Perceiving is Believing: Understanding Verticality Perception, Navigation, and Motion Perception in Healthy and Impaired Populations

Perceiving is Believing: Understanding Verticality Perception, Navigation, and Motion Perception in Healthy and Impaired Populations

Objectives

Participants will be able to:

1. Describe the perceptual processes involved with normal balance, gait, and motion perception; 

2. Understand and apply strategies for assessment of multi-sensory perception in the context of common perceptual challenges; 

3. Understand and apply strategies for treatment of persons who present with common perceptual challenges; 

4. Utilize concepts from current research on perception and practical experience to develop clinically-relevant questions to guide future scientific inquiry and improve patient care.
