초록

의식적 자각은 우리의 시각 경험의 중요한 부분을 차지한다. 그러나 시지각에 있어서 의식의 역할과 중요성에 대한 질문들은 의식적 시각 경험이 지니는 주관적인 성격 때문에 오랫동안 심리학자들과 신경과학자들에 의해 연구되지 않은 채로 남겨져 있었다. 하지만, 최근 수십여 년 간 시각 연구 분야에서 의식, 특히 의식적 시자각에 대한 경험적인 접근들이 폭발적으로 증가하며 많은 주목을 받기 시작하였다. 본 저자는 이러한 경험적인 접근을 가능하게 한 정신물리학의 대표적인 실험 방법들-물리적 자극과 의식적 경험을 분리 가능하게 하는 현상들 -을 정리, 그 특징들을 소개하고 이를 상호 비교하는 리뷰 논문을 발표한 바 있다. 본 논문은 이러한 선행 연구의 이론적 배경을 다루고자 하였다. 구체적으로 본 논문은 시각에서의 의식에 대한 신경심리학의 이론들과 이 이론들이 제안하는 의식의 신경 기제에 관해서 논의한다. 또한 의식적 시자각의 신경 기제를 밝히는 데 있어서 중요한 도전이 되고 있는 주의와 의식에 대한 혼돈에 대해서도 논의한다. 시각에서의 의식에 대한 이론들과 연관 개념들에 대한 검토는 우리가 의식적 시자각에 대한 경험적 연구들을 올바르게 이해하고 수행하는 데 도움을 줄 수 있을 것이다.

Abstract

Conscious awareness occupies the central focus of our visual experiences. Nevertheless, questions on the role and the importance of consciousness in visual perception had long been neglected by psychologists and neuroscientists, mainly due to the subjective nature of conscious visual experiences. However, the last several decades have witnessed a burgeoning of empirical approaches to the study of conscious visual awareness. The current work is theoretical background behind the previous review on psychophysical conditions to manipulate conscious visual awareness. This work reviews theories of visual awareness and its neural correlates. It also discusses the confusion between attention and awareness which remains a major challenge for research on the neural correlates of conscious visual awareness. This review will set the scope within which empirical studies of conscious visual awareness will be understood and performed.
