Testosterone Might Not Be Necessary To Support Female Aggression In Incubating Northern Cardinals, M. Susan Devries, Caitlin P. Winters, Jodie M. Jawor Sep 2015

Testosterone Might Not Be Necessary To Support Female Aggression In Incubating Northern Cardinals, M. Susan Devries, Caitlin P. Winters, Jodie M. Jawor

Faculty Publications

Testosterone's (T) influence on male aggression has been well established in many vertebrate species, but the impact of T on female aggressive behaviour is poorly understood. Among birds, a link between T and female aggression is plausible, as females of many species exhibit a seasonal peak in T concentrations at the onset of breeding when social instability is greatest and they may have circulating T through much of the breeding season. However, investigations examining the relationship between T and female aggression are few and have yielded conflicting results, with experimentally or endogenously elevated T supporting aggressive behaviour in females of …


Cybervictimization As A Predictor Of Aggression And Cyberbullying Among Adolescents: Examination Of Potential Risk And Protective Factors, Laura Ashley Cook Aug 2015

Cybervictimization As A Predictor Of Aggression And Cyberbullying Among Adolescents: Examination Of Potential Risk And Protective Factors, Laura Ashley Cook

Dissertations

The current study examined how cybervictimization is related to aggression outcomes among adolescents. The current study also examined various potential risk and protective factors, including depressive symptoms, anger rumination, impulsivity, social support, and gender. It was hypothesized that the relation between cybervictimization and aggression or cyberbullying would be intensified when levels of depressive symptoms, impulsivity, and anger rumination were higher and that the relation between cybervictimization and aggression or cyberbullying would be attenuated when levels of social support were higher. Gender was examined as a research question, with no specific directionality hypothesized. The data for the current study were collected …


Personality And Relational Aggression In College Students: The Role Of Social Anxiety And Rejection Sensitivity, Daniel Locke Deason May 2015

Personality And Relational Aggression In College Students: The Role Of Social Anxiety And Rejection Sensitivity, Daniel Locke Deason

Master's Theses

Relational aggression involves the intentional infliction of harm via damaging one’s relationships or sense of belonging. Previous research suggests that relational aggression among children and early adolescents is correlated with social ostracism, poor psychological adjustment, anxiety, and depression in victims, and there is increasing evidence that many of these correlates apply to relational aggression among older adolescents and emerging adults. Efforts to identify predictors of relational aggression are underway; however, many variables which have been influential in understanding other forms of aggression have not yet been examined. The Five Factor Model (FFM) of personality is one example, as it has …
