Age and instructional differences in the representation of pictorial information were investigated in a recognition memory task. A total of 56 nursery school and 40 college-age subjects observed pictures under name labeling, color labeling, imaging, and no label instructions. Subjects were then tested for retention of object identity and color…

This final report discusses research and literature analyses concerned with the attentional mechanisms in children's learning and analysis of cognitive changes from ages 5 to 7. The long-term objective of the project was to relate knowledge about children's attention and learning to issues of educational practice. The project focused its efforts…

A dissertation proposal involved a study to observe spontaneous behavior of children in interaction with materials in order to gain understanding of the factors that influence classificatory and imaginative behavior in free play. Children at two levels of ability in terms of classification skills were observed in interaction with materials at two…

This study examined the transition from concrete to formal operations in very bright children in an effort to determine whether high ability in concrete operations would carry over into formal operational ability, and also to investigate precocity in regard to formal operations. Subjects were 38 white middle-class children ranging in age from…

The purpose of this study was to compare performances by Japanese and American children on the Matching Familiar Figures Test, the primary measure of cognitive tempo. Data on more than 3400 Japanese and American children (approximately half male, half female) were used. Factorial analyses of variance revealed significant age x nationality…

Children's self-control behavior in motor and cognitive tasks was examined in a series of two studies in which modeling and self-regulatory mechanisms were varied to assess the influence of each. In the first study, 6-, 7-, 9-, and 11-year-old children individually played a 20-trial game of 'Simon Says' (involving activation and inhibition trials)…

The relationships among the perception, representation, and construction of series are examined within a model of the acquisition of seriation abilities. The model is then related to two experiments with three-, four- and five-year-olds. The key feature of the model is the delineation of parallels among developmental changes in three arenas:…

This paper describes a series of studies which examine the early development of recall. Subjects were children about 2 1/2 and 5 years of age. Recall was tested on nine-item lists which were either composed of three objects from each of three conceptual categories or nine objects from nine different conceptual categories. Age differences were…

The relation between conceptual development and visual exploratory behavior was investigated by engaging eighty-four 3-, 4-, and 8-year-old children in a picture-sorting task to determine whether they would spontaneously and readily discriminate between animate and inanimate objects. (Author/JMB)

Available from: Ablex Publishing Corporation, 355 Chestnut Street, Norwood, New Jersey 07648. Two groups (high and low functioning) of educable mentally handicapped children consisting of 70 Ss' average age 127 months' were tested for strategies in their approach to memory and problem solving tasks and for their responsiveness to strategy…

Reports on interplay between social and developmental processes in children's numerical understandings in working- and middle-class home settings. Methods included interviews with 78 children aged 2 1/2 and 4 1/2 years to assess their numerical understandings, interviews with the mothers about their children's everyday number activities, and…

Black children (N=233) from three age levels and two socioeconomic (SES) levels were given five Piagetian tasks to determine if differences in sex were associated with differences in cognitive development levels. Results showed that higher SES children performed better than lower SES children on all five measures of reasoning, seriation,…

Investigates the extent to which sex stereotypes impose competence (e.g., not knowing about objects) versus performance limitations (e.g., not performing for lack of reward) and the effects of sex stereotypes on exploration among 56 4- to 9-year-old children. (HOD)

A standardized open-ended interview was used to study how children, four to eight years of age, judge their own and their classmates' abilities. Self-ratings declined with grade, but peer ratings did not. Evaluation differences are discussed in terms of cognitive development and changes in the educational environment. (BS)

Criticizes Dorval and Eckerman (included in this issue) for their findings' lack of generality due to the artificial nature of the conversational groups studied. Also both age changes in the ability to plan large conversational units and the functions of particular kinds of turns within these larger units are left unexplored. (CB)
