Improvements in performance on visual tasks due to practice are often specific to a retinal position or stimulus feature. Many researchers suggest that specific perceptual learning alters selective retinotopic representations in early visual analysis. However, transfer is almost always practically advantageous, and it does occur. If perceptual learning(More)
Perceptual learning, the improvement in performance with practice, reflects plasticity in the adult visual system. We challenge a standard claim that specificity of perceptual learning depends on task difficulty during training, instead showing that specificity, or conversely transfer, is primarily controlled by the precision demands (i.e., orientation(More)
This exploratory study aims to establish the feasibility of an Ashtanga-based Yoga Therapy (AYT) program for improving sleep disturbances , balance, and negative psychosocial states, which are prevalent issues for visually impaired (VI) individuals. Ten legally blind adult participants were randomized to an 8-week AYT program. Four subjects in the 1 st(More)
Individuals with visual impairment (VI) have irreparable damage to one of the input streams contributing to postural stability. Here, we evaluated the intra-session test-retest reliability of the Wii Balance Board (WBB) for measuring Center of Pressure (COP) magnitude and structure, i.e. approximate entropy (ApEn) in fourteen legally blind participants and(More)
Purpose Law enforcement ranks as one of the most stressful occupations in the world. Police Academy training does not prepare recruits to handle chronic occupational stress, which is known to lead to adverse health outcomes , such as depression and maladaptive behaviors. Yoga is a mind-body practice composed of postures, breathing, and meditation techniques(More)
