When children with Down's syndrome and normally developing children of comparable mental age were compared in their ability to find things they saw in a mirror, it was found that the ability of children with Down's syndrome paralleled that of normally developing children, but that motivational, attentional, and exploratory differences may exist.…

Child positive affect and task orientation in response to cognitively demanding puzzle tasks were assessed at two time points separated by 12 months in children with mild mental retardation and mental age and chronological age matched controls (ages 1-5 years). Results suggested correlates of motivation were similar for children with mild mental…

To investigate the development of function concepts and their relation to mathematical and logical abilities typically acquired during the age period of five to seven years, children were tested on nonnumerical function tasks, numerical tasks, and aspects of logical reasoning. (PCB)

This two-part study began with a replication, statistical validation, and extension of the Karmiloff-Smith and Inhelder study of children's construction of theories about balance. The 128 subjects (ages 4 to 6) were videotaped as they tried to balance blocks on a fulcrum. A scale was developed to assess the degree to which the child's performance…

Describes five studies in which the learning and transfer abilities of two- and four-year-old children were examined on a task that required them to combine two separately learned solutions to reach a goal. (HOD)

Investigates the belief that caregivers' sensitive and contingent behavior is closely related to children's perceived control by analyzing the interactions between mothers and their 3 1/2- to 4 1/2-year-old children during a problem-solving task. (HOD)

Investigates the impact of early maternal employment--direct (mother-child) and indirect (father-child) effects--in families with firstborn 20-month-olds. Shows maternal employment is not related to toddler outcomes (security of attachment or problem-solving behavior). (HOD)

This paper explores the thesis that advances in computer applications and artificial intelligence have important implications for the study of development and learning in psychology. Current approaches to the use of computers as devices for problem solving, reasoning, and thinking--i.e., expert systems and intelligent tutoring systems--are…

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 book offers a holistic examination of well-being across the life course by experts in psychology, sociology, child development, and medicine, and describes foundational strengths for well-being from infancy through adulthood. The chapters are: (1) "A Brief History of the Study of Well-Being in Children and Adults" (Kristin A. Moore…
