Abstrakt		Measuring the phoneme elicited mismatch negative (MMN) event-related potential component may provide a useful method for investigating intact and impaired feature processing of various speech sounds accompanying developmental and acquired language problems. The consonant-vowel (CV) syllable and vowel elicited MMN has a reliable power of differentiating between control and dyslexic children whose MMN shows amplitude distribution anomalies. The lack of MMN to CV deviation, particularly to that of place of articulation suggests a deficient representation of special consonant clusters. The total or unilateral disappearance of the phoneme elicited MMN is not related to a particular type of aphasia. However, the frequent disappearance of the MMN to voicing and place of articulation in Broca's aphasics suggests different generators being active in speech sound comparison and contributes to the motor theory of consonant processing.
