In contrast with Leonard (in this clinical forum), I believe understanding the cause of specific-language impairment is an important issue in the study of this condition. A model of language impairment that contains two primary sources of causation is proposed and then applied to the problem of specific-language impairment. Further, Leonard is interpreted as proposing that specific-language impairment is caused by the same factors as those that cause normal variation in language function. In light of this, a method of testing this hypothesis is provided.
