A study compared a naturalistic versus an analog teaching model, with speech sounds equated within and across conditions for five children (ages 4-7) with autism. Both methods increased correct production of target sound under some conditions; functional use of the target sounds in conversation occurred only with the naturalistic approach.…

Twenty preschoolers with impairments in both morphosyntax and phonology were assigned to an intervention of two 12-week blocks beginning with either a block of phonology first (n=10) or a block of morphosyntax first (n=10). Both interventions were effective. The morphosyntax first sequence led to slightly better overall morphosyntactic…

A study of 36 children (ages 3-5) compared traditional and phonological treatment of 36 children with multiple articulation disorders. Results found that the response of children in the traditional therapy group was substantially inferior; the children in the phonological therapy group showed more improvement with fewer therapy sessions.

The lexical variables of word frequency and neighborhood density were hypothesized to facilitate sound change to varying degrees. Twelve children with functional phonological delays participated in an alternating-treatments experiment to promote sound change. Results indicated word frequency was most facilitative in sound change, whereas dense…

This purpose of this randomized group experiment was (a) to test the post-treatment (i.e., immediately after treatment) and follow-up (i.e., 8 months after the end of treatment) efficacy of a treatment designed to facilitate both sentence length and speech intelligibility (i.e., broad target recast), and (b) to explore whether pretreatment speech…
