The auditory system analyzes sound structure in a complex way to arrive at perceiving and representing pitch. Some theories suggest that learning plays an important role in pitch perception. Therefore we tested whether or not nontrivial forms of pitch analysis are functional in newborn infants, especially because pitch processing is an important prerequisite of music and speech perception and is also crucial for representing auditory objects. In two separate studies we investigated 1) whether or not newborn infants generalize pitch across different timbres and 2) whether the auditory system of newborns extracts the constancy of a pitch interval from exemplars varying in absolute pitch. In both experiments we recorded event-related brain potentials in healthy newborn infants to frequent standard and infrequent deviant sound stimuli. In study 1) timbre-independent pitch representation was tested by a paradigm where we applied randomly varying tones of different perceived resonator size, which is an aspect of timbre that informs the listener about the size of the sound source. The elicitation of an early negative and a later positive discriminative response by deviant sounds demonstrated that the neonate auditory system represents pitch separately from timbre. In study 2) we investigated whether the auditory system of newborns extracts the constancy of a pitch interval from exemplars varying in absolute pitch. To this end we applied an oddball paradigm consisting of frequent standard and infrequent deviant tone pairs. Tone pairs varied in absolute frequency. Standard and deviant pairs differed in the amount of pitch difference within the pairs, but not in the direction of pitch change. Deviant tone pairs elicited a discriminative ERP response, suggesting that the neonate auditory system represents pitch intervals similarly to adults. Our results demonstrate that adult-like pitch processing abilities are present already at birth and they allow newborn infants to learn music, speech prosody, and to process various important auditory cues based on spectral acoustic features.
