Who shall be called language disordered? Some reflections and one perspective.

Area of Science:

• Child language development
• Clinical linguistics
• Developmental psychology

Background:

• Accurate identification of language problems in children is crucial for timely intervention.
• Current identification methods may conflate assessment goals and rely on inferred knowledge rather than observable performance.
• Distinguishing between at-risk children and those with diagnosed language disorders is essential.

Purpose of the Study:

• To outline key principles for the effective identification of language problems in children.
• To differentiate identification from other assessment objectives.
• To advocate for performance-based and contextually-sensitive identification strategies.

Main Methods:

• Analysis of assessment principles for child language disorders.
• Emphasis on distinguishing identification goals from broader assessment aims.
• Proposal for using language performance data across multiple contexts.
• Recommendation for explicit, age-based comparison standards.

Main Results:

• Identification should prioritize observable language performance over inferred linguistic knowledge.
• Language performance assessment requires sampling in diverse, including challenging, contexts.
• Comparison standards should be based on chronological-age peers, not mental-age peers.
• Clear distinction is needed between children identified with language disorders and those identified as at-risk.

Conclusions:

• Effective identification of childhood language problems hinges on distinct goals, performance-based assessment, and appropriate comparison groups.
• Assessment must capture language performance in varied situations to accurately identify disorders.
• Future research should focus on refining performance-based measures and contextual sampling for language identification.
