In order to assess the potential role of imitation in early socialization, a study was conducted to investigate the content and development of children's imitative behavior in the home. Data consisted of incidents of immediate and deferred imitation collected over a 4- to 8-month period by mothers trained in observational recording. Subjects…

Toddlers (2 to 3 years) and preschool children (5 to 6 years) were repeatedly presented with a six-tone melody, then tested for their discrimination of a variety of pattern features, including the specific component frequencies, successive intervals, and general melodic contour. To manipulate the information-processing demands of the task, the…

Three studies investigating the emergence and early refinement of intelligent self-correction are described. Forty-one children ranging in age from 18 to 30 months served as subjects. Parents taught their children a hide-and-seek game in which the parent hid a toy in natural locations in the home while the child watched. After a 3- or 5-minute…

Children's ability to produce integrated sequences of discrete behaviors was examined as a function of age and task demands for several behavioral domains. Results are discussed in terms of possible age-related constraints on combinatorial skills that operate at a general, cross-domain level during toddlerhood. (RH)

Forty toddlers, 1 1/2 to 3 1/2 years of age, and 8 adults, searched for stickers that were hidden underneath two discretely different classes of objects embedded in arrays containing several classes. Study results suggest that the children appear to have been attempting to determine which kinds of choices were the wrong ones. (Author/RWB)

Discusses a longitudinal study of young children's acquisition of complex sentences for expressing their beliefs about causally related events, in the transition in language development from simple to complex syntax. While most of the children's statements expressed subjective meaning overall, the acquisition of syntactic connectives was…

A short-term longitudinal study of the peer-related social interactions of 111 developmentally delayed toddlers and preschool children was carried out. Results suggested the existence of unusually marked deficits in peer interactions. Possible contributing factors were discussed. (Author/RH)

Social interactions regarding moral and conventional transgressions were observed among two toddler groups. Each of 16 day care center classrooms, eight serving 13- to 27-month-olds and eight serving 18- to 40-month-olds, was observed for three 45-minute sessions. Implications of results concerned the developmental origins of distinctions between…

Social play emerged earlier than social pretend play with a similar structure; the incidence of social pretend play increased with age. Four strategies for integrating pretense into social play were isolated; among them, verbal recruitment and "join" were found to be more effective than imitation or nonverbal recruitment.

This study of the processes guiding children's gender-linked conduct focused on ages prior to the development of self-regulatory control through the exercise of self-evaluative reactions. The study sample consisted of 29 boys and 33 girls in Australia between 17 and 48 months old. Measures included: (1) a videotaped toy play session in which…

Children of 15-33 months of age were presented with tasks measuring 2 facets of self: as the object of knowledge and as the subject of experience. Relations between tasks are discussed in terms of changes from the processing of immediate and visible features to the processing of more enduring and nonvisible features of the self during the toddler…

This longitudinal study investigated development and individual differences in exploration and play during infancy and toddlerhood among 34 children. Found that measures of developmental level, such as pretend play level and meaningful sequence, showed a significant increase between age 19 months and 30 months. (MDM)

Compared parents and nonparents to examine differences in the use of gender stereotyping to classify children's toys, and differences according to children's ages. Findings for 206 toys suggest that while toys are gender stereotyped for all age groups, there is more flexibility in gender stereotyping of toys for infants and toddlers. (SLD)

Two experiments used the preferential looking task to assess early word comprehension in 12- to 24-month olds. Results indicated that when target stimuli were named, 12-month olds displayed an increase in target looking for typical--but not atypical--targets, whereas 18- and 24-month olds displayed increases for both. (Author/KB)

Three experiments examined the relation between language acquisition and other symbolic abilities in 18- and 26-month-olds. Found that 18-month-olds spontaneously interpreted gestures, like words, as names for object categories. At 26 months, they spontaneously interpreted words as names and novel gestures as names only when given additional…
