Explanation:  

Dissonance theory: In psychology, the term "dissonance theory" was introduced by Leon Festinger during 1957, and is defined as a process in which an individual experiences dissonance by holding contradictory values, beliefs, or ideas i.e, the way an individual thinks and the way he or she behaves is entirely different and because of this the person experiences "psychological stress or tension".

Self-perception theory: In psychology, the term "self-perception theory" was proposed by a psychologist named Daryl Bem, and is defined as a process of "attitude formation".
