The Effects of Phonological and Morphological Training on Speech Perception Scores and Grammatical Judgments in Deaf and Hard-of-

Seventeen primary school deaf and hard-of-hearing children were given two types of training for 9weeks each. Phonological training involved practice of /s, z, t, d / in word final position in monomorphemic words. Morphological training involved learning and practicing the rules for forming third-person singular, present tense, past tense, and plurals. The words used in the two training types were different (monomorphe-mic or polymorphemic) but both involved word final /s, z, t, d/. Grammatical judgments were tested before and after training using short sentences that were read aloud by the child (or by the presenter if the childwas unable to read them). Perception was tested with 150 key words in sentences using the trained morphemes and phonemes in word final position. Grammatical judgments for sentences involving the trained morphemes improved significantly after each type of training
