phonological disorder
A speech sound disorder characterized by predictable, rule-based errors affecting sound patterns rather than motor production difficulties.
Full Definition
A phonological disorder involves systematic patterns of sound errors that affect a child's phonological system organization. Unlike articulation disorders, which stem from motor execution problems, phonological disorders reflect underlying difficulties with sound pattern rules and phonemic contrasts. Common patterns include final consonant deletion, cluster reduction, and stopping of fricatives. Treatment focuses on establishing phonological awareness and contrastive patterns rather than motor practice.
Usage
Usage note: Distinguish from articulation disorders, which involve motor production issues rather than phonological rule deficits.
