An examination of various aspects of auditory processing in clutterers

This study examined auditory processing ability in three school-aged male clutterers who presented concomitant diagnoses of attention deficit disorder (ADD) and three age- and sex-matched normal-speaking control subjects. Subjects underwent a brief central auditory processing (CAP) and auditory event-related potential (AEP) battery. All three clutterers performed below normal test-established performance criteria on at least two of the four CAP measures and exhibited abnormal AEP waveform morphology. All control subjects performed within normal test-established performance criteria on all measures.
