Evidence from Meta-Analyses of the Facial Width-to-Height Ratio as an Evolved Cue of Threat
The facial width-to-height ratio (FWHR) is the width of the face divided by the height of the upper face. There is mixed evidence for the hypothesis that the FWHR is a cue of threat and dominance in the human face. We conducted a systematic review and meta-analyses of all peer-reviewed studies (and 2 unpublished studies) to estimate the magnitude of the sex difference in the FWHR, and the magni...
متن کاملWithin-person variability in men’s facial width-to-height ratio
Background. In recent years, researchers have investigated the relationship between facial width-to-height ratio (FWHR) and a variety of threat and dominance behaviours. The majority of methods involved measuring FWHR from 2D photographs of faces. However, individuals can vary dramatically in their appearance across images, which poses an obvious problem for reliable FWHR measurement. Methods. ...
متن کاملGroup Facial Width-to-Height Ratio Predicts Intergroup Negotiation Outcomes
Past studies have found that the facial width-to-height ratio (FWHR) is associated with a range of traits and behaviors that are possibly important to dyadic negotiations. However, it is unknown whether the FWHR would have an impact on intergroup negotiations, which happen frequently and often have higher stakes in the real world. To examine this question, in the current study, we randomly assi...
متن کاملCue reactivity in smokers: an event-related potential study.
Drugs-of-abuse may increase the salience of drug cues by sensitizing the dopaminergic (DA) system (Robinson and Berridge, 1993), leading to differential attention to smoking stimuli. Event-related potentials (ERPs) have been used to assess attention to smoking cues but not using an ERP component associated with DA-mediated salience evaluation. In this study the DA-related P2a and the P3, were c...
متن کاملSelf-Fulfilling Prophecies as a Link between Men’s Facial Width-to-Height Ratio and Behavior
The facial width-to-height ratio (fWHR) has been identified as a reliable predictor of men's behavior, with researchers focusing on evolutionary selection pressures as the underlying mechanism explaining these relationships. In this paper, we complement this approach and examine the extent to which social processes also determine the extent to which men's fWHR serves as a behavioral cue. Specif...
