The contrastive/noncontrastive model developed by Seymour and Seymour (1977) can be applied to the development of a dialect-sensitive phonological assessment that uses a single scoring and test format, regardless of a child's dialect. Through extensive field research, stimulus items were found that respect the phonotactics of African American English (AAE) (i.e., no targets are final consonants or final consonant clusters), yet are sufficiently demanding to show development in the age range from 4 to 9 years. Consonant clusters of varying levels of phonological difficulty are shown to discriminate between typically developing and phonologically impaired children of different dialect groups, Mainstream American English (MAE) and non-MAE. Implications for further diagnosis and remediation are presented.KEYWORDS: Contrastive and noncontrastive substitution patterns, type I, II, and III errors, consonant clusters Learning Outcomes: As a result of this activity, the participant will be able to identify (1) how the contrastivenoncontrastive model of assessment was applied in the development of the proposed dialect-sensitive phonology assessment, and (2) several key features of the proposed phonology assessment items.
PHONOLOGY DOMAINThe contrastive/noncontrastive model 1 described in Seymour 2 was applied in the development of a dialect-sensitive phonology assessment. As with other domains of language, contrastive refers to phonological features that differ (contrast) between African American English (AAE) and Mainstream American English (MAE). The most common of these features in AAE are absent elements of consonant clusters and the absence of a word final consonant. 3,4 These contrastive features have Evaluating Language Variation: Distinguishing Dialect and
