Research

Our research focuses on the study of human social interaction and cognition, especially on human mate preference and interpersonal attraction. We employ the evolutionary psychology framework, thus investigating the evolutionary causes and consequences of human behavior in social context. Our studies can be categorized, broadly, into the following topics:

Human facial and body morphology

Studies on human facial and body morphology include the investigation of human face/body shape and the role of visible skin condition on perception of others. For example, we have investigated attractiveness perception of male/female faces and bodies in relation to measures of physical strength and symmetry as well as ovulatory-cycle dependent female preferences of male features. More recently, we have been studying the effect of skin topography and skin colouration cues on perception of male and female facial age, health and attractiveness.

Human body movement and nonverbal communication

The focus of our work on human body movement is on the signalling value of human dance. By employing 2D (video) and 3D (motion-capture) technology, we have been investigating cues people derive from male and female dance movements. Current research aims to expand insight derived from the study of Western societies to other (non-Western) populations.

Digit ratio and sex-dependent traits/behavior

Digit ratio (2D:4D) is supposed to be a biomarker of prenatal exposure to sex steroids and has been shown to correlate with a variety of sex-dependent physical, cognitive and behavioral measures. We have been investigating this trait, for example, in relation to facial morphology, physical strength, and personality. Recent studies consider large samples to investigate associations of digit ratio and sex-dependent behavior across nations.
