Calling this a major contribution to the field of psycholinguistics, Professor Dennis Mol­fese notes that it “stands out as perhaps the major work in the area of phonological de­velopment in the last decade. It should be­come a major reference work and the proce­dures employed (both for data collection and, perhaps, more so for data analysis) could well set the tenor for the next decade.”

The eight essays by various contributors in this book review the literature on phonological development, emphasizing prob­lems relating to age, phonemes, and distinc­tive features. The methodology of data collection, storage, retrieval, presentation, and analysis is described. Data are presented descriptively by individual chapters for each of five age groups: 18, 24, 36, 48, and 72 months. Summary data are presented, using both descriptive and inferential statistics across the entire sample.

One hundred children, 20 at each age group, served as subjects. All language sam­ples were collected in spontaneous situa­tions. A total of 86,661 phonemes was en­tered for analysis. Two distinctive feature systems—the Irwin-Wong and the Chom­sky-Halle—were employed in all analyses. Data for both phonemes and distinctive fea­tures were presented in terms of distri­bution, acceptability of production, and na­ture of any replacement.
