Children with mental retardation have pronounced difficulties in using cognitive strategies and comprehending abstract concepts--among them, the concept of sequential time (Van-Handel, Swaab, De-Vries, & Jongmans, 2007). The perception of sequential time is generally tested by using scenarios presenting a continuum of actions. The goal of this…

The purpose of this study was to investigate the elementary student's concept of environmental image of favorite places. The research was based on drawings and verbalizations from two groups of students, one rural and the other suburban. Under such conditions, some general trends and conclusions concerning environmental images were observed. (MA)

Class-inclusion in first grade children was studied by using part-whole comparisons of families of stimuli (e.g., dogs). Results indicated that it was easier to make part-whole comparisons for the family relation than for the class-inclusion relation. (ST)

Children can recognize patterns much earlier than they can reconstruct them. A child cannot understand seriation in an operational sense unless he recognizes a seriated configuration. (ST)

Previous research has shown that 3- to 4-month-old infants form a global categorical representation for cats that includes female lions, whereas 6- to 7-month-old infants differentiate between cats and lions. Three experiments using familiarization-novelty preference procedures attempted to determine whether the differentiation of a global…

The purpose of present experiments with subjects approximately three, five, and seven years of age was to provide additional evidence for the obviousness of the generative transmission principle and to provide initial evidence for the secondary principles of absence and facility. Empirical support was found for each of these selection principles,…

Reports identical effects of verbal labels and perceptual cues in children's concept attainment. (ST)

Results support view that development of part-whole perception is mediated by logiclike perceptual regulations. (MH)

IN A REPRODUCTION TASK WHICH INCLUDED INSTANCES OF SEVERAL SCHEMATA MIXED TOGETHER, SUBJECTS LEARNED TO DISTINGUISH AMONG THE SCHEMATA WITHOUT KNOWLEDGE OF RESULTS. A BEST FITTING EQUATION DESCRIBING PERFORMANCE AS A FUNCTION OF NUMBER OF REPRODUCTION TRIALS ACCURATELY PREDICTED LEARNING WITH NEW SUBJECTS AND PATTERNS RANDOMLY SAMPLED FROM A…

The study explored ways in which congenitally blind children group objects and words, revealing their level of cognitive development. Differences in patterns of response as a function of age and type of tasks are presented, and the implications of these findings for the education of this population are discussed. (Author/CL)

Piaget's use of the equilibrium model to define knowledge results in a cybernetic conception of knowledge that cannot explain how knowledge becomes possible. The knowledge that behaviors apply discriminately must be acquired, and cannot be programed, and therefore cannot be learned. (FG)

PIAGET'S THEORETICAL FORMULATION OF THE DEVELOPMENT OF CONSERVATION OF CONTINUOUS QUANTITY WAS EXAMINED. CONTROL SUBJECTS IN EACH OF TWO AGE GROUPS (5 AND 6 YEARS) WERE GIVEN A COMPLEX TASK SITUATION THAT IS TYPICAL OF PIAGET'S WORK. THESE SUBJECTS WERE ALSO GIVEN ANOTHER TASK, A MEASURE OF CONSERVATION OF QUANTITY THAT IS INDEPENDENT OF PIAGET'S…

MANY CHILDREN WITH CEREBRAL PALSY HAVE VARIOUS PERCEPTUAL HANDICAPS WHICH RESULT FROM THE NEUROLOGICAL IMPAIRMENT. TEACHING AIDS ARE DESCRIBED BY (1) NAME, (2) MATERIALS NEEDED IN CONSTRUCTION, (3) PICTORIAL REPRESENTATION, (4) EXPLANATION OF USE, AND (5) THE CONTRIBUTOR'S NAME. CATEGORIES OF AIDS INCLUDE (1) SENSORY DEVELOPMENT, (2) VERBAL…

This paper describes the mechanism of conceptual development by characterizing it as a cartooning process, which is a neurological mechanism which records a perceptual kind of sketch of the world in our brains. Its unique character, its biological basis, and its consequences for education are discussed. (Author/KC)
