The relationship between abnormal stereotyped behaviors and abnormal focused affections was examined in 20 children (ages 7-13) with developmental disabilities. Results include all children with abnormal focused affections exhibited stereotypes; abnormal focused affects could be studied reliably in this population through several methodologies;…

Behavior state and environmental data were collected over a 5-hour period for approximately 66 students with profound disabilities from 21 educational settings. Results showed a strong relation between different state profiles and measures of development and consistency of state patterns across chronological age levels. Results are discussed in…

Tests three previously untested hypotheses central to the theory of Brazelton and colleagues about the sequential structure of mother-infant face-to-face interaction. Results show that with some revision the hypotheses describe the structure of mother-infant face-to-face interaction from three to nine months of age. (Author/RH)

Children's ability to produce integrated sequences of discrete behaviors was examined as a function of age and task demands for several behavioral domains. Results are discussed in terms of possible age-related constraints on combinatorial skills that operate at a general, cross-domain level during toddlerhood. (RH)

Reports two experiments in which eight patients with organic memory disorders exhibited a pattern of search behavior that resembled mnemonmic precedence--the ability to retrieve an object at an initial location, but not at a new location. (HOD)

Recent experimental research is synthesized to identify distinctive biobehavioral characteristics of Down's Syndrome persons across their lifespan. It is argued that educational and other intervention programs have not demonstrated strong gains having significant durability or generalization. Recommended is an interactionist function-structure…

Data concerning maladaptive behavior obtained on a sample of persons (n=8255) with mild to profound mental retardation and aged from birth to 98 years were factor analyzed resulting in identification of 2 principal factors for children, 3 for adolescents and young adults, and three and 4 for middle and older adults, with level of retardation also…

Examines the ability of six- and eight-year-old children to hide and recover 20 marbles in a large room containing 100 possible sites. Shows that children tend to concentrate activities in sections of the room and are sensitive to clusters of proximal sites. (HOD)

Studies examining the influence of peer pressure on the drinking behaviors of college students have focused primarily on undergraduates. Very little is known about the drinking patterns of graduate students. To compare drinking patterns of undergraduate and graduate students, 57 college freshmen, 20 sophomores, 24 juniors, 26 seniors, 46 graduate…

This investigation addresses problems of defining verbal imitation, and suggests solutions by analyzing verbal interactions between two children and their mothers. Children were between 18 and 35 months old, with a mean length of utterance between 1.4 and 4.2 morphemes. Analyses focus upon the uses these children made of maternal models; 10…

Rigidity, as it relates to aging, refers to motor/cognitive, personality/perceptual, and psychomotor functioning. To investigate the relationship of rigidity to intelligence and educational level in younger and older adults, and of rigidity to age and sex, 48 young adults (25 male, 23 female), with a mean age of 23, and 45 older adults (21 male,…

Examines verbal interactions of mothers and fathers with their school-age children (9 and 12 years of age) during structured sessions. Mothers, more than fathers, tend to use more problem-solving behaviors with their 9-year-olds than with their 12-year-olds and boys discriminate more than girls in their use of problem-solving behaviors with…

Decribes age trends in television viewing time and visual attention of children and adults videotaped in their homes for 10-day periods. Shows that the increase in visual attention to television during the preschool years is consistent with the theory that television program comprehensibility is a major determinant of attention in young children.…

Reviews and integrates several aspects of peer interaction in the infant/toddler period. Reveals convergence between age-related changes in social skills and similarly timed cognitive developments. (HOD)

Examines the hypothesis that biases in peer interpretations of social behavior may contribute to the stability of social acceptance and rejection in children. (HOD)
