To investigate developmental differences in timesharing performance, 60 boys, 20 in each of three age groups (7-, 10- and 13-year-olds), performed an auditory matching task and a tracking task alone and concurrently, the latter under two sets of instructions. Decrements produced by concurrent performance were compared for the three age groups.…

This dissertation abstract summarizes a research study which investigated the hypothesis that bilingualism in children would result in: (1) increased ability to analyze syntax; (2) acceleration in the time of arrival of the stage of concrete operational thinking; and (3) an increase in cognitive flexibility or ability to mentally shuffle material.…

Intended to introduce teachers to the concept approach in teaching social studies materials, the five chapters of this publication discuss (1) a definition of "concept" and the term's relationship to facts and generalizations, (2) the function of concepts in the social sciences, (3) how concepts develop, (4) how concepts are related to inquiry and…

Four experiments were conducted to assess the effects of certain stimulus variables on children's discrimination learning. In general, it was found that word frequency was negatively related to discrimination learning as long as the words were meaningful to the subjects. Moreover, the relationship between word and performance reversed in…

The aim of this study was to test a hypothesis derived from the Cognitive Clarity Theory which compares Indian and non-Indian children in two localities of British Columbia. It was hypothesized that, in comparison with Indian children, the non-Indian children would show significantly superior performance on objective tests of cognitive clarity in…

A dialogue between Jean Piaget and Lev Vygotsky is described and analyzed. Practical implications of the theoretical discussions between the psychologists are pointed out for parents, teachers, and other professionals who deal with children. Essential points of agreement for Piaget and Vygotsky concern the crucial role played by consciousness in…

This issue, part of an annual series prepared for Maryland educators, presents the problem solving aspect of learning behavior by reviewing some of the variables which affect how individuals confront intellectual problems. Selected studies and a bibliography which are helpful in developing instructional methods which take into account individual…

Mental ages for normals' and for retardates' achievement on 21 Piagetian measures of reasoning are presented in this exploratory longitudinal study. Before standardization data can be provided, a study which involves a more extended sample is necessary. It is, however, suggested that: (1) Normals' (IQ 90-110) transition from concrete to formal…

Preceded by three studies of preschool children, this research compared the thinking abilities of 5-year-old white and black children in relation to certain environmental factors. All of the 2413 children were chosen to conform with the earlier studies by having approximately one-fourth with mothers having graduated from college, one-half…

Reading comprehension questions selected from readers, teacher manuals, and workbooks of three current, widely used and representative basal reading series were analyzed according to the Barrett Taxonomy to determine cognitive objectives. The taxonomy has five major divisions and thirty-three levels within, claimed to be cumulative and sequenced…

This study was intended to obtain baseline data in the areas of verbal and cognitive behavior patterns of selected secondary social studies teachers. Hypotheses for study were that there will be no significant difference between: 1) observed verbal teaching behaviors of the highest and lowest ranked teachers; 2) the observed cognitive behavior of…

The properties of written, textual language with which children deal in school can be distinguished from those of oral language by examining the manner in which interpersonal and logical functions are stressed and by assessing the degree to which interpretation is confined by meaning explicitly stated in textual matter. The developmental process…

Naming tasks were used in two studies to test for conceptual organization in young children by comparing the latencies for naming objects in primed vs. non-primed conditions. In the primed condition, a taxonomic category was primed by prior activation of a coordinate member of the same category. In Study 1, 54 kindergarten children were randomly…

This paper outlines the syntactic structures which represent a stage in the cognitive development of children, and focusses on an aspect of cognitive development known as conservation. The cognitive components of conservation are presented as the primordial base for the set of syntactic structures which map or mirror them. Piaget proposed four…

Head Start preschoolers on a Papago reservation in Arizona were subjects of two studies of the effects of televised instruction and directed participation on teaching enumeration and conservation skills. Television instruction was most effective when used with active directed participation and corrective feedback. (Author/JEG)
