More specifically, children (N = 167) participated in focus groups and completed open-ended questionnaires in order to provide information on their perceptions of cohesion as well as motives for participating, continuing, and ceasing involvement on sport teams. Study 2 involved the use of the information obtained from Study 1 to develop potential items for the questionnaire. In addition, the …

The Importance Of Self-Efficacy And Basic Psychological Needs In Children’S Physical Activity: Measurement, Prediction And Intervention, Casey E. Gray

Electronic Thesis and Dissertation Repository

The importance of physical activity in the overall health promotion and primary prevention of cardiovascular disease risk factors and metabolic diseases in children is well established. Nonetheless, interventions to increase physical activity among this population have been largely unsuccessful. The main objective of the research in this dissertation was to explore the suitability of self-efficacy and basic psychological needs for physical activity prediction and intervention in children. Item generation and psychometric evaluation of psychological questionnaires occurred in study 1 (Chapter 2). Using a prospective design, study 2 (Chapter 3) established task efficacy, barriers efficacy, competence, and autonomy as significant predictors …

Contextual Control Of Orienting Eye-Head Gaze Shifts In The Monkey, Brendan B. Chapman

Electronic Thesis and Dissertation Repository

Vision is one of the principal methods used by primates to acquire information about the surrounding environment. As a result, both humans and monkeys have a highly evolved oculomotor system that functions to rapidly relocate the line of sight to areas of interest.

This thesis examines the muscular and neural control of orienting head movements.

The contextual control of behavior is important as it allows one to act appropriately in response to different situations. A common task used to examine …
