Attention and Interocular Competition

Visual attention functions to select relevant information for further processing among vast amounts of visual input, and attention is generally important for resolving stimulus ambiguities and competitions. I will describe three sets of experiments investigating the interaction between attention and interocular competition. First, using continuous flash suppression to render images invisible, we demonstrated that observers’ spatial attention could be guided by interesting but invisible images. Second, our behavioral experiments revealed that voluntary attention can be eye-specific, modulating visual processing within a specific monocular channel, despite that fact that observers normally do not have explicit access to the eye-of-origin information. Third, using an EEG frequency-tagging method to track cortical representation of dichoptically presented images, we showed that when attention was diverted away from the competing stimuli, binocular rivalry ceased and interocular c ompetition remain unresolved.
