Effects of linguistic structure on children's ability to isolate initial consonants.

In 4 experiments, preschoolers and kindergartners were asked to pronounce the initial consonants of spoken words. Children performed better on short words, such as bay, than on long words, such as bonus. Words with initial consonant clusters, such as brow, were more difficult for the children than words without initial consonant clusters, such as bar. A consonant cluster at the end of the word did not harm performance. Children did relatively well on words like suppose, for which the word's 1st syllable, /s/, constitutes a correct answer on the initial consonant isolation task. Children did more poorly on words like satin, for which this was not the case. Thus, the linguistic structure of a word affects children's ability to isolate the initial consonant. Implications for the design of phonemic awareness instruction are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
