Nineteen children with motor problems were selected from a sample of 331 third-graders taking Gubbay's Test of Motor Proficiency and a battery of achievement tests. Teachers' ratings of clumsiness had low correlation with criteria of clumsiness derived from performance tests. Frequency of learning disabilities was high. (Author/LMO)

Reports an 18-month longitudinal study of sign language acquisition in very young children of deaf parents. Results indicate that some revision of views on cognitive prerequisites for language is necessary. Implications for nonspeaking populations and for developmental theory are discussed. Reviews briefly sign language training programs for…

Studied across a 16-month period, young children of deaf parents showed accelerated early language development, on the average producing their first recognizable sign at 8.5 months, their tenth sign at 13.2 months, and their first sign combination at 17.0 months. Findings are inconsistent with previously reported patterns of synchrony between…

This paper presents the results of a comparative analysis between full term typical infants and those born micropremature in the developmental construct of mastery motivation. The sample consisted of 10 micropremature infants with developmental levels within the normal limits and 10 full term 9- to 12-month-olds (adjusted for prematurity) matched…

Developmental data on 612 home reared, Down's Syndrome children, from birth through 16 years of age, were collected over 20 years from an outpatient clinic for mentally retarded children and were statistically analyzed to ascertain normative times of motor, language and intellectual developmental behaviors.
