Purpose: The purpose of this study was to determine whether nonlinear phonology could be applied to assessment and treatment in a public school setting. It was hypothesized that the nonlinear phonology approach to target selection would result in more rapid improvement in specific treatment targets, more generalization to other structures or segments, and greater improvement in overall speech intelligibility than had occurred with previous treatment. Method: Nonlinear phonology postulates a hierarchical organization of the sound system such that a word is composed of progressively smaller units, each with its own representational tier/level (i.e., words, syllables, segments, features). Targets chosen using this approach are typically derived from varying levels of the hierarchy (e.g., syllable structures and segments) to promote systemwide change. A nonlinear phonology approach to target selection was implemented with 1 child, age 6, who exhibited a |
