Auditory Evoked Potentials, Auditory Processing Disorder, Frequency Discrimination, Mismatch Negativity, Specific Language Impairment
The purpose of this study was to determine if 10-12 year old children with Auditory Processing Disorder (APD) or Specific Language Impairment (SLI) could discriminate three different frequency changes behaviorally and electrophysiologically. Behavioral frequency discrimination and event-related potentials were examined using a 1000Hz pure tone base frequency. Typically developing children and children with APD or SLI differed in in their detection of frequency changes: behavioral results were below chance level and the MMN amplitude was smaller in the impaired population. Slight differences between children with APD and children with SLI were also found that might shed light on the controversy regarding the deficits underlying pediatric APD, either a disorder in itself, or a symptom of a higher information processing deficit.
