Potential Factors Influencing Nest Defense In Diurnal North American Raptors, Joan L. Morrison, Madeline Terry, Patricia L. Kennedy
Potential Factors Influencing Nest Defense In Diurnal North American Raptors, Joan L. Morrison, Madeline Terry, Patricia L. Kennedy
Faculty Scholarship
Nesting habitat, predator type, and level of reproductive effort influence nest defense behaviors in many bird species, yet no study has examined these or other possible factors influencing nest defense in a cross-species comparison for raptors. Using data from the literature, we grouped the nest defense behaviors of 19 diurnal North American raptors into four categories based on a gradient of aggressiveness. For each species, we identified the cover types where nesting occurred, accessibility of nest location, assessed two indices of reproductive effort, and examined associations between these factors and nest-defense behavior. We also we examined responses by raptor species …
Corticotropin Releasing Factor Receptors And Agonistic Behavior In Syrian Hamsters, Alicia N. Faruzzi
Corticotropin Releasing Factor Receptors And Agonistic Behavior In Syrian Hamsters, Alicia N. Faruzzi
Psychology Dissertations
Social conflict is a part of everyday life, and it can be a potent stressor for both humans and other animals. In the laboratory, when two Syrian hamsters (Mesocricetus auratus) compete for territory, a dominance hierarchy is quickly formed. Becoming subordinate is a significant stressor resulting in increased release of adrenocorticotropic hormone, β-endorphin, and cortisol. Defeated hamsters will also subsequently fail to display territorial aggression in future social encounters and will instead display increased submissive behavior, even in the presence of a smaller, non-aggressive intruder. This change in behavior is consistent and long-lasting and has been termed conditioned defeat (CD). …
Real-Time Decision Making And Aggressive Behavior In Youth: A Heuristic Model Of Response Evaluation And Decision (Red), Reid Griffith Fontaine, Kenneth A. Dodge
Real-Time Decision Making And Aggressive Behavior In Youth: A Heuristic Model Of Response Evaluation And Decision (Red), Reid Griffith Fontaine, Kenneth A. Dodge
Reid G. Fontaine
Considerable scientific and intervention attention has been paid to judgment and decision-making systems associated with aggressive behavior in youth. However, most empirical studies have investigated social–cognitive correlates of stable child and adolescent aggressiveness, and less is known about real-time decision making to engage in aggressive behavior. A model of realtime decision making must incorporate both impulsive actions and rational thought. The present paper advances a process model (response evaluation and decision; RED) of real-time behavioral judgments and decision making in aggressive youths with mathematic representations that may be used to quantify response strength. These components are a heuristic to describe …
Applying Systems Principles To Models Of Social Information Processing And Aggressive Behavior In Youth, Reid G. Fontaine
Applying Systems Principles To Models Of Social Information Processing And Aggressive Behavior In Youth, Reid G. Fontaine
Reid G. Fontaine
Systems perspectives view development as the product of hierarchically-organized levels of varied life processes that are continually changing and interacting as time passes. This theoretical approach may be of considerable importance to developing research programs in child social cognition, particularly since multilevel, multiprocess models of social information processing and aggressive behavior in youth are still in relatively formative stages. This paper proposes that key systems principles can be conceptually applied to social information-processing models in ways that are critical to furthering future research in social–cognitive foundations of aggressive behavior. Examples of initial applications to current social information processing models of …
