마르셀 뒤샹이나 지아코모 발라와 같은 미래파 화가들은 물체가 움직이는 순간 순간의 정지 이미지를 캔버스에 중첩해서 운동감을 표현하려고 했다. 본 연구진은 선행 연구에서 이렇듯 운동성이 내포된 추상 미술 작품들에 대한 사전 경험이 뇌의 운동 지각 영역의 반응에 영향을 미친다는 것을 보고한 바 있다. 본 연구에서는 선행 연구에서 관찰된 사전 경험에 따른 차별적인 뇌 운동 지각 영역의 활성화가 안구 운동 패턴의 차별성에 기인하는지 살펴보았다. 사전 경험은 미술 전공 여부로 조작하였다. 또한 전문성 이외에도 움직임 내포에 관한 화가의 의도 자각 여부에 따라 관찰자의 안구 운동 패턴에 차이가 나타나는지 검증해보고자 하였다. 연구 결과, 미술 전공 여부에 따라 추상화 지각시 그림 전체에 대한 시선고정 횟수나 시간 등에 차별적인 경향이 나타났다. 화가의 표현 의도에 대한 자각은 이러한 전반적인 차이와 관련이 없었다. 반면, 운동성의 내포라는 화가의 표현 의도의 자각은 추상화 중 운동성이 표현된 특정 위치에 대한 안구운동과 연관성을 보였다. 즉, 표현의도를 자각한 관찰자들은 그렇지 못한 관찰자들에 비해 추상화 중 움직임과 연관된 신체 부위가 표현된 위치에 좀 더 집중하는 경향을 나타냈으며, 화폭에 표현된 물체의 움직임 방향과 합치하는 방향의 안구 운동을 더 많이 보였다. 미술 전공 여부는 움직임 표현 위치에 특정적인 안구 운동과 무관하였다. 이러한 결과는 미술 전문성 및 화가의 의도 자각 여부가 관찰자들이 움직임이 함축된 추상화를 지각하는 방식에 차별적으로 관여함을 시사한다. 즉, 전문성은 그림에 대한 전반적인 지각 방식에, 내포된 움직임에 대한 자각은 그 정보에 특정적인 공간에 대한 지각방식에 관여할 가능성을 제안한다.
Abstract
Artists such as Duchamp and Balla tried to portray moving objects on static canvases by superimposing snapshots of moving objects. Previously, our group showed the influence of prior experience on brain responses within a motion-sensitive area MT+ to abstr act paintings with or without implied motion. In the present study, we went further to investigate whether the differential MT+activation between observers is originated from differential eye movement patterns. Prior experience was defined operationally with major in art. In addition, we examined whether perceiver’s awareness of artist’s intention concerning the implied motion, as well as expertise in art, affects the way he/she views the artwork. Results showed that the number and the duration of fixation on the abstract paintings tended to differ between participants based on art major. The awareness of artist's intention was not related to such differences. In contrast, observers' awareness of artist's intention of implying motion affected eye movement patterns in specific regions of the abstract paintings where the motion was portrayed. In other words, observers with awareness focused more on the parts of paintings portraying motion and moved their eyes in the direction corresponding to the direction of moving objects than observers without awareness. Expertise was not related to such specific eye movement patterns. The present study implies that art expertise and awareness of artist's intention play differential roles in observers' perception of paintings with implied motion. Namely, it suggests that expertise is related to the overall perception of paintings, while awareness of implied motion is related to perception of the specific spatial information in those paintings.
