Physical Fatigue Negatively Affects Decision-Making During A Closing-Gap Aperture Crossing Task When Using Joystick-Controlled Locomotion, Natalie Snyder
Physical Fatigue Negatively Affects Decision-Making During A Closing-Gap Aperture Crossing Task When Using Joystick-Controlled Locomotion, Natalie Snyder
Theses and Dissertations (Comprehensive)
Goal-direct locomotion is made possible through the integration of sensory input from the visual, vestibular, and somatosensory system. However, changes in collision avoidance behaviours and action capabilities (i.e., affordances) may occur when a sensory conflict is introduced (i.e., via incongruent input from a sensory system). Further, changes to the person (such as physical fatigue) may have negative implications on the cognitive abilities of an individual following physically fatiguing exercise. This in turn could affect an individual’s ability to avoid collisions with objects or other individuals in their environment. Thus, the objective of this thesis was to explore how physical fatigue …
The Effect Of Gvs On Path Trajectory And Body Rotation In The Absence Of Visual Cues During A Spatial Navigation Task, Tanya Karn
Theses and Dissertations (Comprehensive)
Background: The vestibular system has been shown to contribute to mechanisms of locomotion such as distance perception. Galvanic vestibular stimulation (GVS) is a tool used to perturb the vestibular system, and causes significant deviations in path trajectory during locomotion. Previous research has suggested that applying GVS during straight-line locomotion tasks is not sufficient to determine the effects of the vestibular system on locomotion. However, spatial navigation challenges one’s ability to navigate throughout the environment using idiothetic cues to constantly update one’s position. The purpose of the current study was to determine the effects of GVS on both path trajectory and …
