Recently more and more studies test the interactions between the visual and olfactory systems. In their present paper the authors studied the effect of an odorous male gender specific sex-hormone - like steroid (5-alpha-androgenst-16-en-3-one) on face perception of healthy adult males in a two-alternative forced-choice gender discrimination task. According to their results subjects judge a particular face significantly more male when inhaling the steroid, than in the control condition. The authors' experiments illustrate that the olfactory presentation of sex-hormone - like steroids can alter the sexual discrimination of faces in a symmetric way, consequently there is a close interaction between olfactory and visual modalities, and this relationship manifests on socially important odorous substances and human faces.

The present study focused on the relationship between salivary testosterone levels and cognitive styles of empathizing and systemizing in children with Asperger syndrome (AS). Fifty AS boys from Slovakia in the range from 6 to 18 years participated in the research. The control group consisted of 79 age/sex-matched boys from primary and grammar schools. Participants were divided into a pre-pubertal and pubertal group. The measures of empathizing/systemizing as well as additional measures (intuitive physics and folk psychology) were used. The group of AS boys scored lower in empathizing measures compared to the control boys. The pre-pubertal AS group was more systemized than their control peers. Salivary testosterone levels were lower in AS group. The study found positive correlation between salivary testosterone and folk psychology, and revealed a negative correlation between salivary testosterone and intuitive physics in pubertal boys. These findings are discussed with reference to the 'extreme male-brain' theory of autism.
