Three studies were conducted with three groups of eighteen autistic children (3-11 years old) matched by age and IQ to developmental aphasic Ss to examine the nature of the cognitive deficit underlying autism. Two experiments were concerned with language comprehension using real and anomalous sentences, while the third investigation was an…

The nature of young children's inaccuracy in predicting their own memory performance was studied using categorical and unrelated material. Twenty-four children at each of four grade levels (kindergarten and grades two, four, and six) were presented with 18 cards bearing pictures of concrete nouns. Categorical pictures were presented on the right…

Potential differences in the learning abilities of adults and children, how they affect learning, and how to maximize adult education effectiveness are explored. The discussion of the differences and changes in the ability to learn covers such changes as those of physical attributes and mental abilities, as well as the role of both the…

THE PURPOSE OF THIS STUDY WAS TO FIND OUT WHETHER SOCIAL CLASS DIFFERENCES IN INTELLECTUAL DEVELOPMENT ARE PRESENT IF (1) CHILDREN FROM SOCIALLY DISORGANIZED SLUM FAMILIES ARE COMPARED WITH CHILDREN FROM STABLE, LOW INCOME AND MIDDLE INCOME FAMILIES, (2) THE PIAGET OBJECT SCALE, A NEW MEASURE OF COGNITIVE DEVELOPMENT BASED ON PIAGET'S SENSORIMOTOR…

The behaviorist and cognitive views of learning and language are contrasted, and some methodologies derived from the opposing positions are described. Programed reading in the form of machines, kits, and self-servicing devices of all sorts and most basal reader programs are identified as products of the behaviorist theory of reading instruction.…

Two Biological Sciences Curriculum Study (BSCS) approaches to teaching high school biology were employed to study the relative effects which different curriculum approaches might have on certain intellectual aptitudes of students. Subjects included 144 students enrolled in the BSCS Yellow Version and 143 students enrolled in BSCS Blue Version.…

With increasing subject matter specialization in secondary and elementary schools (particularly in mathematics and the sciences), it is necessary to include curriculum and course objectives related to the affective domain (social values) as well as those related to the cognitive domain. Subject matter is made meaningful to a student when related…

This is the report of a teaching experiment designed to teach the concept of equality as an equivalence relation to a group of first graders. The rationale, design, selected samples of the instructional materials, summaries of students' performances during the instructional program, analyses of students' performances on a series of evaluations…

Children's understanding of mathematical concepts, written symbolization of these concepts, and a specifically defined readiness factor were investigated. Thirty-eight first graders were classified as ready or not ready according to scores on a readiness test. Students were paired, with 11 pairs of not-ready and 8 pairs of ready students; one…

This report presents the results of a teaching experiment which investigated (1) the role of mathematical experiences on the development of counting, addition, subtraction, mental arithmetic, classification, and other arithmetical topics and (2) the role of quantitative comparisons and class inclusion as readiness variables for learning the…

An exploratory investigation designed to gain insights into children's mathematical formulation of observed actions upon objects is presented. Eight episodes in which first and second graders were asked to interpret, in terms of number sentences, a sequence of actions with unifix cubes are also presented. Results of analysis of the videotaped…

This study examined the ability of preschool children to process and use conceptual category information in a disrcimination learning task. A total of 60 boys and girls between the ages of 2 1/2 and 4 years completed a 3-choice discrimination learning task. On each of 12 trials, a child was presented with three magazine photographs: one of an…

The purpose of this study was to investigate the relationship between 64 six- and seven-year-old children's perception of the reality of television and the Piagetian construct of cognitive development. The children were asked to view two television episodes (a highly similar, closely matched pair from the television series "Star Trek")…

Presented is a brief review of major writings on cognition in the field of deaf education, in which the main cognitive-developmental theories are identifed. Within this framework is discussed deaf children's mental development in terms of apparent characteristics and empirical evidences of cognitive behaviors compared with those of children with…

This study investigates the reliability and construct validity of a group administered test of Piaget's formal operations stage. A related problem involving a learning effect associated with Piaget's clinical methods is also investigated. The Piagetian Logical Operations Test (PLOT), a group-administered instrument, was developed and field-tested.…
