Description:

This study is about the effects of adding a brief change in brightness/contrast to a stimulus during binocular rivalry. This research will enhance our understanding of the process of switches during binocular rivalry and how the duration of these switches can be impacted by changing the properties of stimuli. Participants will be asked to report their perception through keyboard presses through this in-person experiment in Elliott Hall, where the stimuli will be presented using mirrors and a computer monitor. Participants will also fill out consent and demographic forms, and will also be assessed for visual acuity and contrast sensitivity before the start of the experiment. Exclusion criteria include having any visual impairments or related disorders as well as being under the age of 18. The time commitment for this study will be 5 to 90 minutes per session, with the option to participate in multiple sessions (1 to 12 sessions total), for a total time commitment of up to 12 hours. Participants will receive REP points or $15/hour as compensation for participation. No direct risk or benefits from participation are expected in this study.
