Kevin (4;7 Years) Is a Monolingual English-Speaking Boy

Kevin (4;7 years) is a monolingual English-speaking boy. He has velar fronting of /k, g/ across all word positions in singleton and consonant cluster contexts. In preparation for evaluating Kevin's progress on the short-term goal of eliminating velar fronting, you need to:

A) sample /k/ and /g/ in word-initial position in 20 non-treatment words, as any change in word-initial position should generalize to other word positions.
B) administer a standardized phonology assessment every fortnight.
C) compile an informal picture-naming task comprising 32 non-treatment words (four of /k/ and four of /g/ in word-initial, within word, and word-final positions, and four word-initial consonant clusters and four word-final consonant clusters) .
D) compile an informal picture-naming task comprising eight non-treatment words (one of /k/ and one of /g/ in word-initial, within word, and word-final positions, one word-initial consonant cluster and one word-final consonant cluster) .
