Depending on age and the demands of the task, people may use different processing strategies in object categorization. Three-year-olds used a wholistic approach with strong effects of object typicality on three categorization tasks. Older children and adults showed differential effects of typicality, suggesting various strategies including…

Examined whether 2-year-olds can learn a novel part name of an unfamiliar object when adult demonstrates action upon object. Asked 24 Japanese 2-year-olds to choose referent for a whole object and part of the object in forced choice tests. Found that young children are able to override whole object assumption when actions of parts of objects are…

This study was designed to examine effects that access to manipulatives in science instruction have with respect to the development of spatial conceptual abilities and whether the effects were different for males and females. A secondary purpose of this investigation was to examine what relationship sex and access to manipulatives in conjunction…

The manual development of 148 blind, visually impaired, and visually impaired multi-handicapped students, aged 3-19, was studied. Results indicated a significant relationship between object manipulation and speech, and an inverse relationship between object manipulation and stereotypic hand mannerisms. Optimal development of manual functions and…

This paper reports on an experiment undertaken to delineate more clearly the relationship between the naming process in children and certain aspects of the environment which may play a role in that process. The investigation concerned the effect of manipulation and of object novelty on naming. Sixteen children, ten girls and six boys, ranging in…

A series of Piagetian concrete operations period tasks dealing with classificatory concepts was administered to 280 children (40 subjects from each of seven levels--preschool, kindergarten, and first, second, third, fourth, and sixth grades). Significant main effects for age were found for all the tasks. Few significant sex differences were…

Five- to six-year-old children estimated the size of Euclidian objects using an addition rule of Height plus Width, rather than a multiplying rule. Within the framework of information integration theory, tested whether intensive handling of objects would facilitate shift from addition rule to multiplication rule. Found that following handling,…

A study was designed to determine the effects of various ball sizes on children's catching ability and to examine the results as a between- and within-group factor. It was believed that the use of the two-test design would help to establish the validity of past and future tests of this nature. The between-subjects design group consisted of 48…

This study explores a learning model which suggests that a concept is acquired first through manipulation of concrete objects followed by transformation of the concrete objects into semi-concrete representations, followed by internalization of the concept through abstract representations. Microcomputer simulations of manipulative activities were…

This article discusses the challenge mathematics educators face in deciding what and how mathematics is to be taught, and offers some suggestions for teachers of young children based on Piaget's developmental theory of mathematics. Piaget's cognitive stages are briefly described and the concrete stage, which spans the age range included in early…

This study compared successive formats (booklets) to simultaneous formats (display boards) to determine whether simultaneous formats increase instructional effectiveness and whether a topic of higher interest provides more learning than one of lower interest. Findings suggest older children may achieve higher learning levels with simultaneous…

Synergistic psychology has been proposed as a meta theory for synthesizing different psychological theories into an explanation of how social, cognitive, and biological factors interact in human behavior. The basic theoretical assumption in synergistic psychology is that internalized social interactions become higher mental functions that regulate…

Investigated effects of limited oral/physical teacher intervention on object manipulation by preschool/early elementary children (N=70). Experimental students had magnets placed in their hands and were orally invited to explore. Results indicated differences between experimental/control groups in time spent with objects, number of activities…

This paper describes two empirical studies which investigated the importance for spatial learning of view control and object manipulation within 3D environments. A 3D virtual chemistry laboratory was used as the research instrument. Subjects, who were university undergraduate students (34 in the first study and 80 in the second study), undertook…

The purpose of this study was to assess the effectiveness of two generative learning strategies, concept maps and manipulation of objects, and to determine if either works better with individual learners or in cooperative learning groups. A total of 80 sixth-grade students in science education were randomly assigned to group or individual…
