The theory of cognitive dissonance posits that when an individual 's cognitive elements are inconsistent with each other, a state of cognitive dissonance exists [15,

When an individual is confronted with cognitive dissonance, several modes may be used to restore consonance: inconsistency repression, bolstering, the "other" inconsistency, object modification, peer devaluation, selective exposure, and selective avoidance [27].

As in the case of cognitive dissonance, when a person perceives inequity in a social exchange relationship, a motivation develops to restore equity or balance. A person may use several possible methods for reducing inequity [1]:
1. Increase inputs if they are low in relation to outcomes and the inputs of appropriate referents.
2. Decrease inputs if they are high in relation to outcomes and the
