A model for the analysis of simple human conceptual behavior, based on the apparent similarities of human conceptual behavior and that of infrahuman subjects, is developed. A minimum definition of conceptual behavior is given: A single response, verbal or nonverbal, under the discriminative control of a group of stimuli whose parameters are…

Three experiments tested the application to art of an hypothesis from the concept attainment literature, that conceptual learning is enhanced by providing multiple examples prior to test trials. Subjects were given discrimination tasks involving surrealistic and non-surrealistic paintings. The feature abstraction model proved inadequate in this…

One of the most important capacities which children employ when learning language is the capacity to generalize. A child who hears an utterance of a verbal expression while perceiving a particular object (or action, aspect, etc.) becomes normally able to apply the expression not only to this object but also to all those objects which, for him, are…

PIAGET HAS BEEN CONCERNED WITH THE ASSESSMENT OF THE PRESENCE OR ABSENCE OF CONSERVATION AND RELATED PROCESSES, BUT HE HAS NOT FOCUSED EXPERIMENTALLY ON THE FACTORS WHICH CAN ACCOUNT FOR THE LEARNING OF CONSERVATION. TO INVESTIGATE SUCH FACTORS, RESEARCH WAS CONDUCTED (1) TO DETERMINE THE RELATIVE EFFECTIVENESS OF TWO PARTICULAR GROUP TRAINING…

The occurrence of the two allomorphs of the indefinite article in standard English ("a" before nouns or noun clauses beginning with consonant sounds and "an" before those beginning with vowel sounds) is a concept similar to those studied in the general concept formation paradigm. The acquisition of this grammatical concept was examined using 80…

The purpose of this study was to empirically test a set of predictions implied by the Model of Conceptual Learning and Development using the concept of cutting tool. Four subtests were developed to assess a subject's ability to perform at each of four successive levels of concept attainment (concrete, identity, classificatory and formal). In…

The Model of Conceptual Learning and Development (CLD) is an analytical, descriptive model. It defines four levels of concept attainment and the possible uses and extensions of attained concepts, specifies the cognitive operations involved in learning concepts at each of the four levels, and postulates internal and external conditions of learning…

Piaget's model of children's conceptual learning and development was compared with Klausmeier's Conceptual Learning and Development (CLD) model in a longitudinal study. The CLD model suggests four successive levels of concept learning: (1) concrete--recognizing an object which has been encountered previously; (2) identity--recognizing a known…
