We aimed to longitudinally examine how symbolic distancing affects preschool children's delay tolerance in a delay choice task. We presented children with choices between a smaller immediate reward and a larger delayed reward in conditions with either symbolic stimuli or edible rewards. Overall, symbolic distancing modulated children's delay…

Two non-verbal cognitive systems, an approximate number system (ANS) for extracting the numerosity of a set and a parallel individuation (PI) system for distinguishing between individual items, are hypothesized to be foundational to symbolic number and mathematics abilities. However, the exact role of each remains unclear and highly debated. Here…

The purpose of this study was to examine the features of the peer culture that a group of preschoolers created in their classroom in the province of Kahramanmaras, Turkey. An ethnographic approach was adopted in this study to obtain an in-depth understanding of children's peer interactions. The data were collected through variety of data…

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.…

Three studies were conducted to assess the abstraction processes involved in the development of the ability to associate numerals with sets of the appropriate size (numeration). Experiment 1 examined the sequence of the ability to discriminate relative numerical magnitude, numerical equivalence, Arabic numerals, absolute size of a set, and…

Purpose: The purpose of the present study was to examine the effectiveness of an instructional procedure called "aided language modeling" (ALM) on symbol comprehension and expression in 2 preschool children with autism who used few words functionally. ALM consists of engaging the child in interactive play activities and providing models of use of…

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;…

Observation indicated that children most frequently represent objects by performing actions appropriate to the represented objects. With increasing age, children represent objects without using functional actions and with objects bearing little physical similarity to the represented objects. (Author/DB)

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…

Describes a developmental study of semantic structures in children who are asked to determine the fitness of descriptive labels for line drawings representing a variety of perceptual stimuli. (Author/WY)
