Brief Summary:
In this study, we will use behavioral methods to investigate several types of interactions that occur when visual stimuli conflict, such as when objects are presented nearby to each other, or to separate eyes. We will target purely sensory aspects by using simple geometric shapes: letters and lines. Our outcome measure will be performance thresholds.
Detailed Description:
Participants will be shown visual stimuli on displays and be asked to identify some aspect of the stimuli: their orientation and/or color, the existence of binocular suppression, etc.
In different blocks, stimuli will be manipulated in different ways to characterize basic aspects of visual processing. For example, the contrast, color, and/or spatial layout of stimuli will be varied.
