dc.description.abstractAlthough consumer response is commonly determined by means of product characterization in the field of sensory science, there is still a lack of research on the perceptual dimensions with which the product characteristics itself are being assessed. For more effective study on the relationship between product stimulus and human perception, the utilization of ‘double-faced applicability’ (DFA) test using three-dimensional perception model was proposed. As another approach to examine consumer response to stimulus, emotion circumplex model was applied in contrast as it not only involves the “pleasant” and “unpleasant” emotions which are comparable to semantic-differential questions (high-end and low-end descriptors) of DFA test but also to better understand product-consumer relations in terms of its emotional associations. Hence the objective of this study was to compare DFA test using three-dimensional perception model and emotion circumplex model in relation to its product characterization, discriminations and consumer overall satisfaction. The effects of measuring consumer overall satisfaction concurrently with the sensory and emotional characteristics of products as well as general associations between sensory and emotional attributes were also investigated. Using between-group and within-group designs, a total of 224 females ranging from 19-39 years old were randomly divided into Group 1 and Group 2 to evaluate eighteen milk-containing Ready-To-Drink coffee products. Group 1 was provided satisfaction test, DFA test and emotion circumplex model while Group 2 was provided only satisfaction test and emotion circumplex model. The results of product characterization obtained from ‘double-faced applicability' test using a three-dimensional perception model were similar to that from emotion circumplex model. Emotional associations to integrated perceptual model illustrated that the high-end and low-end integrated sensory descriptors were well-correlated to “pleasant” and “unpleasant” emotions. Such observation can be further explained by the significant positive relation to increasing consumer overall satisfaction, revealing the qualities that were able to predict overall satisfaction. Hence it signified that DFA test using integrated perception model could be an efficient method to study product qualities.;감각 과학 분야에서 제품에 대한 소비자의 반응은 일반적으로 제품 특성화를 통해 조사하지만 제품 특성이 평가되는 지각 차원에 대한 연구가 부족하다. 자극과 인간 인식의 관계에 대한 보다 효과적인 연구하기 위해 2단계 평점 기반 ‘양면 적용성’ 평가법에 (two-step rating-based ‘double-faced applicability’ test) 이용한 3차원 인식 모델이 제안한다. 게다가 제품 자극에 대한 소비자의 반응을 살펴보는 평가법 중 하나인 emotion circumplex 모델에 포함된 “pleasant”와 “unpleasant” 감성이 ‘양면 적용성’ 평가법의 긍정적 특성과 부정적 특성과 비교할 수 있을 뿐만 아니라 감정적 연관성으로 제품과 소비자의 관계를 이해할 수 있다. 따라서 본 연구의 목적은 제품 특성화, 제품 차별화 및 소비자의 전반적인 만족도로 3차원 인식 모델을 이용한 ‘양면 적용성’ 평가법을 emotion circumplex 모델과 비교하고자 하였다. 또한 소비자 만족도와 통합적 감각 특성을 활용한 ‘양면 적용성’ 평가법을 함께 평가했을 때, 제품의 특성 평가가 제품에 대한 소비자의 만족도에 미치는 영향을 알아보고자 하였다. 마지막으로 감각과 감성의 관계를 고려하여 소비자 만족도에 영향을 주는 주요 특성을 조사하고자 하였다. 총 224명의 만19~39세 여성을 모집하여, 그룹 1에 112명, 그룹 2에 112명으로 무작위로 나누었다. 우유가 함유된 Ready-To-Drink 커피 제품 18가지에 대해, 그룹 1은 만족도 평가, ‘양면 적용성’ 평가 및 emotion circumplex평가를, 그룹 2는 만족도 평가 및 emotion circumplex 평가를 진행하였다. 두개의 평가법을 within-group과 between-group으로 비교했을 때 ‘양면 적용성’ 평가와 emotion circumplex모델로 도출된 제품 특성화 패턴이 유사한 것으로 보였다. 3차원 통합 인식 모델에 대한 감정적 연관성을 통해 high-end와 low-end 감각적 특성이 "pleasant" 감정과 "unpleasant" 감정과 잘 연관되어 있음을 보였다. 또한 모든 통합적 감각 특성은 만족도와 양의 상관관계가 있으며 소비자의 만족도를 예측할 수 있는 주요 제품 특성을 확인하였다. 따라서 통합 인식 모델을 이용한 ‘양면 적용성’ 평가는 제품 품질을 효율적으로 연구할 수 있는 평가법에 대해 확인하였다.-
