Thirty hearing impaired students (11-14 years old) participated in a study to measure classification principles using demonstration or display of labels containing relevant words or iconic signs. Three methods of teaching classificatory principles were employed: demonstration, verbal labels, or iconic labels. Analysis of mistakes made by Ss…

The effect on concept learning of requiring the memorization of either examples or nonexamples prior to going through a theoretically effective training program was compared to the performance of groups of seventh and eighth graders who either memorized nothing or memorized subconcepts of the concept definition. Correct classification scores and…

Analyzes attributes of symbols and identifies the need for a suitable management system for retrieving images from a database. A classification structure that incorporates graphic, semantic, and bibliographic dimensions is described; experiments with describing, sorting, and drawing symbols are reviewed; and future work on a database management…

Forced-choice items, investigating the performance of 80 undergraduates on verbal classification and verbal analogy, were sequentially presented, allowing independent estimates of the accuracy of four principle component processes: inference, application, recognition, and distraction. Within-task performance showed substantial individual variation…

Naming tasks were used in two studies to test for conceptual organization in young children by comparing the latencies for naming objects in primed vs. non-primed conditions. In the primed condition, a taxonomic category was primed by prior activation of a coordinate member of the same category. In Study 1, 54 kindergarten children were randomly…
