Examines the nonverbal communication competence of 18- to 48-month-old Down Syndrome children. Results indicate that Downs children display strengths and weaknesses in nonverbal communication skills. Further, results suggest a deficit in expressive language is associated with a deficit in nonverbal requesting skill that had developed earlier among…

Assesses the interrelations among the functional properties of maternal speech, the structural properties of maternal speech, and child language growth for a period of six months for 22 two-year-old children and their mothers. (HOD)

Investigates differences in the language learning environments of six twin pairs and 12 singleton toddlers (all firstborn) with special reference to pragamatic factors that might be expected to differ in dyadic and triadic interactive situations. (HOD)

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…

Four toddlers with mental retardation were studied in the context of a multiple baseline across subjects design. Results supported the use of a modified version of milieu teaching to increase intentional requesting by these children. Increased intentional requesting was generalized to interactions with mothers. (Author/DB)

This study of 18 mothers and their legally blind children, aged 20-36 months, found that the overall home environments were favorable. Home environments were not significantly related to any developmental scores except for the positive relationship between the emotional and verbal responsiveness of some mothers and the expressive pragmatic…

This observational study examined the development and use of communication in a pair of deaf and hearing monozygotic twins from 13 to 36 months of age. Both children were enrolled in a total communication preschool program. In contrast to the hearing twin, the deaf twin used imitative (rather than responsive) signs and gestures. (Author/DB)

This study examined effects of simple switch-activated toy use and switch-activated computer program use with two children (ages 2 and 3) with severe and profound disabilities. Highest independent switch activation, orientation to the stimulus, and attention to the stimulus were found for both subjects when both the computer programs and the toys…

This study, involving 67 children (ages 2 to 60 months) with motor delays, found that the Battelle Developmental Inventory (BDI) possessed moderate to high levels of concurrent validity with appropriate subtests from the Vineland Adaptive Behavior Scales and the Bayley Scales of Infant Development. (Author/JDD)

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…

Written in German, this article demonstrates the influence of different types of contingency information on the development of infant's locus of control and causal attribution, and discusses empirical models for calculating contingency parameters of the microsocial environment of infants, toddlers, and preschool children. Models discussed include:…

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…

To determine the impact of quantitative and qualitative aspects of fathering, relationships among father involvement in childrearing, parenting characteristics, and child adaptation were investigated. Results from 70 infants 20 months of age and their parents highlighted the salience of qualitative characteristics of parenting for toddler…
