Peer reviewedMcCune, Lorraine; Vihman, Marilyn M. – Journal of Speech, Language, and Hearing Research, 2001
This study used longitudinal productivity criteria to establish the phonetic skill of 20 children (followed from 9 to 16 months). The number of specific consonants produced consistently across the months predicted referential lexical use at 16 months. Prior use of at least two supraglottal consonants characterized the children achieving…

Dimitropoulos, A.; Feurer, I. D.; Butler, M. G.; Thompson, T. – American Journal on Mental Retardation, 2001
Analysis of questionnaires completed by parents of young children with either Prader-Willi syndrome (N=84), Down syndrome (N=56), or typically developing (N=86), found children with Prader-Willi exhibited more compulsions, skin-picking, and tantrums than did the other groups. Discriminant analysis identified two functions (developmental milestones…

Peer reviewedGruber, Frederic A. – Journal of Speech, Language, and Hearing Research, 1999
Probable ages of normalization were calculated for 24 children with speech delay, using Kaplan-Meier analysis. Formulas are provided that permit calculation of the likelihood that individual children will normalize by a given age. Analysis revealed two different paths to normalization with children following one of the paths likely to retain…

Richards, Ruth C.; And Others – 1986
The primary purpose of this study was to examine uneven early development in premature infants. A multiple regression analysis was performed in which birth weight, length of gestation, length of assisted feeding, and length of ventilation were used to predict the descrepancy between a child's Psychomotor and Mental Scale scores on the Bayley…

Peer reviewedKahn, James V. – Education and Training in Mental Retardation and Developmental Disabilities, 1996
This longitudinal study first administered the Uzgiris and Hunt scales (to predict learning of manual signs) to 34 children (mean age 5) with severe and profound mental retardation. Evaluation four years later indicated that achievement of stage five on the Uzgiris and Hunt scales was necessary for even minimal learning and use of manual signs.…
