The Role Of Athletic Scholarship On Suboptimal Performance In Baseline Concussion Testing, Lauren E. Goworowski
Theses and Dissertations
Objective: To date, there is a very limited amount of research regarding the topic of sandbagging (i.e., intentional poor performance) during concussion baseline testing in a collegiate athlete population. It is known that student-athletes may underreport their concussive symptoms so they can return to play more quickly, and may purposefully lower their baseline results to appear less impaired following a head injury so as to avoid exclusion from play (Echemendia & Cantu, 2003; Reilly 2011). At this point in time, it is difficult to make statements regarding sandbagging because the incidence of this behavior is unknown. Accordingly, this study had …
Effort-Related Motivational Dysfunctions: Behavioral And Neurochemical Studies Of The Wistar-Kyoto Rat Model Of Depression, Brendan Abbott
Effort-Related Motivational Dysfunctions: Behavioral And Neurochemical Studies Of The Wistar-Kyoto Rat Model Of Depression, Brendan Abbott
Masters Theses
Depression and related disorders are characterized by motivational dysfunctions, including deficits in behavioral activation and exertion of effort. Animal models of relevance to depression represent a critical starting point in elucidating the neurobiological mechanisms underlying motivational dysfunctions. The present study explored the use of the Wistar-Kyoto (WKY) animal model of depression to examine effort-related functions as measured by voluntary wheel running and performance on a mixed fixed ratio 5/progressive ratio (FR5/PR) operant task. Given the known link between activational aspects of motivation and the mesocorticolimbic dopamine (DA) system, the behavioral effects of d-amphetamine (0.5 and 1.0 mg/kg, IP), a psychostimulant …
