Abstract: Many of our percepts of the world depend on the integration of information from our multisensory environment. Often this integration is facilitatory in nature, but under other conditions, sensory information can at times compete, leading to one sense attenuating processing in a separate sense. For instance, when presented with competing auditory and visual stimuli, adults tend to perceive the visual information more often than the auditory information. Indeed, the vast majority of sensory dominance investigations have suggested that vision often attenuates auditory processing. Interestingly, Robinson, Ahmar, and Sloutsky (2010) recently demonstrated the opposite; auditory dominance, suggesting multiple modality dominances may exist under varying conditions. However, their methodologies differed from traditional sensory dominance research as they did not require explicit responses from participants, and instead measured latency of specific event related potentials (ERP) components. Experiment 1 of the thesis replicated their findings by demonstrating auditory dominance in a modified, more explicit version of Robinson et al. (2010)'s paradigm. Experiment 2 further modified the experiment and displayed visual dominance once error rates were measured. Overall, the findings suggest that modality dominance type can be modulated in the same population under certain conditions.
