The purposes of the present investigation were: (1) to examine the order of report phenomenon in children both with and without suspected central auditory processing disorders (CAPD); (2) to define the presence of laterality effects through determining the relationship, if any, between order of report and hand dominance in children; and (3) to determine the clinical value, if any, of establishing degree of handedness to interpreting dichotic test results. Ten children with suspected CAPD and ten children with presumably normal central auditory nervous system (CANS) function were administered a dichotic digits test. Participants in the control group were also administered a handedness inventory. Statistical analyses revealed that there was no difference in the average order of report between the control group and test group. Degree of handedness did not correlate with the order of report in children with normal CANS function in this sample. The results do not support in-depth hand preference analyses for clinical use when working with individuals with suspected CAPD. Limitations of this study included small sample size.
