Explores the relations among combinatorial capacities in language, symbolic play, blockbuilding, and nonsemantic action sequences within a sample of 18- to 24-month-old children, as well as assessing the developmental level of a selected subset of concepts. (HOD)

Tests the ability of 43 children, ranging in age from 20 months to 40 months, to discriminate between pictures of boys and girls and male and female adults. Compares children who passed this gender-task with those who failed it on three behaviors most often categorized as sex-typed: toy choice, aggression, and peer playmate selection. (HOD)

Observed play of 52 toddlers with a set of socially stereotyped masculine, feminine, and neutral toys in a day care setting over 14 months to (1) determine the age at which toddlers consistently exhibit sex-stereotyped toy choices in a natural setting and (2) investigate relation of parents' expectations and the children's own knowledge of gender…

Observed in group day care settings, responses to distress in peers were examined in 10 abused toddlers and 10 matched controls from families experiencing stress. Early development of "abusive" behavior patterns in toddlers who have been subjected to physical abuse and later behavior of abused individuals as parents are discussed in relation to…

Results indicated a fairly consistent relationship between Home Observation for Measurement of Environment (HOME) scores and children's developmental status in spite of the fact that there were some ethnic and social status differences in the relationship. Measures of specific aspects of the child's home environment were more strongly related to…

Individual differences in children's conceptual strategies at 3 years of age were predicted by aspects of children's behavior and language at 13 and 24 months. Production of pointing gestures at 13 months and nouns and attributive adjectives at 24 months were positively associated with the use of a taxonomic matching strategy at 3 years of age.…

Investigated whether otitis media (OM), middle ear disease, affected toddlers' attention to language. Children were studied during a picture book-reading task at high- or low-quality day-care centers. Children with chronic OM in low-quality care showed the most negative effects on attention during episodes of OM; mothers rated children with…

Examined mothers' representations of their relationship with toddler sons over a 13-month period. Found that the three factors characterizing mothers' representations for 15-month olds also fit data for 28-month olds. Found significant increases in anger but no changes in joy, pleasure, coherence, guilt, and separation distress. Changes in…

Compared performance of infants with autism, developmental delays, or normal development on a prospective screening instrument for autism. Found that 20-month-olds with autism lacked social gaze in empathy and joint attention tasks. Infants with autism or developmental delays demonstrated functional play. Few produced spontaneous pretend play.…

Used survival analysis to identify likelihood of placing an infant or toddler in child care, using data from a national probability samples of 2,614 households. Found that median age at first placement was 33 months, but varied by geographic region, mother's employment status during pregnancy, mother's education level, and family structure.…

This study examined the influence of maternal preconceptions on child difficult temperament at 6 months and maternal sensitivity at 12-15 months and whether all 3 variables predicted children's empathy at 21-24 months. Within a low-income, ethnically diverse sample of 175 mother-child dyads, path models were tested with 3 empathy indices…

Two hundred forty English-speaking toddlers (24- and 36-month-olds) heard novel adjectives applied to familiar objects (Experiment 1) and novel objects (Experiment 2). Children were successful in mapping adjectives to target properties only when information provided by the noun, in conjunction with participants' knowledge of the objects, provided…

Two longitudinal studies focused on naturally occurring conversations at home among (1) 18- and 24-month-old second-born children, mothers, and older siblings, and (2) first-born children 25 and 32 months old, mothers, and younger siblings. By two years of age most children referred to a range of feeling states in self and other, and discussed the…

Examined whether 30-month olds appreciate that their communicative signals are being understood by another. Separated listener comprehension from obtaining a material goal in communication. Children clarified their signal more when the experimenter misunderstood compared with when she understood. Regardless of achieving overt goal, children…

Assessed temperament of children of 5-42 months of age. A Q-sort measure was used to assess children's attachment security between 12 and 45 months. Analysis of results revealed an association between temperament and attachment security at all ages. (BC)
