이 연구의 목적은 '길 안내' 와 같은 문제해결 과정을 통해 나타나는 학생들의 공간적 문제해결 전략 및 개인차를 밝히는 것이다. 방문객의 길 안내를 위해 학생들이 캠퍼스에 세운 간이 표지판의 위치를 분석하였다. 학생들은 표지판의 위치로 급격한 방향 전환이 필요한 갈림길이나 길 안내의 출발, 도착지점을 선호하였으며, 경로를 선정할 때 효율성, 환경적 특성, 방문객의 심미적 만족감 등 다양한 요인들을 고려하였다. 또한 대부분의 학생들이 방문객의 예상 이동 경로를 따라 일렬로 간이 표지판을 세운 반면, 몇몇 학생들은 복수의 경로를 설정하는 전략을 사용하였다. 한편 동일한 과제를 실내에서 수행하게 했을 때, 실내에서 수행된 과제의 표지판들이 실외의 경우보다 균등한 간격으로 분포하는 특징을 보였다.
This study aims to reveal path selection strategies and individual differences in a navigation task. Two experiments were presented that studied human route planning performance as well as the cognitive strategies and processes involved. For the outdoor task, university students were asked to select a route based on the instruction, i.e. to find the best route from the campus main gate to the Education Building for conference visitors by locating eight signposts. Results indicate (1) that locations of signposts were selected preferably at decision points where the traveler needs to make a choice and starting/ending points of the navigation task and (2) a variety of route planning strategies considering efficiency goal (e.g., the shortest path), environmental characteristics (e.g., fewest turns), and aesthetic purpose (e.g., most scenic) were used. It is notable that some participants took into account more than one path by locating one or two signposts on an alternative route while others preferred a linear route connecting signposts between the start point and the destination. Prior to the main experiment, the same participants were asked to complete the same task inside the classroom to investigate changes in strategies between two tasks. Participants often tend to place signposts at more regular intervals for the indoor navigation task than the same task conducted outside.
