Behavior analysts have spent relatively little time in designing interventions to enhance motor development in typically developing infants and children. This study examines the effect of a motor training package consisting of opportunity to respond and practice (standing the infant and letting her hold the fingers of the experimenter),…

Evaluation of 54 mentally retarded pupils, aged 10 to 13, in 1979 and comparison with six samples of mentally normal pupils collected during the last two decades confirm that prevalence of additional problems among mentally retarded pupils is greater as compared to mentally normal pupils with respect to nine variables. (NEC)

This pilot study used a task-analyzed performance base curriculum as an intervention on the gross motor development of 24 children aged three to six, 15 in a treatment group, 9 in a control group. Pre- and post-training data on gross motor development (relating to 10 motor skills) were collected using the Ohio State University Scale of Intra Gross…

This paper explores the issue of how, when, and where to teach keyboarding at the elementary school level through a review of the keyboarding literature and descriptions of three studies conducted with fifth grade students in the laboratory school at the University of Wyoming. The literature review briefly summarizes findings on the following…

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)

The development of 10 preschool children who attended the Southeast Kansas Demonstration Child Development Center was compared with the development of 10 preschool children who did not attend a child care center to ascertain the value of the center's program. Both groups were tested with the Denver Developmental Screening Test at the beginning and…

The authors' objective in this article was to explore the accuracy of mothers' estimates concerning their children's developmental functioning, especially with respect to vocabulary and gross motor development, by comparing the results of diagnostic tests administered to both the children and their mothers. The authors studied 55 children with…

A program at the Model Preschool Center for Handicapped Children at the University of Washington's College of Education enrolled 11 children with Down syndrome, 18-36 months of age. The program sought to accelerate and maintain the motor and cognitive skills of the children; to encourage parent involvement; to provide training to students,…

The patterns of adaptive behavior in gifted and nongifted children (n=296, ages 2-16) were compared using the Vineland Adaptive Behavior Scale. Results indicated a significant difference between gifted and nongifted groups in communication, social skills, and daily living skills, but not in motor skill development. (Author/JDD)

Examined children's developmental trajectories in five domains. Children were assigned to same- or mixed-age child care groups and assessed at 6-month intervals between approximately 32 and 49 months. Children in the two groups differed in their trajectories for communication, cognitive, and motor development but showed similar trajectories for…

Lip and jaw movements were studied longitudinally in 19-month-old children as they acquired the voicing contrast for /p/ and /b/. A movement tracking system obtained lip and jaw kinematics as participants produced the target utterances /papa/ and /baba/. Laryngeal adjustments were also tracked through acoustically recorded voice onset time (VOT)…

This descriptive report covers the first phase of a 20-year longitudinal study of black children adopted under 3 years of age by black couples, white couples, and single persons. The sample of three groups of approximately equal size was selected from the adoptive placements of two private child welfare agencies between June 1970 and June 1972.…

A study comparing family and group day care was conducted. Data were collected over a two-year period on 12 children in a Greensboro, N. C., family day care program and 10 children in the UNC-G Demonstration Center for Infant-Toddler Care, a group day care center. Results, which disproved many assumptions cited as advantages of family day care,…

This study, part of a naturalistic longitudinal study of infants being reared in a variety of family life styles, attempted to establish the extent to which differing parenting patterns affected early developmental outcomes. Subjects were 200 infants: 50 of single mothers who headed their family units, 50 of mothers in communal living groups, and…

Deaf children of Deaf parents perform better academically (Ritter-Brinton & Stewart, 1992), linguistically (Courtin, 2000; M. Harris, 2001; Vaccari & Marschark, 1997), and socially (Hadadian & Rose, 1991; M. Harris, 2001) than Deaf children of hearing parents. Twenty-nine Deaf children in residential schools were assessed to determine if a…
