Describes an experiment to see whether the words "front" and "back" introduce the concept of "front-back" or whether the concept preceded the words. Results show that (1) a complex disjunctive concept of "front-back" orientation precedes any knowledge of the words; (2) linguistically, "back" is comprehended before "front"; and (3) children at an…

Four-year-olds succeeded in making comparisons between sets of objects when comparison questions called for comparing set with set or subset with subset. However, when comparison questions called for comparing set with subset, the children failed to complete such tasks successfully. (Author/DB)

Summarizes research done in the 1950s, early 1960s, and mid-1970s about how children and adolescents think about economic related ideas. Economic reasoning develops in a stage-like manner similar to Piagetian stages of cognitive development, becoming more abstract, other-directed, and flexible with increasing age. (RM)

Reviews recent progress in modeling human cognition, in particular the use of computers in generating models. Topics covered include the information processing approach to cognition, problem solving, semantic memory, pattern induction, and learning and cognitive development. A 164-item reference list is attached. (JL)

Examines the issue of object sorting in early infancy. Forty-eight infants at 6, 9, and 12 months were presented with eight sets of small, manipulable objects. At six months, selective manipulation was absent; at nine months, 94 percent of the infants sequentially touched similar objects and at 12 months 100 percent did so. (Author/DB)

Children and adolescents from four social classes were asked to describe rich and poor people and to indicate how the rich and the poor are different from and similar to each other. Responses were classified into three categories of person description: peripheral (possessions, appearances, and behavior), central (traits and thoughts), and…

The fact that the autistic children were so impaired in language even with fairly good sensorimotor skills suggests that these skills, particularly object permanence, play a minor role in their language acquisition. (Author)

This study examines the effectiveness exercises based on the cognitive conflict, existing within the child, between two representational systems related to temperature: the qualitative-verbal one and the quantitative-numerical one as these relate to the advancement of children's understanding of the concept of temperature. (Author/DS)

Described is the interview-about-instances method used to gain insight into children's and adults' views of the world and the meanings people have for the words they use in explaining their views. Physics teachers can utilize this technique to become aware of the various concept understandings pupils bring to physics classrooms. (DS)

Provides data incongruent with Piaget's idea of a concrete operational stage. Shows no clear-cut termination of preconceptual thinking and no simultaneous conceptual development in the three content areas (number, space, and time). (Author/RL)

Five steps described by Dienes by which mathematics is learned are illustrated through the use of the topic of direct proportion. (MP)

Children's use of causal and logical connectives was examined before and after treatments based on advance organizers with social studies lessons. In samples of 120 children from age-levels 6 and 10 years a diminution in the use of syncretic reasoning and understanding followed the experimental treatment. (Editor)

Focuses on three main issues emerging from studies of conceptual development: (1) young children's naive theories of the world; (2) how innate constraints in conceptual development work; and (3) how innate and sociocultural constraints are integrated. Maintains that early development of core domains of thought (naive psychology, physics, and…

Two studies of development of spatial representation with two dimensions found that children as young as five years use the same two independent dimensions in fine-grained spatial coding of location in a circle as adults use--radius and angle. The adult pattern, where angle as well as radius is coded hierarchically, emerges by nine years. (HTH)

Examined three- to five-year-old children's understanding of pretense and deception in folktales in which a villain deceived his victim by pretending to be someone else. Found that the three-year-olds were able to follow the pretense but were not able to grasp the false belief integral to the deception. (MOK)
