Reports the results of a multiple regression analysis conducted to determine, in a group of three- to six-year-old children, the magnitude of IQ variance accounted for by physical growth variables and socioeconomic status indicators. (RH)

A reading test was constructed in English, Japanese, and Chinese to assess the validity of the claim that children learning to read Chinese and Japanese do not evidence reading disabilities. Large samples of fifth-grade children in Japan, Taiwan, and the United States were given the test along with a battery of 10 cognitive tasks. (Author/RH)

Results obtained from 44 children (ages 7 through 16) with sex chromosome abnormalities and from 17 chromosomally normal siblings demonstrated that children in the former group have an increased risk of encountering learning problems. (MP)

Three experiments used adults' performances in a category abstraction paradigm to test for the existence of individual style in the drawings of three five-year-olds. Overall, studies provided experimental support for the notion that young children possess recognizable artistic styles. (MP)

In two experiments, children ages six through eight, 10-year-old children, and college students were shown several series of slides. Each series told a unique "story" and was followed by oral questions. Results illustrated the increasing interdependence of the verbal and visual systems with age. (Author/MP)

In order to determine whether non-Western children would show a memory deficit for contextually organized spatial ability, the performances of 30 Mayan and 30 American nine-year-olds on reconstruction of an organized three-dimensional miniature scene were examined. (MP)

In two experiments, the effects of modeling on multiple seriation and multiple classification skills in preschool children were examined. In the first study, children observed models who demonstrated either multidimensional grouping or ordering. In the second, children received only single classification training on the basis of form, color, or…

Tests the hypothesis that the presence of attentional deficits in autistic children interferes with their performance on tests of intellectual development and status. Twelve autistic, 12 normal, and 12 trainable mentally retarded children ages four through nine were administered six "Piagetian" tasks assessing performance at sensorimotor,…

Analyzes cognitive developmental changes in the use of a convention for measurement among New Guinea's Oksapmin people. A total of 103 individuals (including unschooled children, unschooled adults, second-grade children, and sixth-grade adolescents) were administered three types of tasks assessing ability to compare lengths. (Author/RH)

Compares developmental changes in the processing of subordinate/superordinate relationships across perceptual and nonperceptual categories. Perceptual categories contained visually similar exemplars, while nonperceptual categories contained dissimilar exemplars. Second, fifth, and eleventh graders, as well as mentally retarded adolescents,…

Examines the abilities of 50 children (10 each at ages 6, 8, 10, 12, and 14 years) to produce tag questions. Of particular interest was the determination of whether or not constituents of a correct tag are acquired at different ages. (MP)

In order to examine the effects of interrogative strategies in promoting children's associative learning, children five and six years of age, as well as sixth-grade children, were first presented with a variety of picture-paired associates and then tested for the ability to memorize them. (MP)

According to a new classification schema, data were obtained from both adults and children on article usage in English. The sample included children in the initial period of article acquisition (from two to three years of age). Results are discussed in terms of age differences and children's levels of difficulty. (MP)

Twenty preschoolers and 10 student teachers were asked to reconstruct the complete layout of their classroom by using a small-scale model as well as by using life-size furniture in the classroom itself. Children's performances were significantly better in the classroom than they were on the model. (Author/MP)

Two experiments tested the effectiveness of familiar size as information for perceiving distance. In the first experiment, under monocular viewing conditions, adults judged the distances to large and small photographs of faces and to large and small checkerboard ovals equal to the faces in size. In the second, the same displays were presented to…
