본 연구는 사람들이 사소한 교통법규를 어기는 행동을 한 후에 법규를 준수해야 한다는 일반적인 태도와 위반행동 사이에서 인지부조화를 경험하며, 그 부조화를 경감시키기 위해 법규 준수에 대한 자신의 태도를 부정적으로 변화시킬 가능성을 확인하였다. 이를 위해 교통법규 위반 행동(무단횡단, 불법주차, 신호위반)을 묘사하는 시나리오를 읽고, 그 위반행동에 대해 지지하는 글을 쓰게 하여 인지부조화를 경험하게 한 실험참가자들에게서 태도변화가 일어나는지를 관련 교통법규준수 태도를 반복 측정하는 피험자 내 설계를 통해 조사하였다. 실험결과에 따르면, 부조화 처치 전과 후의 일반적인 교통법규준수 태도를 비교한 결과, 전보다 후에 태도가 더 부정적으로 변화하였으며, 시나리오로 제시된 각 교통법규 위반상황과 관련된 태도문항들에서도 부조화를 경험하기 전보다 후의 각각의 교통법규 준수태도가 더 부정적으로 변하였다. 더 나아가 태도변화에서 인지부조화의 역할을 확인하기 위한 추가분석에서, 시나리오로 제시되지 않은 교통법규와 관련된 태도문항들(인지부조화와 관련 없는 문항들)에서는 반복측정 간에 유의미한 차이가 없었으며, 3개의 시나리오 중에 더 많은 시나리오의 위반행동에 대해 지지하는 글을 쓸수록 태도가 더 부정적으로 변화하는 패턴을 확인할 수 있었다. 또한, 각 시나리오의 위반행동에 대해 지지하는 글을 작성한 집단이 그렇지 않은 집단보다 태도가 더 부정적으로 변화하였고, 초기의 교통법규준수에 대해 긍정적인 태도를 가진 실험참가자가 더 많은 태도 변화를 보였다. 이러한 결과들은 결론적으로 사소한 법규위반행동이 법규에 대한 부정적 태도를 유도하고, 그 과정에서 인지부조화 기제가 중요한 역할을 한다는 사실을 지지한다. 규범-행동 간의 부조화에 의한 태도변화 가능성을 인지/대리 부조화적 설명과 함께 비교문화적 관점에서 논의하였다.
The present research examined the proposition that once people violate traffic regulations, they would experience cognitive dissonance and subsequently engage in changing their attitudes toward the law negatively in order to reduce the dissonance. In an experiment, participants were presented with three scenarios in which a person violated trivial traffic laws, and they were asked to imagine themselves as the person of the scenarios and write statements supporting the unlawful behaviors. Participants' attitudes toward the general traffic law and the regulations related to the violations were measured 8 weeks before and right after the experimental treatment. The results, as expected, showed that their attitudes toward the general traffic law and the specific regulations in the scenarios changed negatively after writing the statements. In each scenarios, the participants who chose to wrote statements supporting the unlawful behaviors showed great attitude changes that those who did not write the statements. Furthermore, attitudes toward the regulations that were not directly related to the scenarios did not change significantly, and participants who were expected to experience stronger dissonance arousal (e.g.., supported more unlawful behaviors or had have more positive attitudes toward the law before the experiment) showed greater attitude changes. These results support the effects of trivial unlawful behaviors on attitudes toward the law and strongly suggest the role of cognitive dissonance underlying the effects.
