P2.1 Virtual Reality modulates Vestibular Brain Responses Gallagher, M., Dowsett, R. & Ferrè, E.R. Royal Holloway University of London [show_more more="Show abstract" less="Hide abstract"]Virtual reality (VR) has become increasingly popular in the past decade. Key to the user's VR experience are multimodal interactions involving all senses. However, sensory information for self-motion is often conflicting in VR: while vision signals that the user is moving in a certain direction with a certain acceleration (i.e. vection), the vestibular organs provide no cues for linear or angular acceleration. To solve this conflict, the brain might down-weight vestibular signals. Here we recorded participants' physiological responses to actual vestibular events while being exposed to VR-induced vection. We predicted that exposure to a few minutes of linear vection would modulate vestibular processing. Vestibular-evoked myogenic potentials (VEMPs)…

P1.1 The prevalence of between-hands spatial codes in a tactile Simon task Gherri, E., & Theodoropoulos, N. University of Edinburgh [show_more more="Show abstract" less="Hide abstract"]When a tactile stimulus is presented to our body, its spatial location is automatically coded, modulating behavioural performance, even when space is completely task-irrelevant (Tactile Simon effect). Here we present a series of studies investigating whether multiple spatial codes are created for the location of tactile stimuli in a tactile Simon task. In the two hands task (Exp. 1 and 3), in which stimuli were presented to one of four possible locations (left and right finger on the left and right hand), the tactile target was automatically coded according to the location of the stimulated hand (between-hands Simon effect) but not according to the location of…
