At the beginning of preschool (M = 46 months of age), 197 (94 boys) children were administered tasks that assessed a suite of nonsymbolic and symbolic quantitative competencies as well as their executive functions, verbal and nonverbal intelligence, preliteracy skills, and their parents' education level. The children's mathematics achievement was…

In 4 experiments 120 three-to four-year-old non readers were asked the identity of a symbolic representation as it appeared with different objects. Consistent with Bialystok (2000), many children judged the identity of written words to vary according to the object with which they appeared but few made such errors with recognizable pictures.…

In 3 studies, 2.5- and 3-year-olds transferred knowledge from an easy task that required appreciation of a symbolic relation to a more difficult task involving a symbolic relation that children their age typically do not appreciate. Results support the theory that young children use insight into one symbolic relation to understand other symbolic…

Discusses the emergence and early development of symbolic functioning in children engaged in nonverbal, expressive activities. Concludes that symbolic functioning must be considered in the affective as well as cognitive sphere of development. Implications for educational practice and questions for further research are presented. (DP)

Two experiments examined children's ability to understand and produce graphic symbols for social communication. Found that 2-year-olds did not effectively produce symbols or use an experimenter's symbols. Three- and 4-year-olds improved their symbols after use in social communication and performed above chance with the experimenter's symbol;…

Two studies examined understanding of notational representation among 3- to 5-year-olds. Children solved problems when shown cards with a picture or word indicating identity or a quantity indicator. In the easier condition, children had difficulty solving the problems as a function of their familiarity with the notation, suggesting weaknesses in…

Two studies examined the progress in normally developing preschoolers' ability to produce actions with imagined objects (pantomimes). Found that young children not only had difficulty producing imaginary object representations in contrast to normal adults, they also had difficulty comprehending imaginary object representations and were better at…

Discusses ideas from Vygotsky, Leont'ev and Bakhtin to show how fantasy play acts as its own zone of proximal development that contributes to the development of symbolic mediation, the appropriation of social roles and symbols, and the preschool child's preparation for elementary school. (JPB)

This paper examines the interrelationship between children's acquisition and use of symbols and the development of imaginative play. The paper focuses on the use of pretend play as an expression of the child's capacity for symbolic functioning and as an index of intellectual development. The first section of the paper reviews developmental changes…

An experiment demonstrating that children in Piaget's preoperational stage, who generally still cannot give conceptually correct answers to questions about rate and time, evidence an ability to imitate a given rate-time relationship demonstrated by the experimenter. (ST)

Tested understanding of correspondence on the part of 2.5- to 3.5-year olds who watched a toy hidden in a model and tried to find an analogous toy in a room. Retrieval scores increased with increasing model-room similarity; were higher for older than younger children; and were affected by object and size similarity. (BC)

Representational competence refers to the individual's capability to respond appropriately to external representations. For example, a child engaged in a grouping task may collect together all like objects even if the group contains varying representations of the object, including (1) the object itself, (2) a three-dimensional likeness of the…
