Analyzes the relationship between the development of formal operations and the development of the adolescent personality, as hypothesized by Inhelder and Piaget. It is suggested that the concepts of possibility and reflectivity have a variety of meanings, and that once these meanings are examined, the logical foundation for the…

The study examined the relationship between cognitive performance and the use of private speech in 20 learning disabled children, aged 81 to 108 months. Half of the children were hyperactive. Each child was given a series of cognitive tasks and played alone in a room for 7 minutes. Videotapes of the free play were later transcribed and coded…

The study examined the level of formal reasoning in mathematics of 70 learning disabled (LD) and 30 nonLD students from seventh and eighth grades. A review of previous research led to the hypothesis that mathematics interventions for LD students should involve concrete or pictorial, in addition to symbolic, representations of mathematical…

This research investigates the amount of metalinguistic knowledge one can assume when teaching an adult to read. In addition, it questions the source of this awareness and whether it relates to general cognitive development, to schooling, or specifically to the act of learning to read. The subjects were sixty monolingual adults enrolled in a…

The study involving 170 children (3-6 years old) investigated attention as a construct of three components and as an integrated cognitive process. Literature was reviewed which related to the components of attention, the development of a theoretical model which synthesizes attentional components with an ongoing process, the development of…

This is one of a series that is a collection of translations from the extensive Soviet literature of the past 25 years on research in the psychology of mathematics instruction. It also includes works on methods of teaching mathematics directly influenced by the psychological research. Selected papers and books considered to be of value to the…

This study investigates the ability of 13-month-old infants to use objects of varying degrees of realism in symbolic play and the genera1ization of this ability across different scene content. The effects of order of presentation of the task and of the behavioral coding scheme on the assessment of those abilities were also examined. Thirty male…

This study assessed the accuracy of judgments of 100 school-age children (5-11 years of age) as to the presence of real fruit content in three sets of cereals and beverages advertised on TV: real fruit, nonfruit, and artificially flavored products. In the baseline session accuracy increased with age, but children at each age misjudged the real…

THE PRINCIPAL OBJECTIVES OF THIS STUDY WERE (1) TO DESCRIBE DEVELOPMENT STAGES OF STUDENTS FROM FIRST- THROUGH NINTH-GRADE LEVELS AS THEY AFFECT THE SOLUTION OF A THREE-DIMENSIONAL CLASSIFICATION PROBLEM, (2) TO UTILIZE THE INHELDER-PIAGET AND THE BRUNNER SYSTEMS OF DESCRIBING STAGES OF COGNITIVE DEVELOPMENT, AND (3) TO DETERMINE BY MULTIVARIATE…

The paper reviews literature on the relationship between food, nutrition, and learning with particular emphasis on impairments in cognitive development and learning which result from malnutrition. Considered are means of detecting malnutrition, allergy symptoms, and steps a teacher can take in educating students and families about nutrition. Among…

Jean Piaget's theory of cognitive development and David Ausubel's assimilation theory of learning are explicated and selected research involving both theories is reviewed in this paper. The two theories are compared on selected dimensions to demonstrate that they are compatible and that, in conjunction with one another, they form a strong…

In discussing the relationship between cognitive development (perception, pattern recognition, and memory) and reading processes, this paper especially emphasizes developmental factors. After an overview of some issues that bear on how written language is processed, the paper presents a discussion of pattern recognition, including general pattern…
