This study of the effects of practice on children's perceptual judgments investigates the validity of the distinctive features hypothesis and the schemata hypothesis by comparing performance on discrimination tasks using familiar stimuli (letters of the alphabet) with a variety of transformations held constant over four massed practice conditions.…

This study reports the development of a sentence preference test designed to contrast tendencies to abstract, generalise and particularise in thinking. (Editor)

The task consisted of categorizing a set of slides depicting concepts of freedom, nonfreedom, justice, and nonjustice. The results of the analysis indicated that abstract thinkers performed significantly better than did concrete thinkers and that performance increased as a function of grade level. (Author/BJG)

This study examines the relative contributions of rote-memorization, analogic formation and rule-operation in the production of plurals. Rule-operation was found to be important in that children producing responses characteristic of a given stage did not produce responses for later stages. Contributions of analogic formation and rote-memorization…

Forty-eight kindergarten children were divided into four groups on the basis of their status (preoperational vs. transitional) and whether or not they received inversion-negation training. Results indicated no differences due to status, but differences due to training. Results do not confirm the contention that acceleration can only occur during…

Paper presented at the International Seminar on Experimental Research in Music Education (University of Reading, Reading, England, July 9-16, 1968).

Research based on author's doctoral dissertation, submitted to the Graduate School of the University of California at Los Angeles.

Children's use of proforms in spoken descriptions of real situations was studied and compared with that of adults to explore possible developmental progressions in the use of indexical reference. A discourse distinction between situational and textual reference was applied to data from 6-year-old and 10-year-old children and from adults. Subjects…

This study had two major purposes: to examine the effects of dimensional salience upon the learning of conjunction and disjunction rules, and to investigate an alternative to the prevailing cognitive-change accounts of developmental differences in multidimensional problem solving. The relative salience of each of four stimulus dimensions (form,…

THE PURPOSE OF THE STUDY WAS TO EXPLORE THE PIAGET CONCEPT OF CONSERVATION WITH REGARD TO THE CHILD'S CONCEPT OF THE PROPERTY OF LIQUIDS. AN INVESTIGATOR-CONSTRUCTED CONSERVATION INVENTORY WAS GIVEN TO 45 KINDERGARTEN AND FIRST GRADE PUPILS SELECTED FROM THE PRAIRIE ELEMENTARY SCHOOLS, URBANA, ILLINOIS, TO PROVIDE AN INDEX OF THE CHILD'S…

THE STUDY ASCERTAINED WHETHER VARIOUS TRAINING PROCEDURES CAN INFLUENCE THE ACQUISITION OF THE "PIAGETIAN" CONCEPT OF CONSERVATION OF SUBSTANCE. EQUAL NUMBERS OF MALE AND FEMALE, CAUCASIAN, KINDERGARTEN CHILDREN WERE RANDOMLY ASSIGNED TO FOUR EXPERIMENTAL AND TWO CONTROL GROUPS. THE TRAINING CONDITIONS WERE COGNITIVE CONFLICT, LANGUAGE…

While a critic measures a speech against a number of standards to determine its worth, a historian attempts to explain it in the context of social-institutional activity. After discussing the differences between rhetorical criticism and rhetorical history, this paper distinguishes among various types of historical explanations, illustrates each…

Two experiments were designed to assess children's ability to understand recursive structures of thinking which include thinking about contiguous people, thinking about action between people, thinking about thinking, and thinking about thinking about thinking. In Experiment I, 32 second, fourth, sixth, and eighth graders were tested on eight tasks…

Three units of instruction were given to 20 four-year-old children and 34 five-year-old children. Unit I was designed to develop the children's ability to establish a length relation between curved lines; Unit II, to develop ability to conserve length; and Unit III, to develop ability to conserve length relations. Testing of the children occurred…

Theories and practices concerned with cognitive functioning and development and its possible relationship to reading and reading instruction are reviewed. The nature of the strategies involved in reading and thinking are similar. Increase in task complexity for reading most likely involves cognitive functioning that ranges in complexity similar to…
