Gaze avoidance: Personality and social judgments of people who avoid direct face-to-face contact

Some people maintain direct, face-to-face contact during interaction, whereas others avert their gaze or turn their face while interacting. Research on individual differences in gaze avoidance, while sparse, falls into two areas. One concerns the personality and psychopathology correlates of gaze aversion, and the other concerns social judgments made of people who avert their gaze during interaction. The findings generally show that gaze aversion is associated with unfavorable traits (shyness, social anxiety, risk for schizophrenia) and negative social evaluations (gaze averse people are rated as more deceptive and less sincere). The present study took advantage of an archival data set that contained facial photographs from which gaze avoidance could be scored. The correlates of gaze avoidance were different for men and women. Gaze avoidant men tended to be emotionally inhibited and overcontrolled, and reported a high incidence of various psychosomatic and physical symptoms. Gaze avoidant women, on the other hand, were high on measures of psychopathy, hysteria, and traditional femininity, they tended to have fewer physical symptoms. Gaze avoidant women were also viewed by others in a negative light (as being disagreeable, unconscientious, unattractive, and even somewhat lower on intelligence). In males, none of the social judgment variables correlated significantly with gaze avoidance. Results are discussed in terms of sex differences in the meaning and communicative function of this non-verbal social behavior.     

Nifty ways to leave your lover: The tactics people use to entice and disguise the process of human mate poaching

Although a number of studies have explored the ways that men and women romantically attract mates, almost no research exists on the special tactics people use when already in a relationship and trying to attract someone new--a process known as mate poaching enticement. In Study 1, the authors investigated the tactics people use to entice others into making mate poaching attempts. Enticement tactic effectiveness conformed to evolutionary-predicted patterns across sex and temporal context. In Study 2, the authors examined the tactics men and women use to disguise mate poaching enticement. The most effective camouflage for poaching also varied between sex in evolutionary-predicted ways, regardless of the target of deception (i.e., current partner vs. larger community). Discussion focuses on limitations of this research, future investigative directions, unexpected findings, and the utility of placing mate poaching attraction within the broader context of human sexual strategies.     

Adaptations to avoid victimization

From an evolutionary perspective, victims are individuals who incur fitness costs as the result of the actions of external agents. The external agents that inflict the costs are often other humans. In the evolutionary past, there were recurrent contexts of conflict in the fitness interests of different individuals. Evidence suggests that many instances of the infliction of costs on conspecifics are the evolved products of adaptations that function to acquire and control fitness-enhancing resources and goals. We propose that an antagonistic, coevolutionary arms race that has churned through the deep time of human evolutionary history has produced adaptations to strategically exploit others and defenses to avoid the costs of victimization.     

Experimental activation of anti-cuckoldry mechanisms responsive to female sexual infidelity

Recent research indicates that men may have evolved mechanisms dedicated to detecting and responding to the risk of partner infidelity. Because activation of these “anti-cuckoldry” mechanisms depends on partner infidelity, or the perception of partner infidelity, existing evidence for such mechanisms relies on correlational data. The current study tests several predictions regarding men’s anti-cuckoldry mechanisms in an experimental design. As predicted, the results demonstrated: (1a) experimental activation of men’s anti-cuckoldry mechanisms by presenting them with a vignette depicting a female partner’s sexual infidelity; (1b) no activation of men’s anti-cuckoldry mechanisms by presenting them with a vignette depicting a sexual encounter without female infidelity; (2) experimental activation of men’s anti-cuckoldry mechanisms was influenced by their perceived risk of partner infidelity; and (3) women were not influenced by the partner infidelity manipulation.     

