“…The energizing properties of dissonance arousal have also been shown on reduction of dissonance (for reviews, see Fazio & Cooper, 1983). For example, if arousal is increased by caffeine (Steele, Southwick, & Critchlow, 1981), or a sports session (Fazio & Martin, 1981, cited by Fazio & Cooper, 1983), attitude change increases. By contrast, if dissonance arousal is lessened by alcohol (Steele et al, 1981) or by a tranquilizing drug (Cooper et al, 1978), attitude change is lessened, too.…”
