Preference scores were determined for several different groups of students ranging in age from seven to adult. In addition, instruments were administered to determine the cognitive level at which the students were capable of functioning. Comparisons between the students' cognitive level and preferences were made. The results indicated that the…

Combinatorial and implicative operations were studied with tasks which eliminated many complexities found in Piagetian tasks, but which did not alter the logical strategies required by Piaget's task. Task difficulty in relation to information-processing demands of tasks and processing capacities of subjects at three age levels (8.0-10.1 and…

The generalization of acquired competencies, specifically flexibility of closure, was the subject of this research. Flexibility of closure was defined as the ability to demonstrate selective attention to a specified set of elements when presented within various settings (the larger the number of settings from which the desired set of elements can…

The study relates performance on a cognitive-style measure of perceptual sensitivity and grade point averages to several indices of creativity as affected by a checklist procedure and verbal pretraining. Subjects were 76 students, half of which received verbal pretraining requiring them to list adjectives under five categories. The pretrained…

The purpose of this experiment was to provide further information on how an individual's strategy and his performance are affected by increasing the amount of relevant or irrelevant information he receives. The subjects were sixty volunteers from an undergraduate course in educational psychology who were randomly assigned to one of six treatment…

The nine problems used in the study of problem-solving processes are provided, along with the corresponding questions and their answers. Data on the values corresponding to each group, used in scoring, are also attached. (For related document, see TM 003 093.) (KM)

A theory that there is a correspondence between Piagetian conservation operations and groups of symmetry transformations, and that these symmetry transformations may be used in explaining human problem solving behaviors, is developed in this paper. Current research in artificial intelligence is briefly reviewed, then details of the symmetry…

This paper discusses the nature of natural and social sciences in order to point out the need for adapting standard logic more appropriately to a design approach. The IDEALS CONCEPT, an acronym for Ideal Design for Effective and Logical Systems, is presented as a move toward a calculus of design methodology with an emphasis on problem orientation…

An information-theory model of human memory was tested in thirteen experiments which involved children (six years and older) and graduate students. The subjects conducted science investigations in laboratory and non-laboratory settings, solved problems of electrical circuits, and participated in classroom science lessons. The tasks used involved…

A probabilistic model (see SE 013 578) describing information processing during the cognitive tasks of recall and problem solving was tested, refined, and developed by testing graduate students on a number of tasks which combined oral, written, and overt "input" and "output" modes in several ways. In a verbal chain one subject…

Seventy-two Ss attempted to solve four "who-done-it" type deductive reasoning problems which varied in mode of representation, type of logical connective employed, and affirmative versus negative statement of information. Affirmative and conjunctive problems were solved more frequently than negative and disjunctive problems (all are defined in the…

The study concerned (1) identifying component processes of discovery and rule learning; (2) describing differences in learning outcomes produced by the two instructional methods, and; (3) optimizing learning. It was believed that understanding the effects of aptitude, instructional methods, and their interaction is important in the study of…

CURRENT MODELS OF DECISION-MAKING AND RELATED RESEARCH IN CONNECTION WITH CERTAIN DEVELOPMENTAL TASKS OF ADOLESCENTS WERE REVIEWED. THE DECISION ELEMENTS RECEIVING THEORETICAL ATTENTION WERE (1) DECISION-PROCESS PHASES, (2) DECISION-OUTCOME PROBABILITIES AND STRUCTURAL COMPONENTS, (3) DECISION-PLAN DIMENSIONS, (4) DECISION STRATEGIES, AND (5)…

The relationship between the development of reversible thought and performance in arithmetic equations among children was investigated. Subjects were 86 second grade boys and girls. Two reversibility tasks and 20 addition and subtraction equations were administered. Results indicated significant correlations between the two variables only among…

Examines a study that suggests that quantification, defined as numerical data, increases textual difficulty and thereby discourages resolving scientific problems through public action. (MH)
