Abstract
Auditory processing disorders (APDs) have received considerable attention over the past few decades. Much of the attention has focused on the controversy surrounding the operational definition of APD, the heterogeneous nature of APD, and an appropriate test battery for APD assessment. Temporal processing deficits are one characteristic of APD and are the focus of the present investigation. This investigation reports behavioral and early electrophysiological measures in a group of children with specific temporal processing difficulties and an age-matched control group. In an effort to better describe the subjects, two language tests and the SCAN-C were administered. Significant differences were found in the language tests, SCAN-C, and behavioral tests of temporal processing. No significant differences in ABR waveform latency were found between the control and experimental group. Significant amplitude differences were found, albeit small. Binaural interaction was present in both groups. Based on the results of the present well-controlled investigation of children with temporal processing disorders, there is no indication that the auditory brainstem response recording to click stimuli is efficient in providing additional diagnosis of APD.
