Current Research: Professor Witt studies how a person's ability to act influences perception. For example, baseball players who are hitting well see the ball as bigger. People who are fatigued or out of shape see hills as steeper. Objects that are within reach look closer. These findings demonstrate an important role of action in the basic processes of perception.

Jessica Witt's Action-Specific Perception Lab: Dr. Witt studies how a personís ability to act influences their perception. For example, softball players who are hitting better than others see the ball as bigger. Objects that can be reached and grasped look closer and smaller. Targets that are easier to catch look slower. These studies show that perception is action-specific.
