Abstract

The purpose of present study was to examine whether the perceived distance is compressed to different extent according to the length of the tool in the object that is not reachable even when using the tool, and whether the perceived distance is compressed according to the tool length only in the object being pointed. In Experiment 1, we found by measuring the egocentric distance that the length of the tool causes the distance to the target to be closer to that of the object placed at a far distance. In Experiment 2, we found by measuring the egocentric distance that when the operated object and the non-operated object coexisted in the visual field, the length of the tool does not affect the distance perception to the non-pointed object. In Experiment 3, we found that the tool length affects only the distance perception of the operated object by measuring the exocentric distance which is the distance between the operated object and the target in the same environment as Experiment 2. The results of present experiment suggest that the compression of the perceived distance occurs at a distance that can not be reached by using the tool, and that the compression of the perceived distance is limited to the pointed object.

본 연구의 목적은 도구를 사용하더라도 닿지 않는 거리에 놓인 대상에서 도구 길이에 따라 지각된 거리가 상이한 정도로 압축되는지, 그리고 가리키는 대상에서만 도구 길이에 따라 지각된 거리가 압축되는지를 검증하는 것이다. 자기중심적 거리를 측정한 실험 1은 도구를 사용하여 닿지 않는 거리에 놓인 대상에서도 도구 길이가 길어질수록 대상까지의 거리를 더 가깝게 지각한다는 것을 발견하였다. 자기중심적 거리를 측정한 실험 2는 가리키는 대상과 가리키지 않는 대상이 시야에 공존할 때 도구 길이가 가리키지 않는 대상까지의 거리 지각에 영향을 미치지 않는다는 것을 발견하였다. 실험 3은 실험 2와 동일한 환경에서 표적과 측정 대상 사이의 거리인 대상중심적 거리를 측정하여 도구 길이가 표적의 거리지각에만 영향을 미친다는 것을 발견하였다. 이와 같은 실험 결과는 도구를 사용하여 닿을 수 없는 거리에서도 지각된 거리의 압축 현상이 나타나며 이와 같은 지각된 거리의 압축 현상은 가리키는 대상에 국한된다는 것을 시사한다.
