Study on the Effects of Exogenous Testosterone on Threat Perception and Behavioral Avoidance

The study aims to establish a clear causal link between testosterone and threat perception and behavioral responses to threat. Namely, the study focuses whether high levels of testosterone will cause an individual to exhibit increased physiological responses to threat (e.g., increased blood pressure, heart rate, and endocrine responses) and a decreased behavioral response (e.g., ignoring the threat, avoiding the threat, and postponing dealing with the threat). The threat in this study is a social threat involving public speaking, and is an outgrowth of previous research on the avoidance of health threats.
