Seventy-four lower- and middle-class children aged 2 1/2, 3 1/2, and 4 1/2 years, who were successful at unidimensional sorting of two objects by either color or form, were given feedback for correct bidimensional sorting of three objects, two of which had been used in unidimensional testing. Results indicate that Piagetian centration is a task-…

One hundred and sixty subjects from five age levels ranging from 3 to 20 years compared photographs of dogs (e.g., two different Great Danes or a Great Dane and a Doberman pinscher) and judged whether they were similar or different. (Author/MP)

Investigated the development of classificatory organization. Two experiments examined age differences in children's spontaneous extensions of a classification and a third examined children's extensions under hypothesis-testing instructions. (JMB)

A sorting presentation procedure was used to study the effects of three classification schemes (self-generated, thematic, or taxonomic) on the organized free recall of second and fifth graders. (Author/SB)

Classified children's use of cognitive strategies on a multitrial sort-recall task. Compared to fourth graders, more second and third graders were classified utilizationally deficient; fourth graders were more likely to be classified as quasi-utilizationally deficient. Levels of recall and clustering were higher for younger utilizationally…

Adults and five and seven year olds were presented with slides of facial expressions with different parts of faces exposed. Subjects judged either discrete emotions of happiness, surprise, fear, and anger or global emotions of feeling good and bad. Subjects more easily recognized global than discrete emotions. (BC)

Explored the role of motion versus shape in children's categorization of animal and non-animal kinds. Found that 4-year olds significantly used motion cues over shape cues to categorize objects. Seven-year olds and adults tended to use motion more than shape to categorize animals but not geometric figures. Findings support view that children are…

Trial-by-trial strategy assessments and a microgenetic design were used to examine the learning of rules for solving balance scale problems by 70 4- and 70 5-year olds. Developmental differences in learning that emerged seemed to reflect both distal and proximal influences. Encoding and initial rule use were related to different learning process…

Two experiments tested a model of young children's induction that specified contributions of linguistic labels and perceptual similarity to children's induction. Results support model predictions and point to a developmental shift, from treating linguistic labels as an attribute contributing to similarity to treating them as markers of a common…

The ability to perform induction appears early; however, underlying mechanisms remain unclear. Some argue that early induction is category based, whereas others suggest that early induction is similarity based. Category- and similarity-based induction should result in different memory traces and thus in different memory accuracy. Performing…

The aim of this study was to explore motor development in children with cerebral palsy (CP) using developmental curves for CP, subtypes, and the five severity levels of the Gross Motor Function Classification System (GMFCS). The Gross Motor Function Measure (GMFM) and the GMFCS were applied to 317 children (145 females, 172 males) with CP, aged…

The purpose of the present study aims to investigate the relationship between circadian typology and learning-thinking styles conceptualised as a preference toward information processing typical of the right vs. the left cerebral hemisphere. A sample of 1254 undergraduates (380 boys and 874 girls; mean age=21.86+/-2.37,) was administered the…

The National Child Count of Children and Youth who are Deaf-Blind is the first and longest running registry and knowledge base of children who are deaf-blind in the world. It represents a 25-plus year collaborative effort between the National Consortium on Deaf-Blindness (NCDB), its predecessors and each state deaf-blind project throughout the…

The classification behavior of male and female college students was compared with that of healthy, well-educated older males and females. On the whole, the results failed to confirm other published evidence maintaining that aging is marked by conceptual deficits or a regressed mode of cognitive functioning. (Author/CS)
