Children (2;10 to 4;7 years) taught passive sentences with forms employing animate patients could produce and comprehend passives better than children taught with forms employing inanimate patients. This indicates that "perspective" is the cognitive counterpart to the formal category of subject and that language acquisition is connected…

Examines gender stereotyping in children's picture books. A survey of current material indicates only a small increase in the number and prominence of female characters. Discusses the history of gender stereotypes in children's literature and their effect on cognitive development. (DM)

Guidelines are given for teaching basic concepts (such as "above,""least," and "different") to students who are educable mentally handicapped. Stressed is direct and systematic instruction in basic concepts as an integral part of the curriculum with concrete, representative, and abstract applications. (DB)

Two studies investigated the maintenance of focused attention in the first five years of life. Findings revealed changes over age in the way children concentrate and sustain attention spontaneously during free play. Results point to possible developments underlying the increasing duration of focused attention. (RH)

Discusses domain-specificity with regard to social and cognitive development. General epistemological and theoretic considerations of the study of cognitive development are discussed. Included is a consideration of the intersection of the interactional model and a classification of systems of knowledge. (RH)

Suggests that the invention and construction of traditional American Indian string figures possess elements associated with mathematical thought: logic-intuition, generality-individuality, and analysis-synthesis. Contains 16 references and several historical observations of string figures. (SV)

Reviews genetic influences on learning disabilities, discussing recent advances in molecular genetics that have made linkage analysis a more powerful tool for studying the genetics of behavioral phenotypes. Also examines what is known about genetic influences in two familial disorders, developmental dyslexia and Tourette syndrome. (Author/NB)

Findings on 20 children who passed an area conservation task and 20 who didn't suggested that conserving children applied an additive rule, while nonconserving children presented patterns suggesting centration on one of the two dimensions. Implications for Anderson's and Piaget's conceptions of conservation development are discussed. (RH)

Compares and synthesizes past decade of research into facets of wisdom, searching for a unified definition. Concludes that factors relating to wisdom (age, experience, intelligence, knowledge, intuition, common sense, and personality) can be unified theoretically if wisdom is viewed as the recognition of and response to human limitation.…

Investigated the ability of 56 children of 2-4 years to deceptively lead others into false beliefs. Results show that 2 1/2-year-olds already practice a variety of deceptive strategies that presuppose an operative theory of mind. (RJC)

Proposes an interference explanation of data from dual-task studies of memory development. Dual-task data support the resources hypothesis that memory processes tax a common pool of cognitive energy, which has been variously called attentional, mental effort, and working-memory capacities. Suggests that dual-task deficits are instances of output…

Explored mechanisms responsible for improvements in short-term memory in early to middle childhood. Recall and speech rate for acoustically similar and dissimilar words and words of differing lengths were assessed in three groups of children of 4 to 10 years. (RH)

Investigated infants' integration of visual information across space and time. In four experiments, infants aged 12 months and 6 months viewed objects after watching light trace similar and dissimilar shapes. Infants looked longer at novel shapes, although six-month-olds did not recognize figures taking more than 10 seconds to trace. One-year-old…

Investigated the development of social referencing (children's looks toward parents, instrumental toy behaviors, affective expressions, etc.) in 40 infants aged 6-9, 10-13, and 14-22 months. Results indicated that looking behavior of younger children may function differently from that of older children, and social referencing involves a number of…

Measured covert shifts of visual attention of observers aged 6, 8, and 20 years in a speeded classification task. There were differences between children's and adults' attention orientation, target processing, and use of predictability in cues. (SAK)
