Action-Specific Perception Lab

College of Natural Sciences

Welcome to the CSU Action-Specific Perception Lab

PI: Witt

Research in the Action-Specific Perception Lab focuses on how visual perception of spatial properties such as size, distance, and speed is influenced by the perceiver's ability to act on the target.  For example, softball players who are hitting better than others see the ball as bigger.  As another example, targets appear to be moving slower when they are easier to catch.  This research demonstrates that perception is action-specific, meaning that what is seen is specific to the observer's ability to perform the intended action.
