Investigates the developmental sequence of learning to transform objects into agents and recipients of action in early symbolic play. Each of 48 children (from 14 to 25 months old) demonstrated initiative pretending after an adult modeled agent and recipient substitutions in pretending to talk on the telephone. (Author/CB)

Describes various types of play typical of infants and toddlers. Includes discussion of the developmental benefits of object play, social play, motor play, and imitation. Focuses on the concept of causality, toddler-invented games, repeated movement to gain mastery, and the beginnings of dramatic play. (KB)

The study sought to examine developmental processes of substitution in the pretend play of Down's syndrome children and to clarify the onset mechanism of subskills in decontextualization, which refers to the progress from imitation to substitution and then to invention. Eighteen Japanese children, aged 29-55 months, with Down's syndrome were given…

Presents a longitudinal study of six children which investigates the relationship between language development and the development of nonverbal representation. Concludes that the results suggest an interrelational hypothesis and proposes an interpretation in terms of reciprocal interaction between the two parameters. (Author/MES)

Three mothers of handicapped children were taught to imitate their child's behavior; subsequently the number of mands displayed by the mothers during play sessions were measured. Results showed increases in the percentage of sample intervals during which mothers imitated their children and showed that, as imitations increased, mands decreased.…

This study examined the functions of structured modeling and mother-child play settings upon the development of pretend actions in young Down Syndrome children. Subjects were 30 pairs of Japanese children, with a developmental age range of 12-35 months, and their mothers. The children were individually administered five phases of premodeling,…

Reviews research on the early development of symbolic play. Suggests that symbolic play begins to emerge near the beginning of the child's second year and continues to play an important role in his or her development throughout the preschool years. Proposes basic techniques caregivers can use to facilitate and promote the development of symbolic…

Tested a proposed developmental pathway for toddlers' mastery of skills in generating non-ritualized forms of cooperative coordinated action with peers. Studied nonverbal imitative acts among U.S. toddlers and toddlers of the Seltaman people of Papua New Guinea. Found that ready imitation of one another emerged during the same developmental period…

The paper defines and discusses various social learning theories. Central to most theories of how an individual acquires socially acceptable behaviors are the processes of imitation, or observational learning, and identification, or modeling. The effectiveness of each process is noted. (SB)
