Mp. Etgen et Ef. Rosen, COGNITIVE-DISSONANCE - PHYSIOLOGICAL AROUSAL IN THE PERFORMANCE EXPECTANCY PARADIGM, Bulletin of the Psychonomic Society, 31(3), 1993, pp. 229-231
The physiological correlates of dissonance were investigated using a r
eplication of Aronson and Carlsmith's (1962) performance expectancy pa
radigm. Dissonance was predicted to be associated with an increased he
art rate and skin conductance response (SCR). This prediction was part
ially supported; dissonance was significantly related to heart rate ch
anges, but not to SCR. The results are discussed in terms of their imp
lications for the performance expectancy paradigm and its relationship
to dissonance and arousal.
