The paper presents a model of interaction of basic mechanisms of interpersonal tolerance which the author describes as emotional cognitive dissonance, self-determination and coping. The author introduces the notion of "emotional cognitive dissonance" and argues its usefulness with reference to the problem of tolerance mechanisms. A model of reinforced motivation explains manifestations of genuine interpersonal tolerance as different from pseudo-tolerance or intolerance which are characterized by dominance of unconscious motivation and by "partial" motivation rather than a whole system of motives.
