본 연구는 한 자극이 제자리에서 반복적으로 점멸하는 매우 단순한 자극 시퀀스에서 인접 위치에 큰 물체가 함께 제시될 때, 가현운동이 지각될 수 있는지를 알아보았다. 연구 결과, 점멸 자극과 인접 물체 간 경계에 중첩의 이미지 단서가 주어지고 자극 간 시간 간격이 길 때, 인접 물체 뒤로 숨었다가 나타나는 가현운동이 관찰되었다. 이 결과는 가려져서 보이지 않는 물체의 무형 표상이 움직임 대응 관계에 사용되어, 출현과 소멸(coming into/going out of existence)의 물리적 시퀀스가 드러남과 가려짐(coming into/going out of sight)의 가현운동으로 지각될 수 있음을 시사한다.
The current study investigated whether the display of a repeatedly blinking object in place can give rise to a percept of apparent motion, when it is accompanied by a large occluder object. The result shows that apparent motion of an object behind the occluder can be observed when image cues for occlusion are given and the temporal interval between stimulus onsets is large enough. This result suggests that apparent motion can generate the perception of occlusion so that a physical sequence of objects coming into and going out of existence turns to be perceived as coming into and going out of sight.
