It is well-established that males of many nonhuman vertebrate species exhibit hormonal
reactions to stimuli from potential mates. The present studies were designed to test …

Recent research suggests that cortisol (C) level moderates testosterone (T) reactivity to the
Trier Social Stress Test (TSST) in men. The extent to which C moderates T reactivity in other …

Rapid testosterone fluctuations in response to social stimuli are observed across a wide
range of species, and the highly conserved nature of these fluctuations suggests an …

The dual hormone hypothesis posits that basal cortisol and testosterone have a joint effect
on motivational and behavioral systems implicated in dominance and aggression, such that …

Eisenegger and colleagues [1] recently published in this journal an important review on the
role of testosterone (T) in social interaction. We agree with the main premise of the article …

The steroid hormones, testosterone and cortisol, have some common characteristics, but
they are related to generally antagonic processes at both the physiological and …

The gonadal hormone testosterone is well-recognized to facilitate various behaviors for
obtaining social status. A good reputation (ie competitive, generous, and trustworthy) is of …

Research has suggested that stressful situations lead to a decrease in testosterone,
whereas concern with one's social status increases testosterone. However, results from …

Recent research suggests that when we lack a sense of control, we are prone to
motivational failures and early quitting in competitions. Testosterone, on the other hand, is …

Although androgens are widely studied in the context of aggression, androgenic influences
on prosocial behaviours have been less explored. We examined testosterone's (T) influence …
