ABSTRACT
The personality traits, extroversion (E)/introversion (I), are among the few that researchers agree provide consistent and valid information. In addition to describing and predicting social behavior, they also have been shown to predict learning and the ways that individuals process information. As the words imply, thinking and behavior that are directed inward or to oneself is known as introversion; the thinking and behavior that is directed outward, or to the surrounding environment, is extroversion. Some researchers and educators use the terms action-oriented for extroverts and reflective-oriented for introverts because the terms extroversion and introversion have negative connotations in some circles. Henjum (1982) described two types of introverts: Type-A introverts who are selfsufficient, hardworking, confident, and successful; and Type-B introverts who are shy, uncommunicative, withdrawn, and self-conscious.
