Word frequency and neighborhood density are properties of lexical
organization that differentially influence spoken-word recognition.
This study examined whether these same properties also affect spoken-word
production, particularly as related to children with functional phonological
delays. The hypothesis was that differential generalization would
be associated with a word's frequency and its neighborhood density
when manipulated as input in phonological treatment. Using a multiple
baseline across subjects design, 8 children (aged 3;10 to 5;4) were
randomly enrolled in 1 of 4 experimental conditions targeting errored
sounds in high-frequency, low-frequency, high-density, or low-density
words. Dependent measures were generalization of treated sounds and
untreated sounds within and across manner classes as measured during
and following treatment. Results supported a hierarchy of phonological
generalization by experimental condition. The clinical implications
lie in planning for generalization through the input presented in
treatment. Theoretically, the results demonstrate that lexical organization
of words in the mental lexicon interacts with phonological structure
in learning.
