Three longitudinal studies examined means-ends behavior of 6- to 8-month olds. Found that intentional means-end behavior increased between 6 and 7 months, with 7-month olds' performance influenced by the presence of a toy on the cloth. Performance was the same when cloth was attached to or separate from the toy. By 8 months, infants adjusted…

Two studies examined preschool teacher and child interactions regarding personal, moral, and socioconventional issues in the classroom and the development of personal concepts. Findings suggested that in both judgments and social interactions, teachers and children identified a personal domain in which children can and should make choices about…

Investigates the characteristics of the intrafamily environment that change the intellectual environment of the children and interact with the factor of birth order. Concludes that the effect of birth order is linked: (1) with the gender configuration of sibling relationships; and (2) with various cognitive and personal characteristics of the…

Surveyed 7-year-olds' ideas about the Earth in space, focusing on their ideas about shape and their ability to represent and describe land masses or other surface features, Earth's size relative to the sun and moon, and its nature as a planet. Found that focusing on the Earth's shape and gravity alone has underestimated youngsters' learning…

Two studies examined preschool children's beliefs about maternal intention as a mechanism for trait inheritance. Study 1 indicated that preschoolers believe that maternal intention plays a role in inheritance of physical traits. Study 2 suggested that children see some properties as outside maternal control, and that maternal intention operates…

Compared the interaction of depressed and nondepressed mothers and their infants with joint attention during mother-infant play. Found that although maternal vocal attention was generally higher for male infants than for female infants, depressed mothers gave more vocal attention to female infants. Found no correlation between mothers' vocal…

Maintains that although Kohlberg emphasized the importance of perspective taking in moral reasoning, his view of developmental stages is inconsistent with this position. Argues that a modification of Kohlberg's conception of stages drawing on Piagetian theory would result in a view of moral reasoning as a process of coordinating all perspectives…

Examined the relationship between language and cognitive development and emotional-behavioral problems (measured concurrently and at a 5- and 17-month follow-up) in 680 nonreferred 4-year-olds from financially-disadvantaged families. Found that language delays were significantly related to emotional-behavioral problems. When cognitive differences…

Examined 5- to 12-year-olds' emerging understanding of the origins of species in two studies. Demonstrated systematic developmental pattern in children's explanations for biological origins. Found age-related shifts from mixed creationist and spontaneous generationist explanations, to exclusive creationism, and finally to evolutionist or…

Examined word retrieval in 14- to 24-month-olds. Found that children with limited productive vocabularies were less likely to produce labels of hidden objects than children with larger vocabularies, even though all could name them and did well when asked to find them. Pictorial cues facilitated word retrieval. Naming errors peaked among children…

Examined degree to which analytic and holistic modes of processing play a role in children's and adults' categorization of faces. Found a developmental trend from analytic to holistic processing and an effect of face inversion with increasing age. Seven-year-olds processed faces comparably to nonfacial visual stimuli, whereas a growing proportion…

Explores relations among depth or timing of poverty, mother's marital history, and quality of the home environment for children ages 6 to 9 years. Results, based on a national longitudinal survey, indicate that the quality of the home environment is substantially lower for poor children than for children who are not poor. (RJM)

Compares drawings of English children with mild learning difficulties (M.L.D.) with those of children of the same chronological age and of the same mental age. Reports that drawings by M.L.D. children are similar to those of children at the same mental age. Suggests that M.L.D. children follow a normal rather than deviant developmental pattern.…

Investigates children's development of causal explanations of success and failure. Compares two measures of causal attribution to show that the use of unipolar scales best depicts differences in causal factors used by children. Explores two hypotheses about the impact of normative context on the development of causal differentiation. (DSK)

Explores the nature of images created by Paleolithic artists and autistic artists in regard to drawing techniques and image function. Explains the commonalities based on a discussion of the role of the early vision process and the construction of meaning. Notes the importance of this research for understanding autistic artists.
