Although not the focus of her article, phonological development in young children with speech sound disorders of various types is highly germane to Stoel-Gammon's discussion (this issue) for at least two primary reasons. Most obvious is that typical processes and milestones of phonological development are the standards and benchmarks against which…

Discussion of speech sampling in the assessment of children with phonological disorders focuses on the use of nonlinear phonological analysis, a method whereby multiple aspects or levels of a child's phonological system are examined. Principles and suggestions offer general guidance for adequate sample elicitation. (Contains references.)…

This tutorial in nonlinear phonology introduces the basic concepts and assumptions of this new theoretical approach and then demonstrates clinical applications of the theory for assessment and intervention. Data from a child with a severe phonological disorder are used to illustrate aspects of nonlinear theory. (Author/DB)
