| summary | The age-old interest in consciousness and subjective experience has evolved in recent years into a major effort to discern the cognitive and neural mechanisms involved in perceptual awareness. What determines the content of our consciousness at any given time? And can meaningful perceptual processing occur for sensory stimuli that do not reach awareness? In this talk I will describe recent work in which I used interocular rivalry and suppression to address these related issues. The first part of the talk will focus on a series of transcranial magnetic stimulation (TMS) studies establishing the importance and specific roles of non-visual, high-level regions of parietal cortex in selecting sensory stimuli for conscious representation. The second part will go into an ongoing series of psychophysiological studies investigating the processing of emotional stimuli in the absence of awareness; this work demonstrates that conscious and unconscious processing differ qualitatively, not only in how they develop over time but also in the specific physiological responses each type of processing evokes. |
