The performance of 75 congenitally blind and 75 sighted subjects (6- to 18-years-old) was compared on 32 Piagetian measures of reasoning, moral judgment, and moral conduct. Among major findings were that blind Ss did not achieve the reasoning processes characteristic of concrete operational thought with the facility or completion that would be…

This paper focuses on a study which replicates and extends earlier work employing a recognition memory paradigm to investigate children's memory and developmental changes in dominant word associations. On the recognition test the implicit associative response can lead to better memory for the original items (this is the hit rate), and it can also…

The paper presented relates to a study done examining the ability of children from grades one through six to locate a point in one, two, and three dimensions and to order a temporal series of events in one, two, and three dimensions. The performance of the subjects was also used to examine a small part of Piaget's theory of cognitive development.…

The efficacy of small group instructional programs in classificatory, seriation, and combined class/series skills was evaluated for a sample of 60 urban, middle-class, 4- to 5-year-old children in a transfer of training design. Significant curriculum-specific transfer effects were found for the seriation instructional condition, whereas little…

This paper analyzes Brainerd's work in assessing the developmental sequence or ordination and cardination concepts of number, and describes a study which investigated the hypothesis that task-specific difficulty could explain Brainers's data. Three new tasks were designed for the assessment of ordination and cardination and administered to a…

A study was undertaken of the effects of formal education and conservation of numerousness on addition and subtraction problem types. Thirty-six kindergarten and 36 first-grade subjects randomly selected from one area of a school district were administered measures of conservation, problem-solving success, and modeling ability. Following factor…

The author considers memory as being composed of four categories. The fourth category--metamemory--refers to the individual's knowledge and awareness of memory or of anything pertinent to information storage and retrieval. It is that aspect of memory that deals with the how and what of memory itself. The paper first presents a model of what could…

This study explores the cognitive dimensions used by children in differentiating among television characters. Similarity judgments between all possible pairs of 14 television characters were analyzed using INDSCAL, a multidimensional scaling method which allows for individual or subgroup differences in scaling solutions. By linking the results of…

The purpose of this study was to investigate whether success in the Science - A Process Approach (SAPA) process of classification designed for primary grade children is contingent upon the children's developmental level as defined by Piaget's theory. The investigators sought to determine whether children who had reached the concrete operational…

A study was designed to investigate the relationship between cognitive style and hypothesis testing strategies used in solving concept attainment problems. A field-independent (FI) and field-dependent (FD) cognitive style group of third grade students were administered concept attainment problems using a blank-trial methodology. The results…

Three extrinsic factors were manipulated in a problem-solving task performed by 80 ten-year-old children of I Q 90-110. The factors were: the presence or absence of the name of the concept given in feedback, specific instructions, and whether the child was allowed to verbalize. The task was a modification of Vygotsky's experiment on concept…

Reported is a study based on the summary findings of a series of studies which indicated that many children who receive organized instruction designed around the few major concepts of science do, in fact, use scientific models to explain their observations of natural phenomena. The instruction that children in the study received was delivered by…

In this paper the author reviews and synthesizes the research literature concerning the developmental relationships between conservation of number and linguistic capability in handling of quantitative and relational terms. Several models for the development of these competencies are discussed. On the basis of this review the author concludes that…

This study investigated children's developmental differences in adopting a clustering strategy while studying items for later recall. The central focus was on developmental differences in the efficient use of study strategies, rather than clustering in recall per se. Twenty-four third- and fifth-graders and 12 college students were given a series…

The role of the family in the education of a young child, particularly during the first three years of life, is the subject of this symposium address. Four topic areas are identified as the foundation of educational capacity: language development, curiosity, social development, and cognitive intelligence. Professional educators, working directly…
