Abstract: Objective: The association between deficits in verbal processing skills and disruptive psychopathology remains one of the most frequently replicated findings in all of child psychiatry. This study uses a dichotic consonant-vowel listening test to examine the potential neural basis for this association. Method: A series of 87 young boys recruited from a sample at risk for disruptive disorders received standardized psychiatric, neuropsychological, and language skills assessments. Approximately 1 year later, these boys received a reassessment of their psychiatric status and a test that assesses the neural basis of language-processing ability, a dichotic consonant-vowel listening test. Results: Disruptive psychopathology predicted reduced right ear accuracy for dichotic syllables, indicative of a deficit in left hemisphere processing ability. Deficits in reading and language ability also correlated with right ear accuracy for dichotic syllables. Conclusions: Boys with disruptive behavior disorders, relative to at-risk but nondisruptive boys, exhibit a deficit in verbal processing abilities on dichotic listening tasks. This deficit in verbal processing ability is also manifested as low scores on standardized tests of reading achievement and language comprehension.