An exploratory analysis of the contexts and circumstances of filicide‐suicide in Chicago, 1965–1994

Filicide is the killing of a ward by a parent. Relative to many other types of homicide, filicide is an infrequent event. Filicide followed by the offender's suicide is less frequent still. The contexts and circumstances surrounding filicide‐suicide may nevertheless provide insight into parental psychology. Some research suggests, for example, that filicidal genetic parents are more likely to commit suicide than are filicidal stepparents. Five hypotheses are tested for this study, using a database that includes incident‐level information on over 22,000 homicides committed in Chicago during the years 1965–1994. Findings do not support the hypothesis of differential risk of suicide following filicide by genetic parents and stepparents. Previous work is replicated, indicating that: (1) filicides that include multiple victims are more likely to end in the offender's suicide than are filicides that include a single victim, (2) parents are more likely to commit suicide following a filicide of an older child than a filicide of a younger child, (3) older parents, relative to younger parents, are more likely to commit suicide following filicide, and that (4) fathers, relative to mothers, are more likely to commit suicide following filicide. Discussion suggests future directions for research that can inform our understanding of filicide and of filicide‐suicide. Aggr. Behav. 00:000–000, 2005. © 2005 Wiley‐Liss, Inc.     

Human sexual conflict from molecules to culture

Coevolutionary arms races between males and females have equipped both sexes with mutually manipulative and defensive adaptations. These adaptations function to benefit individual reproductive interests at the cost of the reproductive interests of opposite- sex mates, and arise from evolutionary dynamics such as parental investment (unequal reproductive costs between the sexes) and sexual selection (unequal access to opposite-sex mates). Individuals use these adaptations to hijack others' reproductive systems, psychological states, and behaviors-essentially using other individuals as extended phenotypes of themselves. Such extended phenotypic manipulation of sexual rivals and opposite-sex mates is enacted by humans with the aid of hormones, pheromones, neurotransmitters, emotions, language, mind-altering substances, social institutions, technologies, and ideologies. Furthermore, sexual conflict may be experienced at an individual level when maternal genes and paternal genes are in conflict within an organism. Sexual conflict may be physically and emotionally destructive, but may also be exciting and constructive for relationships. By extending the biological concept of sexual conflict into social and cultural domains, scholars may successfully bridge many of the interdisciplinary gaps that separate the sciences from the humanities.     

Understanding suicide terrorism: Premature dismissal of the religious-belief hypothesis

We comment on work by Ginges, Hansen, and Norenzayan (2009), in which they compare two hypotheses for predicting individual support for suicide terrorism: the religious-belief hypothesis and the coalitional-commitment hypothesis. Although we appreciate the evidence provided in support of the coalitional-commitment hypothesis, we argue that their method of testing the religious-belief hypothesis is conceptually flawed, thus calling into question their conclusion that the religious-belief hypothesis has been disconfirmed. In addition to critiquing the methodology implemented by Ginges et al., we provide suggestions on how the religious-belief hypothesis may be properly tested. It is possible that the premature and unwarranted conclusions reached by Ginges et al. may deter researchers from examining the effect of specific religious beliefs on support for terrorism, and we hope that our comments can mitigate this possibility.     

Sex ratio and mate preferences: a cross‐cultural investigation

Sex ratio is the number of men per 100 reproductive‐age women within a specified mating pool. We generated and tested two hypotheses about the cross‐cultural relationships between sex ratio and mate preferences using preference ratings of 18 characteristics provided by 9809 participants and corresponding sex ratio data secured from an international organization. The Classical Sex Ratio Mate Preference Shifts Hypothesis predicts that in imbalanced sex ratio societies, the more numerous sex will lower their standards, to facilitate acquisition of a partner of the less numerous sex. The Alternative Sex Ratio Mate Preference Shifts Hypothesis predicts that in lower sex ratio societies, men will lower their standards to secure more short‐term matings, whereas women will raise their standards to avoid deception by men seeking short‐term relationships. Results supported the Classical Sex Ratio Mate Preference Shifts Hypothesis for men, and the Alternative Sex Ratio Mate Preference Shifts Hypothesis for women. Discussion addresses limitations of the current research and highlights future directions for research on the relationships between sex ratio and mating psychology and behavior.
