Fig. 1.

a A schematic illustration of a trial. Lights were presented with a particular SOA ranging between −75 and 75 ms, with negative values indicating that the lower light was presented first. Two capture sounds were presented either simultaneously with the lights (∼0 ms AV-interval), or ∼100 ms before the first and ∼100 ms after the second light (∼100 ms AV-interval). The capture sounds were embedded in a sequence of flanker sounds which either had the same or a different frequency (Exp1), rhythm (Exp 2), or location (Exp 3). Perceptual grouping of the sounds is illustrated by the grey ovals. Temporal ventriloquism only occurred when the capture sounds were different from the flanker sounds at the ∼100 ms interval, as illustrated on the second line. b Schematic set-up of Experiment 1, 2 and 3
