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…

A sample of 43 second grade pupils was divided into groups which performed classificatory tasks with value labels, attribute labels, or a combination of these. Results showed that the value labeling improved the students' classificatory skills and increased the students' ability to generalize classificatory skill on far transfer tests. (MLH)

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…
