This study examined the social labels which are first used by infants, social differentiation on the basis of labeling behavior, and overgeneralization of social labels. Subjects were 81 infants from 9 to 36 months of age. The 9- to 24-month-olds were shown slides of themselves, their mothers, their fathers, and unfamiliar children, babies, and…

A review of task analysis procedures beginning with the military training and systems development approach and covering the more recent work of Gagne, Klausmeier, Merrill, Resnick, and others is presented along with a plan for effective instruction based on the review of task analysis. Literature dealing with the use of task analysis in programmed…

This study examines the effects of using different classes of ratios on adolescent performance on proportionality problems. Problems of the form a/b = c/x varied on four dimensions: size of a/b, equality or inequality of b and c, complex or simple fractions, and form of the test. Tests consisted of six proportionality problems involving sizes of…

The Test of Logical Thinking (TOLT) is a written test of cognitive development constructed to be logically equivalent to specific Piagetian tasks. It consists of 36 open-ended items administered in a one-to-one situation. Subjects were middle to upper class, predominantly white elementary school students. The 168 students were randomly drawn from…

In this study, kindergarten children classified as impulsive received (1) visual analysis training involving either motor or verbal responses, (2) were trained only to delay their responses, or (3) were assinged to a control group receiving no training. While all treatment groups showed a significant decrease in errors on the Matching Familiar…

Three research studies were performed to assess patterns of memory organization with respect to complementary and similarity dimensions, referring to associations based on functional relatedness and grammatical relatedness, respectively. The first study failed to replicate the results of a study by Denney and Ziobrowski (1972), indicating that…

Eighth-grade subjects, classified as formal or concrete operational, learned a mathematical group structure with either a pre-determined sequence of trials (Reception Mode) or a free choice of trials (Selection Mode). All subjects learned a similar group structure one week later in the Selection Mode. Formal subjects learned in fewer trials and…

Piaget's theory of cognitive development is explained, especially in relation to the teaching of elementary school science. Several research projects involving Piaget's theories are reviewed. (MLH)

This book, containing conference papers and a summary of activities, focuses on the contributions which current research in cognitive psychology can make to the solution of problems in instructional design. The first three parts of the book include sets of research contributions followed by discussions: part one deals with different strategies for…

This study investigates the developmental changes that occur in the attending behavior of children engaged in a relatively simple classification task, and attempts to reaffirm the existence of developmental changes in stimulus preferences and in the ability to employ double classification systems. Subjects were 24 preschool and 24 first grade…

Studied were some cognitive aspects of the language development of a 2-year-old Puerto Rican boy who had been on the U.S. mainland 1 month. A Neo-Piagetian approach (developed by K. Witz and J. Easley) was used to study: language behavior as being embedded in more complex, unified systems; productivity of different structures and language…

Two experiments compared the cognitive maps (mental representations of the spatial environment) of first graders, fifth graders and college students, and investigated developmental changes in the ability to manipulate cognitive maps mentally. In the first experiment, subjects were asked to move from stationpoint to stationpoint and at each, to…

The effect of differential knowledge of a referent on children's communication effectiveness was investigated. A total of 40 boys and 40 girls from kindergarten and second grade were given one or three opportunities to explore a maze-like construction approximately 22 square meters in area. Each child was then required to verbally describe the…

The primary purpose of this study was to determine empirically whether an individual's cognitive style differentially influences his hypothesizing behavior within a relatively simple information processing task. A characteristic of cognitive style explored is the manner in which an individual perceives and analyzes a stimulus configuration;…

This study was designed to assess the effects of teaching the concept of interior volume, and methods of computing this volume, on the ability of fith-grade students to conserve volume. Conservation of volume was measured by an instrument developed by Lovell and Ogilvie. Instruction was in a mode compatible with the majority of elementary…
