| Abstract: | Research reported here replicates Greene and Sparks (1983a, 1983b) and their re-conceptualization of communication apprehension (CA). Noting the limited empirical evidence in support of a trait/structure link with physiological output, this study applies action assembly theory to the problem. Differential heart rate curves are predicted for high and low trait CA based on Greene's (1984) action assembly theory. The study confirms a hypothesized cubic heart rate function for low trait CA subjects and a quadratic heart rate function for high trait CA subjects. Results are interpreted as empirical support for an action assembly approach to communication anxiety. |
