Investigates young children's ability to adjust the content of their verbal responses according to what they know their listener knows. Younger and older three-year-old children were able to discern what another person knew and did not know and adjusted their responses accordingly. Younger three-year-olds tended to be underinformative. (SED)

Observed a group of 46 children classified at 20 months as either behaviorally inhibited or uninhibited, and 18 children who were classified aa falling at neither extreme at 5.5 years of age, in contexts designed to evaluate behavior in social situations and heart rate, heart variability, and pupillary dilation to cognitive tasks. (HOD)

Compared 12 right-handed adolescent females with a history of idiopathic precocious puberty to 12 closely pair-matched normal controls of similar maturational status to test the association of physical maturation with cognitive abilities and the mediation of this association by hemispheric specialization. (HOD)

Reports on a study of mothers' uses of nouns and pronouns and their references to objects and persons as environmental variables which might relate to children's nominal preferences. Findings suggest that environmental factors do contribute to stylistic differences in language acquisition and that the communicative functions of language are an…

Reviews studies of cognitive development of high school students in small rural schools. Finds that while research clearly shows that students in small rural schools may not be as intellectually developed as students in large schools, little research has been done to identify possible causes for this difference. (BRR)

A social studies concept assessment instrument was developed and used to assess the concept development level of 24 kindergarten and 28 first grade subjects on n social concepts. Significant differences were found in scores for kindergarten and first grade; no significant differences were found in scores for race or sex. (Author/RM)

On the basis of a study involving 40 first-grade students, compares Pascual-Leone's and Keating and Bobbitt's developmental theories of information processing by contrasting their predictions about a classification task. Results falsified Keating and Bobbitt's model. Predictions from Pascual-Leone's theory were almost wholly confirmed. (RH)

In an attempt to validate the findings of other researchers regarding the development of conceptual perspective taking, this study used Taylor's (1988) 2-tiered model to examine development of perspective taking among 40 3- to 5-year-olds. Participating were 22 males and 18 females from English-speaking backgrounds attending a preschool in…

Reviews some better known Piagetian scales; analyzes and compares Piagetian-based and conventional intelligence measures. Reviews research comparing the two methods and examines whether racial groups' performance differs on Piagetian measures. Discusses the implications of Piagetian assessment procedures for school psychologists. (Author/RC)

Examined one-year follow-up data on a cognitive-behavioral treatment. Improvements were found for subjects in all treatment groups, and these effects were attributed to increased age. Results indicated that conceptually trained children showed significantly better recall of the material than either concrete trained or control group children.…

Compared to a peer group of average abilities, gifted and talented junior high school students appeared more outgoing, participating, insightful, fast-learning, intellectually adaptable, conscientious, persistent, and moralistic, thus indicating significant between-group differences. (SB)

Both right-and left-handed normally developing 6-year-olds showed considerable evidence of bilateralization of hemispheric functions for spatial and verbal information processing; the slowly developing children (ages 5-9) exhibited unusual patterns of hemispheric specialization usually opposite those typically expected in children or adults.…

Participants aged 17-26, 39-51 and 59-76 solved concept problems to investigate intellectual correlates of concept identification as a function of stage of learning in adulthood. Differential ability-performance relations as a function of stage of learning were considerably less potent in the elderly v the young and middle aged. (Author)

Compared comprehension of novel communicative signs to assist 2.5- and 3-year-old humans, chimpanzees, and orangutans find hidden objects during a hiding-finding game. Found that children at both ages performed above chance with all signs. No ape performed above chance for any signs not known before the experiment despite three times as many…
