The study suggests that developing greater facility in linguistic skills may well produce greater cognitive differentiation and enhance the process of objectification. (Author)

First and second graders' understanding of transitivity for each of the relations "larger than,""smaller than,""longer than," and "shorter than" was investigated. Results showed that on only two of the eight comparisons did the order of presentation of the premises make a significant difference in students'…

Study 1 explored associations between multiple measures of language and symbolic gesture development across ages 3 and 4; Study 2 measured more finely which aspects of language relate to the symbolic representation of actions with objects, and explored associations between symbolic gesture and general intellectual ability. Results showed…

Examined hypothesis that experiences unique to schooling account for improved performance on invalid conditional syllogisms with age. Found small negative effect from out-of-school experiences and considerable positive effect of schooling; hence, unlike other cognitive tasks in which schooling operates in same direction as out-of-school…

Examined 4-, 6- and 8-year-old children's recency and frequency judgments, using drawings of common objects. Found accuracy of recency and frequency judgments improved between 4 and 6 years of age. Found no evidence that children in any age-group based their recency judgments on trace-strength information in episodic recall; found some evidence…

Twenty-four children in kindergarten through fourth grade were interviewed and asked to share a pancake fairly among three dolls. The context was chosen to allow children to use out-of-school intuition and understanding if preferred. Four levels of development were identified leading to the understanding of fair fractions as those where each part…

Examined the impact of maternal depression and adversity on mother-infant face-to-face interactions at 2 months, and on subsequent infant cognitive development and attachment. Disturbances in early mother-infant interactions were found to be predictive of poorer infant cognitive outcomes at 18 months. (MDM)

Discusses metacognitive and associative models of children's strategy discovery and use. Contends that models based on only one type of mechanism cannot entirely account for observed variability and constraint revealed by microgenetic studies of children's strategy change. Proposes a new model of children's strategy development in which…

Reviews research on children's and adults' beliefs about fantasy and their tendency to engage in "magical thinking." Suggests that children are not fundamentally different from adults in their ability to distinguish fantasy from reality. Both entertain fantastical beliefs and engage in magical thinking. Offers suggestions regarding age…

Responds to some of the specific criticisms of commentators, focusing on highlighting and exploring the themes of the role of culture, how adults characterize children, the meaning of the word "real," the importance of looking at adult literature, the role of process and content, placing a value on magical thinking, and similarities and…

Compares the many-perspectives account of lexical acquisition--which proposes that children learn to take alternative perspectives along with the words they acquire--to the one-perspective account--which proposes that children are at first able to use only one term to talk about an object or event. Provides evidence from a variety of sources that…

Discusses various components of adult cognitive development research, such as post-formal thinking and wisdom, with particular reference to the changing nature of careers. Offers 19 propositions concerning the thought processes characterizing effective management of career by individuals and discusses implications of the propositions for career…

The Interactive Learning Model illustrates how we process information (cognition), perform learning tasks (conation), and develop a self when performing difficult learning tasks (affectation). Individuals approach learning tasks with varying degrees of sequence, precision, technical reasoning, and confluence. These ingredients are embedded in the…

Examined infants' use of configural and physical knowledge in segregating three-dimensional adjacent displays. Found that infants do use configural knowledge: they expect similar parts to belong to same unit and dissimilar parts to belong to distinct units. Also found that physical knowledge, such as impenetrability and support, influences their…

Reed believes the proper study of psychology is not mind or stimulus-response phenomena but ways animals (including humans) encounter the world. In this view, animals are seen in environmental and evolutionary contexts; a fundamental concept is not mind or behavior but affordance or what environments offer animals; and new topics, such as…
