Summary

The ability to judge the locations of various objects from oneself during self-motion in the intermediate distance range (\~2-25m) is crucial for successful performance of activities of daily living, such as walking and driving. However, little is known about the mechanisms of visual space perception involved in judging distance, the focus of this project, in the planning and/or execution of self-motion in the natural 3D environment. The theoretical knowledge to be gained from this project will contribute to the scientific literature and provide insights into how eye and neurological defects could impair visual space perception, wayfinding, and mobility.

Conditions

  • Vision

Interventions

OTHER

Visual Stimuli for Space Perception

The visual environment (e.g., target locations and texture backgrounds) will be varied and human behavioral responses (judged distances) will be measured to reveal the space perception and cognitive processes underlying space perception and navigation.
