A two-factorial experiment investigated the importance of emotional consequences of distributive injustice. We manipulated payment inequity (disadvantageously inequitable, advantageously inequitable, equitable) between a subject and a confederate. At the same time, by means of fictitious ion concentration with assumed arousing, relaxing or emotionally irrelevant side effects we manipulated misattributions of arousal. In accordance with equity theory (WALSTER, WALSTER & BERSCHEID, 1978) and two factor theory of emotion (SCHACHTER, 1964) we found, that Ss who were led to believe in arousing side effects of ion concentration were less motivated to restore equity than Ss in the irrelevant symptoms control group. On the other side, Ss who were led to believe in relaxing side effects showed intensified motivation to restore equity to their relationship with the confederate. Results support the assumption that inequity distress is a necessary, although not a sufficient condition for reactions aimed at the restoration of equity. Finally, consequences of the results for future research in the field of distributive injustice are discussed.
