| Abstract: | The study of communication apprehension (CA) impact in the instructional environment is extended through examination of all three CA levels relative to various performance situations in a basic communication course. Results indicate significant differences in achievement indices between all three CA groups on final course grade and the first two of four performance assignments. Moderate and high CA groups were not significantly different from each other on the third and fourth performance tasks. Low and high CA groups were significantly different in all performance areas. No differences were indicated between CA groups on the final examination. Results are discussed relative to the naturalistic nature of the study. |
