Research Abstract

The aim of this project was to clarify the influence of categorical speech perception on the representation of phonemes in the auditory cortex measured with psychophysics and magnetoencephalography (MEG). We observed a larger behavioral categorical effect for consonants than for vowels. Furthermore, MEG revealed suppression effects for repetition of same compared to different phonemes predominantly in the left cortical hemisphere.
