  • Cognitive Dissonance (Festinger, 1957)
    • When one or more cognitions are inconsistent with each other. For example 'I like psychology'  and 'I don't like going to psychology class'
    • Dissonance can be removed in a number of ways.
      • Changing one of the cognitions
      • Adding a cognition that explains the dissonant relationship
    • Key Study - Festinger and Carlsmith (1959)
      • How dissonance is created by counter-attitudinal behhaviour.
      • Individuals were asked to participate in a very boring task. Afterwards, they were asked to tell other participants what they thought of it.
        • Some were paid $1 and some were paid $20
          • Those who were paid $1 rated the experiment more interesting because the money wasn't sufficient justification for their actions. They had to change their attitude,.
    • Post Decisional Dissonance
      • The uneasy feeling prior to decision making where an individual feels as though they have made the wrong choice.
      • This dissonance can be overcome by selectively exposing yourself to positive information about the choice.
