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.

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.
