Two studies are reported which demonstrate a positive relationship between sociometric status (after two weeks of intense social interaction) and social acceptance judged from photographs by an independent group of peers. Acceptance was found to be related to physical attractiveness. (ST)

Developmental changes in interpersonal perceptions in older siblings were studied in children in grades K, 2, 4, 6, 8. Older children used more abstract and more nonegocentric modes of description. (ST)

Preschool children were trained to acquire transitivity, conservation, and class inclusion of length via feedback to their judgments. Feedback was found to facilitate the learning of all three concepts. (ST)

The development of the ability to selectively oppose fingers to the thumb and to localize digits was studied in preschool children. Competence increased with age. Results are discussed in terms of the development of body schemata and neuropathological conditions. (ST)

Differential fixation to novel stimuli was obtained from 4-month-old infants to test the discrepancy hypothesis, which predicts a curvilinear relationship between degree of discrepancy and attention. (ST)

Recognition memory, defined by novelty preferences, was found to vary over 4 discrimination tasks as a function of length of familiarization for 5-6-month-old infants. (ST)

Three experiments assessed the ability of 2 to 5-year-old children to infer, under very simple task conditions, what another person sees when viewing something from a position other than the children's own. (ST)

Discrimination learning studied in 3-year-olds, indicated that children over 30 months of age did better than younger children, and girls learned faster than boys after the first problem. (ST)

Young children usually prefer to classify objects on the basis of shape rather than color. The present study explored this phenomenon with a stimulus matching test and a component selection test. (ST)

Subjects from urban and rural Yucatan were tested on a short-term and incidental memory task. Urban subjects were in school, whereas most rural subjects were not. Results indicated that formal schooling is an important factor in the development of mnemonic skills in short-term memory. (ST)

Two experiments sought to determine whether rehearsal strategies constitute a primary determinant to age-related changes in auditory short-term memory. (ST)

This study compared the abilities of good and poor readers (sixth grade boys) to attend selectively in a reading situation. Results are discussed in terms of an analysis-by-synthesis model of reading for meaning. (ST)

The Piagetian concept of horizontality was studied in 195 fifth graders to determine the relationship between this concept and memory. (ST)
