Event Abstract Back to Event Dissociating the neural mechanisms underlying spatiotopic and retinotopic inhibition of return: An investigation using eye tracking and electroencephalography Jason Satel1*, Matthew D. Hilchey2, Zhiguo Wang3 and Raymond M. Klein2 1 University of Nottingham Malaysia Campus, School of Psychology, Malaysia 2 Dalhousie University, Department of Psychology and Neuroscience, Canada 3 Hangzhou Normal University, Center for Cognition and Brain Disorders, China Inhibition of return (IOR) is a behavioral phenomenon wherein responses are inhibited to stimuli at locations that have been previously attended. To investigate the neural reference frame of IOR, an eye movement must be introduced between stimulus onsets. Previous work has demonstrated that IOR is represented in spatiotopic, rather than retinotopic, coordinates [Maylor & Hockey (1985). Inhibitory component of externally controlled covert orienting in visual space. J Exp Psychol Hum Percept Perform, 11, 777-787]. Event-related potentials (ERPs) have further demonstrated that reductions in the early sensory P1 component are associated with retinotopic, but not spatiotopic, cueing - even though IOR is only present for spatiotopic cueing [Satel, Wang, Hilchey, & Klein (2012). Examining the dissociation of retinotopic and spatiotopic inhibition of return with event-related potentials. Neurosci Lett, 52, 40-44]. Here, we have expanded on previous designs by incorporating: 1) online eye tracking to ensure appropriate oculomotor behavior throughout trials, 2) both upper and lower visual field starting positions to avoid confounds associated with differential processing across hemifields, 3) an early eye movement condition to compare IOR when cueing is retinotopic, spatiotopic, and overlapping, 4) catch trials to discourage anticipatory responses, and 5) early target trials to ensure attention is not entirely focused upon central fixation during cue onset. Results show the expected pattern of spatiotopic IOR (11 ms, p < 0.01) without P1 reductions, non-significant retinotopic IOR (6 ms, ns) with P1 reductions, and strong IOR (43 ms, p < 0.001) with P1 reductions when retinotopic and spatiotopic representations overlap. These results continue to support the hypothesis that IOR is represented in spatiotopic coordinates and that retinotopic IOR is simply a remnant of repeated sensory stimulation in retinotopic coordinate space.
