Eighty at-risk infants were administered the Mental and Motor Scales of the Bayley Scales of Infant Development at 6 and 12 months of age. Test-retest reliability scores of .71 on the Mental Scale and .69 on the Motor Scale were obtained. (Author/JDD)

Subjects with autism (n=36) were assigned a simple "reach, grasp, and place" task. Comparison with nonautistic children who had mental retardation and younger normally developing children found that the autistic subjects had problems in executing goal-directed motor acts even in very simple situations, suggesting an independent and marked…

Tested infants in their second year with a box task to determine whether they would show a hand preference in solutions involving complete differentiation of roles for the two hands. (HOD)

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…

A method for empirical classification of autistic and autisticlike children, based on behavior observations of 35 males and 11 females (ages 4-28 years) was examined. Factor and cluster analysis indicated four subtypes, characterized by perseverative thinking and play, motor disturbances, schizotypal/schizoid features, and anxiety and negativism.…

Evaluation of the Kent Scoring Adaptation, which determines developmental ages in several domains based on an infant's performance on the Bayley Scales of Infant Development, with 27 at-risk infants supported the concurrent validity of the cognitive, language, and, to a degree, social domains of the Kent procedure but not the fine and gross motor…

Reports on a longitudinal study of cognitive and motor development among infants born to adolescent and adult mothers when race, parity, socioeconomic status and prenatal care were controlled and home environment evaluated. (HOD)

Two studies on cognitive performance in mentally retarded children are reported. In the first study, the Bayley Scales of Infant Development were administered to 56 mentally retarded children, aged 2 to 6, to determine the possibility of discerning subsets of items that form a developmental pattern of interrelated subscales, using the SCAMMO scale…

This handbook is a guide and reference document for those researching the child data files of the 1986-1990 National Longitudinal Survey of Youth, sponsored by the Bureau of Labor Statistics. It describes the child data collection procedures, the nature of the child sample, the child data files available, and the specifics of the child assessments…

Down Syndrome children (N=229), aged 1-83 months, from Australia, Canada, and Germany were tested using the Bayley Scales of Infant Development. Test performances on the Bayley's Mental and Motor scales were not dissimilar, leading to the conclusion that young Down Syndrome children from different countries with relatively comparable standards of…

An intensive early intervention program was evaluated by assessing gains made by 44 special needs children (age 2) in cognition, gross motor, fine motor, receptive language, and expressive language domains. Comparison of actual to predicted posttest scores did not reveal significant gains in any domains. In cognition, gross motor, and fine motor…

The ten chapters in this volume address issues of concern to those who work with or conduct research with young children and those who plan programs or prepare others for teaching or caregiving. Included are "The Development of Bilingual and Bicultural Competence in Young Children," by Muriel Saville-Troike; "Development of…

The National Research Council formed a Committee on Educational Interventions for Children with Autism and charged the committee with integrating the scientific, theoretical, and policy literature and creating a framework for evaluating the scientific evidence concerning the effects and features of educational interventions for young children with…
