Abstract

Correctly processing rapid sequences of sounds is essential for developmental milestones, such as language acquisition. We investigated the sensitivity of two-month-old infants to violations of a temporal regularity, by recording event-related brain potentials (ERPs) in an auditory oddball paradigm from 36 waking and 40 sleeping infants. Standard tones were presented at a regular 300 ms inter-stimulus interval (ISI). One deviant, otherwise identical to the standard, was preceded by a 100 ms ISI. Two other deviants, presented with the standard ISI, differed from the standard in their spectral makeup. We found significant differences between ERP responses elicited by the standard and each of the deviant sounds. The results suggest that the ability to extract both temporal and spectral regularities from a sound sequence is already functional within the first few months of life. The scalp distribution of all three deviant-stimulus responses was influenced by the infants’ state of alertness.
Highlights
► Two-month-old infants were tested with an auditory event-related potential paradigm.
► A repeating sound was occasionally exchanged for a different sound, i.e. a deviant.
► Mismatch responses were elicited not only by spectral but also by temporal deviants.
► Temporal deviants were affected by state of alertness mostly on negative-going waves.
► Spectral deviants were affected by state of alertness mostly on positive-going waves.
