넛지 디자인 유형이 쓰레기 분리배출 행동에 미치는 영향 비교 연구 : 정보인지와 행동실행을 중심으로

초록

As environmental problems intensify worldwide, waste separation has become a key task for sustainable development, yet public participation remains low due to limited awareness, weak motivation, and operational complexity. Grounded in nudge design theory, this study examines how visual communication design can serve not only as an information tool but also as a medium for shaping public awareness and guiding social behavior. Foot-step design was classified into six nudge types, and a survey of 300 urban residents with waste-separation experience was analyzed using descriptive statistics, correlation analysis, regression, and SEM. The results show that environmental-structural and feedback nudges most effectively enhanced cognitive clarity and behavioral compliance, while emotional/interest-based nudges consistently strengthened participation motivation. Default-option and information-notification nudges improved sorting accuracy by reducing cognitive load and increasing identification efficiency. Overall, contextualized and combined nudge designs were more effective than single-type nudges, highlighting the need to better link case applications with public social contribution and visual evidence.
