these procedures responded consistently on almost 100% of the discrete-trial cycles over days. When short latencies maximized the response-shock delay, animals tended to make short-latency responses. When long latencies maximized the response-shock delay, animals tended to make long-latency responses. When all response latencies produced the same response-shock delay, animals made differing average-latency responses. And, when responses did not delay shock, most of the animals primarily engaged in shock-elicited responding while the other animals engaged in preshock responding.     

A COMPARISON OF TECHNIQUES WHICH TEST FOR JOB DIFFERENCES

There has been a recent trend in research seeking the most appropriate statistical technique for determining job similarities/differences. Monte Carlo methods were used to analyze more closely the repeated measures analysis of variance and the multivariate analysis of variance in order to add further insight into the viability of these techniques for this purpose. The conventional univariate analysis of variance, the ε-adjusted univariate F test, and the ε-adjusted univariate F test were compared to three multivariate tests (Roy's largest-root criterion, Wilk's likelihood ratio, and the Pillai-Barlett trace) in terms of power and control for Type I error when (1) circularity and homogeneity were met, (2) homogeneity was met but circularity was violated, (3) homogeneity was violated but circularity was met, and (4) both homogeneity and circularity were violated. The efficacy of the techniques was shown to be contingent upon whether the assumptions were met or not. The univariate test proved to be the better technique when circularity was met. The multivariate technique proved to be the better test when homogeneity was met while circularity was violated. The results were mixed when both circularity and homogeneity were violated. Guidelines for selecting a statistical technique which tests for job differences are offered.
