This study is an examination of relationships between Myers-Briggs personality type preferences, based on Jungian theory, and communication apprehension. Results showed that participants who preferred introversion or sensing reported significantly higher levels of communication apprehension in general and across the group, dyadic, meeting, and public contexts than did participants who preferred extraversion or intuition. In addition, participants who preferred feeling reported higher levels of communication anxiety in the public context than those who preferred thinking. Findings support the assumption that communication apprehension is biologically based, suggest that the Myers-Briggs type preference framework offers an alternative way of understanding communication apprehension, and point out the need for new approaches to understanding the phenomenon of communication apprehension.
