This paper focuses on possible relations between early peer skills and developing cognitive abilities. One promising area for discovering relations between cognitive development and peer interaction appears to be related to the young child's developing ability to differentiate self from other, that is, decentration. Decentration is typically…

Observations suggest that 12-month-old children show little evidence of possession rules, while 18- and 24-month-olds are still coming to differentiate purely personal possession rules from shared possession rules that take into account the other child's status or rights as a possessor. Children 12 months old exhibited the highest frequency of…

The purpose of this research was to examine 18- to 30-month-old children's use of scripts for representing common events. A script is defined as a model that specifies the roles and props appropriate to an event and identifies a sequence of acts for achieving the goal defined by the event. Two aspects of script knowledge were investigated: (1) the…

Between their second and fifth years, young children learn approximately 15 new words a day. For every word the child hears, he or she must choose the correct referent out of an infinite set of candidates. An important problem for developmental psychologists is to understand the principles that limit the child's hypotheses about word meanings. A…

Nine individual prosocial child behaviors of 2-year-olds were obtained from mothers and caretakers. These behaviors were combined into a fourfold scheme which was then used to assess child prosocial behavior outside a laboratory setting. In addition, the two dispositional attributes of sociability and happiness were assessed. Observations of 28…

Recent work suggests that the apparent shift from thematic to taxonomic concept organization reflects changes in children's preference for these forms of organization, rather than their capacity. A study was made to assess toddlers' knowledge of the different possible relations for the same concept and to extend the triad method to children under…

In order to examine the development of social pretend skills in the toddler period, social pretend play was observed in same and mixed age dyads. More complex social pretend play was expected in the mixed age than in the same age condition. A second purpose of the study was to compare 5-year-old children's attempts to communicate pretend meanings…

Focusing on gender as a stimulus variable, this study explored whether performer and respondent's gender and ethnicity would affect the labeling of toddler behavior. In addition, such demographic variables as age, education level, and contact with children were investigated. From a subject pool of 928, a total of 528 subjects were drawn, equally…

Development of toddlers' combinatorial skills was examined in the domains of object manipulation, symbolic play, motor imitation, language, and peer interaction. Additionally, task demands that might produce variations in age-related patterns within or between domains were examined. Data were collected in free play sessions and during structured…

This investigation addresses problems of defining verbal imitation, and suggests solutions by analyzing verbal interactions between two children and their mothers. Children were between 18 and 35 months old, with a mean length of utterance between 1.4 and 4.2 morphemes. Analyses focus upon the uses these children made of maternal models; 10…

Age, specific emotion, and linguistic modality (verbal vs. non-verbal) were predicted to affect knowledge of emotion in young preschoolers (N = 45, mean age = 40.7 mos). Prosocial response to emotion and knowledge of emotion were also predicted to be related, given naturalistic observation and the use of contextually valid emotion knowledge…

On the basis of two sets of videotaped observations collected on same-sex, same-age and mixed-age dyads composed of children 18 and/or 24 months old, issues concerning research on infants and toddlers are addressed. The first set of observations was a simple description of the structure and content of children's peer interaction during 15 minutes…

A total of 41 preschool children, either 2 or 3 years of age, and their mothers were randomly assigned to two treatment groups: a microworld computer experience designed to teach the concept of inside/outside and an alphabet computer experience designed to drill ABC's. Videotapes of mother/child dyads were coded and scored using a revision of the…

Examined in a longitudinal study of children were correspondences and correlations between early language development on the one hand, and the manipulation of objects and play development on the other. There were developmental correspondences between the onset of five language landmarks (the emergence of first word, referential word, demonstrative…

A study was conducted to compare experiential features of mother/toddler interaction and maternal perception of toddler temperament in two ethnic groups: Chinese-Americans and European-Americans. Subjects were 16 mother/toddler dyads with five girls and three boys in each group matched for sex, age, and birth order. Caucasian mothers were…
