Self-Construal Moderates Testosterone Reactivity To Competitive Outcomes, Keith Welker
Self-Construal Moderates Testosterone Reactivity To Competitive Outcomes, Keith Welker
Wayne State University Dissertations
Previous research shows that testosterone reactivity to competitive outcomes predicts aggressive behavior in men. However, some studies have failed to find these effects, and it has been suggested that individual differences moderate the relationships between competitive outcomes, testosterone fluctuations, and aggressive behavior. The current research examined whether one individual difference--self-construal--would moderate these effects. In Study 1, participants were assigned to win or lose a competitive video game and engaged in a reactive aggression task. Results indicated that increases in testosterone in response to winning and decreases in response to losing occurred in men with independent, not interdependent, self-construals. These changes …
The Effects Of Men's Acute Alcohol Intoxication, Overperception Of Sexual Intent, Interpersonal Rejection And Testosterone On Aggression Toward Women, Rhiana Marie Wegner
The Effects Of Men's Acute Alcohol Intoxication, Overperception Of Sexual Intent, Interpersonal Rejection And Testosterone On Aggression Toward Women, Rhiana Marie Wegner
Wayne State University Dissertations
This study was designed to assess Abbey's (1991; 2002; 2011) model, which posits that acute alcohol intoxication increases the likelihood of sexual aggression at two stages of a cross-sex interaction. Early on, the cognitive impairments induced by alcohol encourage a potential perpetrator to overperceive a woman's level of sexual intent. Later, if the man's sexual advances are rejected, intoxication encourages an aggressive response. This research expands on the previous literature by examining: 1) both stages of Abbey's model in a single study, 2) rejection from a woman as a potential trigger for aggression, and 3) behavioral (past sexual assault perpetration), …
Friend Or Foe: The Effect Of Shared Group Status On Aggressiveness And Testosterone In Response To Provocation, Eric William Fuller
Friend Or Foe: The Effect Of Shared Group Status On Aggressiveness And Testosterone In Response To Provocation, Eric William Fuller
Wayne State University Dissertations
Previous research has found that individuals display behavioral and hormonal differences when engaged in competition with natural and experimental ingroup and outgroup members. The current work expands on this line of research by examining the impact of shared group status on reactive aggression in response to provocation. Using a previously validated measure of reactive aggression, participants were provoked by and given a chance to aggress on to either a racial ingroup or outgroup member. Participants also provided saliva samples to allow for monitoring changes in testosterone. It was hypothesized that behavioral aggression would be predicted by changes in testosterone and …
