Stuttering and Language Ability in Children: Questioning the Connection

Abstract

This article explains why it is reasonable to question the view that stuttering and language ability in children are linked-the so-called "stuttering-language connection." Studies that focused on syntactic, morphologic, and lexical development in children who stutter (CWS) are examined for evidence to support the following claims: (a) that CWS, as a group, are more likely to have disordered or weak language skills ("language deficits") than children who do not stutter (CWNS); (b) that language deficits play a causal role in the onset of stuttering; and (c) that stuttering, over time, restricts children's language development. Analysis of the evidence suggests that CWS, like CWNS, show the full range of language abilities (high, average, low); that language deficits are not associated with stuttering onset or persistence; and that stuttering has little or no impact on language development. A connection between stuttering and language ability was not supported. An alternative perspective is that CWS have a compromised motor control system that makes it difficult for them to move forward in speech and that the tie to language lies not in a deficient linguistic system but in difficulty expressing the intended meaning via a fully functional speech system.
