본 연구에서는 온라인 구매 환경에서 연구되는 개인차 요인 중 하나인 접촉욕구(Need-For-Touch: NFT) 수준과 환경적 요인인 상품의 이미지 제시방식이 상품에 대한 지불의사 가격(Willingness To Pay: WTP)에 미치는 영향을 살펴보았다. 또한 이미지 제시방식과 지불의사 가격의 관계를 심상선명도(Vividness of Mental Imagery: VMI)와 선택시간이 이중 매개함을 밝힘으로써 각 이미지 제시방식에 따른 지불의사 가격이 결정되는 과정을 살펴보았다. 실험 결과, 지불의사 가격은 이미지 제시방식, 접촉욕구 수준에 따른 상효작용 효과를 보였다. 접촉욕구가 높은 집단에서는 정적 이미지를 제시하였을 때 지불의사 가격이 높아짐을 알 수 있었고, 접촉욕구가 낮은 집단에서는 이미지 제시방식에 따른 지불의사 가격의 차이가 없음이 나타났다. 심상선명도와 선택시간의 이중매개효과를 살펴본 결과, ‘이미지 제시방식 → 심상선명도 → 선택시간 → 지불의사 가격’의 경로로 이미지 제시 방식과 지불의사 가격 사이를 매개 하였다. 즉, 정적 이미지의 경우 덜 생생한 심적 이미지(심상선명도)를 형성하고, 그에 따라 심사숙고 시간(선택시간)이 길어지면서 지불의사 가격이 증가하는 것으로 보인다.
In this study, the effects of Need for Touch(NFT) level, which is one of the individual difference factors studied in the online purchasing environment, and the image presentation method which is one of environmental factors on the willingness to pay(WTP) were examined. In addition, the process of determining the willingness to pay along with each image presentation method was examined by revealing the double mediation effect of the vividness of mental imagery(VMI) and decision time(DT) between the relationship of the image presentation method and the willingness to pay. As a result of the experiment, the willingness to pay showed an interaction effect depending on need for touch level. In the group with high level of need for touch, it was found that the willingness to pay was higher when the static image was presented. And in the group with low level of need for touch, it was found that there was no difference whether the static or the rotation image was presented. As a result of examining the dual mediation effect of vividness of mental imagery and decision time, the relationship between the image presentation method and the willingness to pay was mediated by the route of ‘image presentation method → vividness of mental imagery → decision time → willingness to pay’. That is, in the case of static image, the vividness of mental imagery is low and accordingly the willingness to pay is increased as the decision time becomes longer.
