Abstract
Previous studies suggest the existence of facilitatory effects between, for example, responding upwards/downwards while hearing a high/low-pitched tone, respectively (e.g., Rusconi et al., 2006; Occeli, Spence & Zampini, 2009). Neuroimaging research has started to reveal the activation of parietal areas (e.g., the intraparietal sulcus, IPS) during the performance of various pitch-based musical tasks (see Foster & Zatorre, 2010a, 2010b). Since several areas in the parietal cortex (e.g., the IPS; see Chica et al., 2011) are strongly involved in orienting visual attention towards external events, we investigated the possible effects of perceiving pitch-varying stimuli (i.e., ‘ascending or ‘descending’ flutter sounds) on the spatial processing of visual stimuli. In a variation of the Posner cueing paradigm (Posner, 1980), participants performed a speeded detection task of a visual target that could appear at one of four different spatial positions (two above and two below the fixation point). Irrelevant ascending (200-700Hz) or descending (700-200Hz) flutter sounds were randomly presented 550ms before the onset of the visual target. According to our results, faster reaction times were observed when the visual target appeared in a position (up/down) that was compatible with the “pitch direction” (ascending or descending) of the previously-presented auditory “cuing” stimulus. Our findings suggest that pitch-varying sounds are recoded spatially, thus modulating visual spatial attention.
