Two strategies that children use to figure out new word meanings--attention to linguistic form class and the assumption of lexical contrast--were examined. It was found that very young children use both form class and lexical contrast to interpret new words. (PCB)

Introduces the Social Relations Model as a new approach for understanding reciprocity during parent-child and sibling play. (PCB)

Sex cleavages in toddler and preschool peer groups were investigated in two studies. In the first study, playmate preferences and initiations and responses to friends were examined during the free play of toddlers in day care centers. In the second study, cross-sex friendships in toddlers and preschool children were examined. (PCB)

Based on observations of children ages 21-25 months in play groups, investigates reactions of both peers and teachers to behaviors that could be identified and coded as male, female, or neutral. (Author/NH)

Strategies young children used to correct errors in nesting seriated cups changed substantially with age, becoming increasingly more flexible and involving more extensive restructuring of the relationships among the cups. The same trend toward increasing flexibility of thought and action also appeared in procedures children used to combine the…

The relationship between early language and cognition was studied in 20 children between 1 and 2 years of age. Four cognitive areas were tested: object permanence, means-end, play, and imitation. Results indicated that specific cognitive skills seem temporarily associated with some linguistic abilities, although attainment of skills can be…

Seventeen toddlers with specific expressive language delay were compared to two control groups on measures of spontaneous and imitated gesture production. Late talkers performed like age/comprehension-matched controls on gesture production and later appearing symbolic gestures and performed like language-matched controls on earlier appearing…

This study of 59 children (ages 1-3) at risk for severe mental retardation suggests that subjects exhibited repetitive motor behaviors topographically similar to those exhibited in typical infant development; there were significant age differences in expression of these behaviors; and a small percentage of these children exhibited atypical…

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…

Two studies concerned with agreement in ratings of temperament are reported. Ratings of the mothers of toddlers versus daycare workers were compared on the Toddler Temperament Scale (Study 1), and on ratings of a videotape of a 2-year-old child for responses relevant to six dimensions of temperament (Study 2). (Author/BN)

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)

Examines 2,000 Strange Situation classifications obtained in eight different countries. Differences and similarities between distributions in classifications of samples are investigated using correspondence analysis. Substantial intracultural differences are established; data also suggest a pattern of cross-cultural differences. (Author/RWB)

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)

Measures fathers' and mothers' linguistic involvement in the development of communication between young siblings--infants and toddlers. In a laboratory setting, 39 families, each with a mother, a father and two children, were videotaped in semistructured activities. Results suggest that fathers very actively direct sibling interactions, especially…

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…
