What causes individuals to hurt others? Since the famous case of Phineas Gage, lesions of the ventromedial prefrontal cortex (VMPFC) have been reliably linked to physically aggressive behavior. However, it is unclear whether naturally-occurring deficits in VMPFC, among normal individuals, might have widespread consequences for aggression. Using voxel based morphometry, we regressed gray matter density from the brains of 138 normal female and male adults onto their dispositional levels of physical aggression, verbal aggression, and sex, simultaneously. Physical, but not verbal, aggression was associated with reduced gray matter volume in the VMPFC and to a lesser extent, frontopolar cortex. Participants …
Dominance And Leadership: Useful Concepts In Human-Horse Interactions?, Elke Hartmann, Janne W. Christensen, Paul Mcgreevy
Dominance And Leadership: Useful Concepts In Human-Horse Interactions?, Elke Hartmann, Janne W. Christensen, Paul Mcgreevy
Animal Training and Obedience Collection
Dominance hierarchies in horses primarily influence priority access to limited resources of any kind, resulting in predictable contest outcomes that potentially minimize aggressive encounters and associated risk of injury. Levels of aggression in group-kept horses under domestic conditions have been reported to be higher than in their feral counterparts but can often be attributed to suboptimal management. Horse owners often express concerns about the risk of injuries occurring in group-kept horses, but these concerns have not been substantiated by empirical investigations. What has not yet been sufficiently addressed are human safety aspects related to approaching and handling group-kept horses. Given …
Reducing Adolescent Anger And Aggression With Biofeedback: A Mixed-Methods Multiple Case Study, Jedidiah S. Savard
Reducing Adolescent Anger And Aggression With Biofeedback: A Mixed-Methods Multiple Case Study, Jedidiah S. Savard
Antioch University Dissertations & Theses
Adolescent anger, aggression, and violent outbursts are social problems significantly affecting each of us. Individual therapeutic management of pathological anger is treated in various ways depending on practitioners’ theoretical orientations and competency levels. Popular psychological individual and group therapies addressing anger and aggression in adolescents focus primarily on cognitive-behavioral techniques that manage anger’s symptoms. Evidence-based cognitive-behavioral therapies often require clients to self-identify emerging antecedents of anger without assistance; such therapies employ predetermined strategies to assist the client to emotionally de-escalate prior to an angry or aggressive episode. However, cognitive responses to an emotional upheaval stemming from an emergence of anger …
Behavioral Interventions That Treat Aggression: Employees Implementation Experiences Within Adult Psychiatric Settings, Alyse Catherine Donovan
Behavioral Interventions That Treat Aggression: Employees Implementation Experiences Within Adult Psychiatric Settings, Alyse Catherine Donovan
Antioch University Dissertations & Theses
When adults hospitalized within inpatient psychiatric settings engage in aggressive behavior, it can have detrimental psychological and physical effects on not only other patients, but on hospital employees. Several adult psychiatric inpatient facilities have successfully reduced rates of patient aggression through the implementation of behavioral interventions. While there is much research on factors that lead to successful implementation of evidence based interventions, the literature had not yet explored the subjective experience of employees who are asked to implement behavioral plans in adult psychiatric settings. This study utilized Interpretive Phenomenological Analysis to gain an understanding of employees’ perceptions of barriers and …
