How Actions Change What We See (Maybe): The Effect of Visuomotor Action Preparation on Visual Crowding

Description

Abstract:
Crowding is a phenomenon of peripheral vision where a collection of objects can be detected, but not discriminated. When only one object is in the periphery, perception is nearly completely intact. Upon addition of neighboring objects, however, features and edges seem jumbled, which may occur due to lower attentional resolution in the periphery. Action preparation also modulates attention, but it is currently unclear how it influences crowding. This experiment assesses whether it can change the severity of the crowding effect. I will measure subjects’ sensitivity to orientation change in the periphery, then determine whether sensitivity changes upon grasping the stimulus. As crowding is a form of nonconscious vision that affects behavior, it has implications in the formation of implicit biases.
