Informational Components of Attribute Identification and Rule Learning Aspects of Conceptual Behavior

Two experiments were performed to discover the affect of equalization of positive and negative instances in the presentation of stimuli for Attribute Identification and Rule Learning problems. 56 student volunteers from CWSC were used as subjects. Stimuli were presented to them either according to the traditional truth table representation (four classes for every four trials) or by presenting an equal number of positive and negative instances. The results showed that tasks requiring identification of the relevant attributes among stimulus characteristics were performed better if the stimuli were equalized for positive and negative instances
