Document Summary
According to the elaboration likelihood model, we reserve elaborative reasoning for messages that seem most to us. A person on a diet who eats a piece of chocolate cake for lunch may experience related to this discrepancy between attitudes and behaviour. Insufficient justification effect: when a person relieves cognitive dissonance by changing their attitude (occurs only if the person has no easy way to justify the behaviour, given their attitude) For insufficient-justification, people must perceive their action as their own choice: ex. Students were asked to write essays supporting a bill that most opposed. Do attitudes predict behaviour: early research failed to find reliable correlations between attitudes and actions, ex. Student assessment of attitudes toward cheating: when asked to grade their own true-false tests, many students cheated, no correlation between attitudes and cheating, but, there are many situations in which attitudes do predict behaviour.
