본 연구는 뮬러-라이어 착시 도형을 이용하여 지각과 동작 수행 간에 나타나는 정보획득과정에 어떠한 차이가 있는지 살펴보고, 조준과제와 잡기과제에서 나타난 행동학적 특성을 통해 지각과 동작의 제어 특성을 밝히고자 하는 연구 목적에 부합하기 위하여 이러한 목적을 달성하기 위하여 대학생 15명을 연구 대상자로 선정하여 실험에 참여하도록 하였다. 지각판단 과제, 잡는 잡기 과제, 조준과제를 수행하였다. 실험을 위해서 안구 움직임 추적장치(EMR-9), 3차원 동작 분석 시스템을 사용하였다. 이러한 변인에 대한 지각과 동작 수행의 정보획득과정의 차이를 살펴보기 위하여 반복측정 일원분산분석을 실시하였다. 이와 같은 연구 방법 및 분석 결과를 토대로 얻어진 결론은 다음과 같다. 뮬러-라이어 착시 도형에서는 실제 크기와 다르게 지각 하였을 때 잡기 과제에서 다르게 지각한 것이 동작 수행에 영향을 끼쳤고, 최대그립크기와 같은 요인에서도 다르게 지각한 요인의 영향을 받은 것으로 나타났다. 이와 같은 결과로 부터 지각과 동작 제어 기전에서 연합성과 분리성의 개념이 아닌 복측흐름과 배측흐름에서 서로 상호작용이 발생한다고 볼 수 있다.
The objective of this study is to determine the mechanism of perception and motion control. For this, two experiments were performed under two research tasks. aims to examine the differences of the process of acquiring information between perception and motion performance by using Muller-Lyer Illusion, and to determine the characteristics of perception and motion control through behavioral characteristics shown from tasks of aiming and catching. In order to achieve the study objective, 15 university students participated in the experiment. Every subject performed the task of perception/judgement in which they see and perceive figures shown on the screen and then show the size of the disappeared figures with a thumb and index finger, the task of catching in which they should catch the figure on the screen with two fingers and the task of aiming in which they should move the end of the figure quickly. For the experiment, we used the wireless eye movement tracing equipment(EMR-9), 3D motion analysis system3(OPTPTRAC3020) and screen. In order to examine the differences of the process of acquiring information for perception and motion performance with such variables, the one-way ANOVA with repetition was conducted. The conclusion based on such study methods and analysis results is like below. When it was perceived differently from the actual size of Muller-Lyer illusion, first, different perception for the task of catching had influence on performing motion and a factor like the biggest grip size. This means that it is same as the theory that perception and motion coincide with each other. With the control figure, second, the size of the wing out figure was perceived as 2cm bigger in the task of perception/judgement while the sizes of the wing out and wing in figures were same in the task of catching. This means that the result is close to separativeness between perception and motion. Based on the results, the mechanism of perception and motion control has interactions in inferior temporal cortex and posterior parietal cortex, rather than the concept of association and separativeness.
