The purpose of this study is to provide information about how the brain processes sensory inputs using visual stimuli throughout various psychophysical experiments.
This laboratory studies visual perception with a focus on the interaction between eye movements and attention. It is well established that attending to a stimulus can profoundly alter perception. For example, attending to a speaker at a crowded party can almost completely filter background both in terms of auditory noise and visual distractions. Although laboratory studies have traditionally investigated the effects of attentional changes in the absence of eye movements, under natural conditions, visual attention is often accompanied by orienting movements to direct our head and eyes towards t…
Inclusion Criteria: * Age between 18-65 * Corrected-to-normal vision * No known diagnosis of visual or auditory disorder or impairment Exclusion Criteria: * Does not have corrected-to-normal vision * Unable to understand and follow the instructions given of the study * Known diagnosis of visual or auditory disorder or impairment
During behavioral sessions, subjects will sit in a dark room and view a video monitor placed at the minimum of 57 cm distance away from the subject. Staff will be present throughout all the testing to assist the subject and monitor equipment that is used for tracking their eye position. Subjects will be asked to maintain their heads in a stable position of rest in order to insure accurate tracking of their eye position. To stabilize their head, subjects will either use a "chin rest" in which they position their chin on a soft pad mounted in front of a video screen, or they may use a "bite bar."
