Amodal completion of acoustic signals by a nonhuman primate.
Evidence of amodal completion exists for both visual and auditory stimuli in humans. The importance of this mechanism in forming stable representations of sensory information suggests that it may be common among multiple modalities and species. Here we show that a species of nonhuman primate amodally completes biologically meaningful acoustic stimuli, which provides evidence that the neural mechanism mediating this aspect of auditory perception is shared among primates, and perhaps other taxonomic groups as well.
