Reports a method of clinically inducing a phonemic split in a misarticulating child. Three stages were observed in the acquisition of this split: (1) complementary distribution (allophones of the same phoneme); (2) position-specific free variation (intermediate to the phonemic split); and (3) phonemic distribution for some morphemes (phonemic…

Describes a study which examined the phoneme acquisition process by monitoring children's progress toward the goal of being able to use a target behavior in multiple situations after treatment has been withdrawn. This was done to determine whether progress continues if treatment is withdrawn before the end goal is reached. (SED)

Analyzes the nature of Down's syndrome children's articulation problems, including the phonetic inventory of each subject; a comparison of target consonant phonemes and the subjects' renditions of these phonemes; and a characterization of the subjects' errors in terms of phonological processes. Finally, discusses three major findings emerging from…

Comparison of normal-speaking (N=20) and misarticulating (N=20) four- to six-year-olds and adults (N=16) revealed that adults were significantly more accurate in detecting mispronunciations than either group of children, while performance between the two groups of children was similar. Words that children found most difficult were also those on…
