Thirty-five children who had participated in a study of mastery motivation at one year of age were reevaluated at 3.5 years. Findings differed for boys and girls and indicated that a wide range of behaviors in the cognitive-motivational domain must be examined to find developmental continuities. (Author/CB)

Provides evidence indicating a strong connection between a high level of ambient household noise and intellectual deficits at stages of infant development. Observers rated noise level from all household sources (stereos, appliances, etc.). Delays were found in sensorimotor development with high levels of noise. (Author/JN)

A study of the development of abstract noun definitions in children and adolescents had as its subjects 120 students evenly divided into age groups of 10-, 14-, and 18-year-olds, randomly selected from students scoring in the 40th to 88th percentiles on the Iowa Test of Basic Skills (for 10-year-olds) and the Tests of Achievement and Proficiency…

This study examined the social labels which are first used by infants, social differentiation on the basis of labeling behavior, and overgeneralization of social labels. Subjects were 81 infants from 9 to 36 months of age. The 9- to 24-month-olds were shown slides of themselves, their mothers, their fathers, and unfamiliar children, babies, and…

Examined data from 408 pairs of identical, same-sex fraternal twins at 14, 20, and 24 months to assess cognitive development and to identify genetic and environmental influences on phenotypic similarity. Found various patterns of development for separate constructs, for females versus males on each construct, and for individuals across constructs.…

Discusses humor development in children and other factors that influence children's interpretation and enjoyment of literary humor. These factors include the child's cognitive and linguistic stage of development, the object of humor, sex differences, and past experiences. (BB)

Discusses the vital importance of the preschool period in educational terms and maintains that early influences are much more effective than later experience; one cannot look upon nursery schools as merely child care services. (MS)

Examines mothers' and fathers' speech for similarities and differences as expressed in four categories of messages to their preschool daughters and sons: plans, strategies, symbolic play utterances, and extrasituational references. (MP)

Examined how quality of center-based child care related to early cognitive and language development from 6 to 36 months among 89 African American children. Found that higher quality care was related to higher measures of cognitive, language, and communication development, even after adjusting for selected child and family characteristics.…

Examined in six experiments toddlers' use of syntactic cues to learn proper names and count nouns. Found that by 24 months, both girls and boys were significantly more likely to select a labeled object if they had heard a proper name than if they had heard a count noun. At 20 months, neither girls nor boys demonstrated this effect. (Author/KB)

The extended effects of two instructional approaches, the Coordinated Basal Language Arts Approach and the Integrated Experience Approach to Communication, on pupils' language development at the second- and third-grade levels were investigated. Original subjects were 669 first graders who were pretested for readiness and intelligence. Of these,…

To aid in providing remediation for the language and cognitive skills of disadvantaged children, the UCLA Head Start Research and Evaluation Center compared three language programs: the UCLA Preschool Language Program, the Behavioral Research Laboratories' Readiness for Language Arts Program, and an unstructured Placebo Program. Each of the…

In an effort to describe the linguistic relational categories used by elementary school children, 75 children in grades one through six were asked to complete a puzzle by placing each of three identical triangles on a drawing of a fish, one on the dorsal, one on the ventral, and one on the tail. A piece of Velcro was attached to the back of two…

Explores the underlying knowledge that children have about the relationship between the structure of requests and the relative status of speakers and listeners. Shows that the three age groups (preschoolers, 5-year-olds, and 10-year-olds) could systematically differentiate the requests by means of syntactic directness or semantics. (HOD)
