Stability and predictive validity in the language and play development of 41 toddlers were studied. Links between language and symbolic play of toddlers were examined at 13 and 20 months in terms of homotypic, heterotypic, or mediated models of association. In the homotypic model, performance on a variable is related to performance on the same…

The composition of young children's vocabularies in 7 contrasting linguistic communities was investigated. Mothers of 269 twenty-month-olds in Argentina, Belgium, France, Israel, Italy, the Republic of Korea, and the United States completed comparable vocabulary checklists for their children. In each language and vocabulary size grouping (except…

Immigrant (Japanese and South Americans in the United States) families' play was compared to play in families in their countries of origin (Japan and Argentina, respectively) and in a common country of destination (European Americans in the United States). Two hundred and forty 20-month-old children and their mothers participated. Generally, the…

Infants' habituation and mothers' encouragement of attention were assessed at 5 months. Toddlers' language comprehension, language production, and pretense play, and mothers' encouragement of attention, were assessed at 13 months. Examined the contributions of infant habituation and maternal stimulation to toddlers' cognitive abilities. (PCB)

Examined contributions of dimensions of maternal responsiveness to timing of milestones in early expressive language development. Found that maternal responsiveness at 9 and 13 months predicted timing of language milestones over and above children's observed behaviors. Responsiveness at 13 months was a stronger predictor of timing than…

Three studies explore the development of discrimination and memory for symmetry in preschoolers four to six years of age. Issues addressed include the young child's ability to discriminate and reproduce symmetry, and the effects of pattern orientation and complexity on the young child's symmetry discrimination and reproduction. Results indicate…

Examined relations among measures of child language derived from observations of 20-month-olds' speech with mothers, experimenter assessments, and maternal reports. Found that structural equation modeling supported strong relations among the three sources, the loading of multiple measures on a single latent construct of vocabulary competence, and…

This study compared multiple characteristics of girls' and boys' vocabulary in 6 different linguistic communities--1 urban and 1 rural setting in each of 3 countries. Two hundred fifty-two mothers in Argentina, Italy, and the United States completed vocabulary checklists for their 20-month-old children. Individual variability was substantial…

In this study of prominent characteristics of parenting in the United States, France, and Japan, 72 mother-infant dyads were examined. The study focused on three prominent interactive domains of visual and vocal exchange between mother and baby (nurturing, social exchange, and didactic stimulation), examining their frequency of occurrence and…

Discusses construction of the Hebrew Communicative Development Inventory (HCDI), an adaptation of the MacArthur Communicative Development Inventory (MCDI). The HCDI was administered to a stratified sample of Israeli mothers of 253 toddlers. Results are presented and compared with scores from the MCDI. Results indicate that conclusions concerning…

Reviews research on influences on children's symbolic play. Finds little support for the effects of child-adult symbolic play interactions on child solitary play. Discusses three theoretical perspectives that should support these effects: attachment, ethological, and scaffolding theories. Reconsiders the essence of specific variables affecting…

Parenting is a subject about which people typically hold strong opinions, but about which too little solid information or considered reflection exists. And clearly critical questions about parenting abound. Moreover, the family generally, and parenting specifically, are today in a greater state of flux, question, and re-definition than perhaps…
