초록

선행 연구들에서는 그럴듯한 기준점이 극단적 기준점보다 더 큰 기준점 효과를 야기하는 반면, 주어진 문항과 관련된 개인의 지식수준이 높으면 기준점 효과가 작아진다고 보고하고 있다. 하지만 제시되는 기준점이 그럴듯한지 여부와 주어진 문항 자체의 난이도가 기준점 효과에 미치는 영향을 함께 살펴본 연구는 없었다. 따라서 본 연구에서는 기준점의 극단성과 문항의 난이도가 기준점 효과에 미치는 영향을 살펴보았으며, 이에 더해 응답 확신도와 기준점 효과의 관계도 살펴보았다. 이를 위하여 예비 연구를 통해 쉬운 문항과 어려운 문항, 그럴듯한 기준점과 극단적인 기준점을 선정하였다. 본 실험은 '표준 기준점 실험 절차' 에 따라 진행되었다. 연구 결과, 기준점의 극단성과 문항의 난이도는 각각 기준점 효과에 영향을 미쳤으며 문항의 난이도는 응답 확신도에도 또한 영향을 미쳤다. 구체적으로, 그럴듯한 기준점을 제시했을 때와 어려운 문항을 제시했을 때에 기준점 효과가 크게 나타났다. 또한 자신의 수행에 대한 확신이 낮을수록 극단적인 기준점이 제시되었을 때 기준점의 영향을 크게 받았다. 이러한 결과는 기준점이 그럴듯한지와 문항의 난이도에 따라 기준점 효과의 크기와 확신 정도, 그리고 기준점 효과와 확신도 사이의 상관관계가 다르게 나타난다는 것을 보여준다. 본 연구의 결과는 기준점의 특성이나 개인의 상태에 따라 기준점 효과가 달라진다고 제안하는 기준점 효과에 관한 태도 변화 관점을 뒷받침한다.

Previous studies have reported that a plausible reference point has a greater anchoring effect than an extreme reference point. It is also known that the anchoring effect decreases when the individual's level of knowledge related to a given item is high. However, there has been no study examining the interaction of the plausibility of the reference point and the difficulty of the given question. Therefore, in this study, the effect of the reference plausibility and the difficulty of the questions on the anchoring effect were examined. The relationship between the response confidence and the anchoring effect was also examined. To do so, easy and difficult questions, plausible and extreme reference points were selected through preliminary research. The experiment was conducted following the 'standard anchoring task procedure'. As results, the extremity of the reference point and the difficulty of the question affected the size of the anchoring effect respectively. The difficulty of the question also affected the confidence of the response. Specifically, when a plausible reference point was presented and when a difficult question was presented, the anchoring effects were increased. In addition, the lower the confidence in one's performances, the greater the influence of the reference point when an extreme reference point was presented. These results show that the plausibility of the given reference point and the difficulty of the item have different effects on the magnitude of the anchoring effect and the degree of confidence. The results of this study support the attitude change perspective regarding the anchoring effect, which suggests that the anchoring effect varies depending on the characteristics of the reference point and the individual's knowledge.
