Treefrogs exploit temporal coherence to form perceptual objects of communication signals.

ABSTRACT: For many animals, navigating their environment requires an ability to organize continuous streams of sensory input into discrete 'perceptual objects' that correspond to physical entities in visual and auditory scenes. The human visual and auditory systems follow several Gestalt laws of perceptual organization to bind constituent features into coherent perceptual objects. A largely unexplored question is whether nonhuman animals follow similar Gestalt laws in perceiving behaviourally relevant stimuli, such as communication signals. We used females of Cope's grey treefrog (Hyla chrysoscelis) to test the hypothesis that temporal coherence-a powerful Gestalt principle in human auditory scene analysis-promotes perceptual binding in forming auditory objects of species-typical vocalization
