Fast parametric evaluation of central speech-sound processing and phoneme categorization of 11-12 year old children with the mismatch negativity of the auditory event related potential

Abstract

Event Abstract Back to Event Fast parametric evaluation of central speech-sound processing and phoneme categorization of 11-12 year old children with the mismatch negativity of the auditory event related potential Satu Pakarinen1*, Laura Sokka2 and Minna Huotilainen1 1 University of Helsinki, Finland 2 Finnish Institute of Occupational Health, Finland We used a multi-feature mismatch negativity (MMN) paradigm with different magnitudes of phonemic and prosodic sound changes for investigating the speech-sound discrimination and phoneme categorization in 11-12 year old typically developing children. The MMN responses were recorded to three magnitudes of vowel, vowel-duration, and intensity changes, as well as to two magnitudes of pitch changes from vowel /i:/ in 34 minutes. All MMNs were statistically significant, and the MMN amplitude increased with the magnitude of sound change. Moreover, the different types of sound changes were processed differently in relation to the sound-change magnitude. For instance, the MMN amplitude for the intensity change increased linearly as a function of sound-change magnitude, whereas the MMN amplitude for the vowel duration (significant in Finnish language) reflected also the quantity categorization to short and long vowels. Moreover, the relationship between the magnitude of stimulus deviance and the MMN amplitude was similar to that found previously in adults (Pakarinen et al., 2011). These results indicate that this paradigm produces reliable MMN responses and allows also investigation of phoneme categorization in school-aged children. Further, the results suggest that the central auditory speech processing is in many parts developed to its adult form already before the age of 11. With this MMN paradigm, one could follow the language development and specifically the evolution of phoneme categories already from birth, as well as during second and foreign language learning. Importantly, one could detect the possible deviations of auditory processing underlying speech and language disorders at very early stages, enabling corrective rehabilitation before the problems accumulate.
