Can synchrony in stimulation guide attention and aid perceptual performance? We tested the influence of visual and auditory synchrony on attentional selection during a novel human foraging task involving multiple targets. We present results from a set of different tasks which all involve foraging for multiple targets on each trial. The visual stimuli ranged from lines changing color periodically to complex biological motion stimuli. We tested whether the synchronous change of targets (e.g. lines changing color from blue to yellow, or small dot rotating on a circle) aided foraging performance compared to when they changed asynchronously. We then also tested whether a non-spatial sound that occurred synchronously with the changes of the targets aided foraging performance (e.g. footstep sounds in synchrony with a point-light walker figure). The different experiments generally revealed benefits from visual synchrony, while the benefits from concurrent non-spatial sounds only occurred when participants directly foraged for the tempo of the changing stimuli. Our results demonstrate, across a number of tasks, that cross-modal cues to synchrony can be used to improve multitarget foraging, provided that synchrony itself is a defining feature of the target identity.
