Does Men’s Facial Sexual Dimorphism Affect Male Observers’ Selective Attention?
Facial sexual dimorphism affects observers’ physical dominance ratings. Here, we test whether such perceived dominance influences selective attention. To minimize demand characteristics, we examined whether task-irrelevant masculinized men’s faces would show an attentional bias in several experimental paradigms. Experiment 1 employed a Posner Cueing Paradigm in which participants classified shapes after a masculinized or feminized man’s face was presented. We could not find a difference in participants’ classification speeds when either feminized or masculinized face cued target position. Experiment 2 employed a Flanker Task in which participants judged letter orientation, while ignoring flanking faces. There was no observed difference in participants’ reaction time (RT) when masculinized faces flanked the target. Experiment 3 employed a Dot Probe Task, where participants were presented with a masculinized face and a feminized face to the left and right of center screen, and a target shape was presented in the location of one face. Participants’ task was to classify shape orientation. We observe a small effect of facial sexual dimorphism on participants’ classification speed. In Experiment 4, we primed participants with images meant to induce fear or arousal before each trial of a Dot Probe Task. Following the presentation of a fear inducing picture, participants RT to classify shapes when a masculinized face cued target position did not differ from when a feminized face cued target position. The two different presentation times did not create different patterns of results, indicating that masculinized faces did not induce either a cueing or inhibitory affect. Overall, we failed to support the hypothesis that people selectively attend to masculinized faces when they are presented as irrelevant information
Effects of Voice Pitch on Social Perceptions Vary With Relational Mobility and Homicide Rate
Fundamental frequency ( fo) is the most perceptually salient vocal acoustic parameter, yet little is known about how its perceptual influence varies across societies. We examined how fo affects key social perceptions and how socioecological variables modulate these effects in 2,647 adult listeners sampled from 44 locations across 22 nations. Low male fo increased men’s perceptions of formidability and prestige, especially in societies with higher homicide rates and greater relational mobility in which male intrasexual competition may be more intense and rapid identification of high-status competitors may be exigent. High female fo increased women’s perceptions of flirtatiousness where relational mobility was lower and threats to mating relationships may be greater. These results indicate that the influence of fo on social perceptions depends on socioecological variables, including those related to competition for status and mates

Women’s Strategic Defenses Against Same-Sex Aggression: Evidence From Sartorial Behavior
Observers use facial masculinity to make physical dominance assessments following 100-ms exposure.
Research has consistently demonstrated that faces manipulated to appear more masculine are perceived as more dominant. These studies, however, have used forced-choice paradigms, in which a pair of masculinized and feminized faces was presented side by side. These studies are susceptible to demand characteristics, because participants may be able to draw the conclusion that faces which appear more masculine should be rated as more dominant. To prevent this, we tested if dominance could be perceived when masculinized or feminized faces were presented individually for only 100 ms. We predicted higher dominance ratings to masculinized faces and better memory of them in a surprise recognition memory test. In the experiment, 96 men rated the physical dominance of 40 facial photographs (masculinized = 20, feminized = 20), which were randomly drawn from a larger set of faces. This was followed by a surprise recognition memory test. Half of the participants were assigned to a condition in which the contours of the facial photographs were set to an oval to control for sexual dimorphism in face shape. Overall, men assigned higher dominance ratings to masculinized faces, suggesting that they can appraise differences in facial sexual dimorphism following very brief exposure. This effect occurred regardless of whether the outline of the face was set to an oval, suggesting that masculinized internal facial features were sufficient to affect dominance ratings. However, participants' recognition memory did not differ for masculinized and feminized faces, which could be due to a floor effect
Jealousy Mediates the Link Between Women’s Upward Physical Appearance Comparison and Mate Retention Behavior
A Psychometric Evaluation of the Intrasexual Competition Scale
The Intrasexual Competition Scale (ICS) measures the extent to which individuals view their interaction with same-sex others in competitive terms. Although it is frequently used in studies investigating differences in mating behavior, the factor structure of the ICS has never been confirmed. Researchers have yet to use multiple-group confirmatory factor analysis to test whether the properties of the scale are equivalent between the sexes. In Study 1, we report on an investigation in which participants’ responses to the ICS were submitted to exploratory factor analysis (EFA). In Study 2A, we compared the fit of one and two-factor models from the EFA as well as two additional models, using confirmatory factor analysis with an independent sample. The best fit was obtained by a two-factor solution, which reflected: (1) respondents’ feelings of frustration when intrasexual competitors are better off (Inferiority Frustration), and (2) respondents’ enjoyment of being better than intrasexual competitors (Superiority Enjoyment). This model achieved a high degree of measurement invariance. In Study 2B, we found the ICS had good concurrent validity via associations with sociosexuality, mating effort, and sexual behavior. Together, these analyses suggest that the ICS is a valid measure of intrasexually competitive attitudes
