In one of Festinger's experiments, participants performed a long and boring task, but after the experiment they said the task was interesting. When they received only a small reward for this "lie", they actually found the task more interesting than when they did it for a normal payment. How does cognitive dissonance reduction theory account for this behaviour?

Question restatement: In Festinger’s experiment, participants did a long, boring task and then claimed it was interesting. With only a small reward, they reported greater interest than those given a normal payment. How does cognitive dissonance reduction theory explain this behavior?

Option 1: By observing the behaviour of others, participants concluded that the task was interesting.
This option attributes attitude change to social comparison or observational learning from others, not to the internal tension between behavior and attitude that cognitive dissonance emphasizes. The key mechanism in Festinger’s theory is not about external observers but about the individual’s own internal inconsistency, so this explanation misses the dissonance aspect.

Option 2: Participants experienced tension because of the discrepancy between their behaviour and their attitudes, so they changed their attitudes towards the task.
This aligns with cognitive dissonance theory. When the reward is small, there is insufficient external justification for lying about enjoying the task, creating dissonance between the unliked, dull activity and the reported interest. To reduce this discomfort, people may adjust their internal attitude to be more positive about the task, explaining why they later rate it as more interesting.

Option 3: Participants believed that if they received little reward, the behaviour was due to the circumstances, and if they received a lot of reward, the task was the focus of attention.
This mixes up causal explanations in a way that resembles external attribution or the overjustification effect but does not capture the specific dissonance-resolution process. It suggests a conditional reasoning about causality that doesn’t map cleanly onto the observed pattern of attitude change under minimal external justification.

Option 4: Participants concluded that the task was interesting by observing their own behaviour.
This describes a form of self-perception theory, where people infer attitudes from their own actions in the absence of strong prior attitudes. While related to attitude formation, it is not the cognitive dissonance mechanism at work in Festinger’s experiment, which emphasizes resolving inconsistency between behavior and attitude rather than inferring attitude from behavior.
