Concrete Features of Vocabulary Development from Puberty through Adolescence.
Williamson, Leon E.
Using the counting features in previous mean length of utterance (MLU) studies, a study of the active vocabularies of adolescents looked at seven concrete features of the words 104 seventh grade and 100 eleventh grade subjects gave in response to 10 pictures. Each subject wrote five words for each of the pictures, which were analyzed for number of phonemes, syllables, prefixes, combining forms, and derivational suffixes. Each word was assigned a part of speech and a standard word frequency index value found in the American Heritage Word Frequency Book. The results indicated that the prefix variables were most consistent in indicating significant differences between the vocabularies of the two grade levels. After the second response for each of the pictures, phoneme count and the probability statistic for appearing in print distinguished between the vocabularies for these two groups. The third and fifth response differentiated the two vocabulary levels best with the third yielding significant differences for all the variables except for part of speech. The fifth response did not yield data that differentiated for the variables identified as part of speech and derivational suffixes. (HTH)
