MMN is an ERP component that reflects preattentive discrimination between a recurring standard sound and a deviating sound. MMN is frequently used in infant studies focused on speech development since its elicitation does not require the attention of the child. The general ability of infants to discriminate speech sounds is gradually specialized towards discrimination of phonetic contrasts in their mother tongue. The aim of the present study was to examine if an MMN response is elicited by naturally varying speech stimuli (/ ti/ and / ki/) and if this response is stronger for the speech sound that infants typically produce at this age (/ t/). An EEG experiment with an oddball paradigm was designed. Participants were 19 infants (9-mo). An MMN-like negative response to deviants compared to standards was found, however it was not statistically significant. No significant interaction effect was found for MMN and type of deviant stimulus. Variation in the standard stimuli may have contributed to the lack of effect. It is also possible that the infants already were equally competent in discriminating both speech sounds, which may account for the small difference between the deviant waveforms.
