Abstract	The aim of the present study was to explore the spatial organization of auditory time and the effects of the manipulation of spatial attention on such a representation. In two experiments, we asked 28 adults to classify the duration of auditory stimuli as "short" or "long". Stimuli were tones of high or low pitch, delivered left or right of the participant. The time bisection task was performed either on right or left stimuli regardless of their pitch (Spatial experiment), or on high or low tones regardless of their location (Tonal experiment). Duration of left stimuli was underestimated relative to that of right stimuli, in the Spatial but not in the Tonal experiment, suggesting that a spatial representation of auditory time emerges selectively when spatial-encoding is enforced. Further, when we introduced spatial-attention shifts using the prismatic adaptation procedure, we found modulations of auditory time processing as a function of prismatic deviation, which correlated with the interparticipant adaptation effect. These novel findings reveal a spatial representation of auditory time, modulated by spatial attention. (Contains 4 figures.) (As Provided).
