Athletes' Use Of Imagery In The Off-Season, Jennifer Cumming, Craig Hall
Athletes' Use Of Imagery In The Off-Season, Jennifer Cumming, Craig Hall
Jennifer Cumming
The purpose of this study was to examine the influence of competitive level on an athletes’ use of imagery in the off-season, and to examine whether their use of imagery was related to their physical and technical preparation. Three hundred and twenty-four regional, provincial, and national level athletes were recruited to participate in this study from 10 different sports. Participants were asked to complete a modified version of the Sport Imagery Questionnaire (SIQ; Hall, Mack, Paivio, & Hausenblas, 1998) that was designed to reflect an athletes’ use of imagery in the off-season. MANOVAs indicated that competitive level differences existed in …

Ethological Causes And Consequences Of The Stress Response, Neil Greenberg, James A. Carr, Cliff H. Summers
Neil Greenberg
Stress involves real or perceived changes within an organism or in the environment that activate an organism’s attempts to cope by means of evolutionarily ancient neural and endocrine mechanisms. Responses to acute stressors involve catecholamines released in varying proportion at different sites in the sympathetic and central nervous systems. These responses may interact with and be complemented by intrinsic rhythms and responses to chronic or intermittent stressors involving the hypothalamic-pituitary-adrenal axis. Varying patterns of responses to stressors are also affected by an animal=s assessment of their prospects for successful coping. Subsequent central and systemic consequences of the stress response include …

Ethological Aspects Of Stress In A Model Lizard, Anolis Carolinensis, Neil Greenberg
Neil Greenberg
Research on the stress response in reptiles can provide a useful comparative perspective for understanding how the constituent elements of the response can be put into service of diverse behavioral adaptations. A summary of the neural and endocrine causes and consequences of specific behavioral patterns seen in the small diurnal lizard, Anolis carolinensis, has provided a model for the exploration of the dynamics of autonomic and neurohormonal contributions to adaptive behavior. In this species, changes in body color provide indices of the flux of circulating stress relevant hormones, and are seen in situations from spontaneous exploration through agonistic behavior. Furthermore, …
Adaptive Functions Of The Corpus Striatum: The Past And Future Of The R-Complex, Neil Greenberg
Adaptive Functions Of The Corpus Striatum: The Past And Future Of The R-Complex, Neil Greenberg
Neil Greenberg
The basal ganglia is emerging from the shadow cast by the most conspicuous clinical expression of its dysfunction: motor disorders.What is revealed is the nexus of a widely distributed system which functions in integrating action with cognition, motivation, and affect. Prominent among non-motor functions are striatal involvement in building up of sequences of behavior into meaningful, goal-directed patterns and repertoires and the selection of appropriate learned or innate sequences in concert with their possible predictive control. Further, striatum seems involved in declarative and strategic memory (involving intentional recollection and the management of retrieved memories, respectively). Findings from reptile experiments indicate …
