Speech Intervention Outcomes Associated With Word Lexicality and Intervention Intensity.

ABSTRACT: Purpose This study examined how lexical representations and intervention intensity affect phonological acquisition and generalization in children with speech sound disorders. Method Using a single-subject multiple baseline design, 24 children with speech sound disorders (3;6 to 6;10 [years;months]) were split into 3 word lexicality types targeting word-initial complex singleton phonemes: /ɹ l ʧ θ/. Specifically, academic vocabulary words, nonwords (NWs), and high-frequency (HF) words were contrasted. Intervention intensity was examined by comparing the performance of 12 children who completed eleven 50-min sessions (4 children/word type) to the performance of 12 who completed 19 sessions (4 children/word type). Children's production accuracy of their treated phonemes and overall percent co
