Stuttering and language ability in children: questioning the connection.

Area of Science:

• Speech and Language Pathology
• Child Development
• Linguistics

Background:

• The traditional view posits a connection between stuttering and language deficits in children.
• This perspective suggests language impairments may cause stuttering or hinder its development.

Purpose of the Study:

• To critically evaluate the evidence for a stuttering-language connection in children.
• To examine claims regarding language deficits in children who stutter (CWS) and their role in stuttering onset and persistence.

Main Methods:

• Systematic review of studies on syntactic, morphologic, and lexical development in CWS.
• Analysis of research investigating the association between language deficits and stuttering onset, persistence, and development.

Main Results:

• Children who stutter (CWS) exhibit a full spectrum of language abilities, similar to children who do not stutter (CWNS).
• No evidence supports language deficits as a cause or factor in the persistence of stuttering.
• Stuttering demonstrates minimal to no adverse impact on language development over time.

Conclusions:

• The proposed link between stuttering and language ability in children is not substantiated.
• An alternative model suggests that stuttering arises from motor control difficulties in speech production, not language deficits.
