Effects Of Positive Social Comparative Feedback During Practice On Motor Sequence Learning, Performance Expectancies, And Resting State Connectivity, Allison Foster Lewis

Theses and Dissertations

Positive social comparative feedback indicates to the learner that they are performing better than others. While this type feedback supports motor skill learning in some tasks, the effect of social comparative feedback on motor sequence learning remains unknown. In addition, the OPTIMAL theory predicts that positive social comparative feedback may trigger a dopaminergic response in the brain. However, no studies have utilized neuroimaging techniques to investigate this question. Therefore, the aim of these studies was to determine the effect of positive social comparative feedback on motor sequence learning, performance expectancies, and resting state connectivity of dopaminergic neural pathways.

The Effects Of A Game Simulation On Muscle Activation And Knee Kinematics In Females, Geoffrey Collins

Theses and Dissertations

Intro: Female athletes experience non-contact ACL injuries at 5 times the rate of male athletes. These injuries occur more frequently at the end of halves and may be associated with exercise-induced fatigue causing knee instability. The purpose of this pilot study was to determine the effect of strenuous exercise on lateral knee movement during the landing phase of a jump. Methods: Ten subjects completed both the exercise and the control trial consisting of two 25-min game simulations on a treadmill or on a separate day the equivalent rest. Before, at half time, and immediately following the interventions subjects performed sets …
