Abstract

Changes in visual sensitivity were investigated as a function of distance from the locus of attention. While a subject was fixating at a point on a frontal plane, one of the two attention inducing points placed horizontally and symmetrically 4。 apart from it was blinked and a target immediately followed at a location around the blinking dot. The subject's task was to decide and report whether the target was present or abscent. The rate of detection was the highest at the immediate vicinity of the locus of attention and decreased gradually as a function of the distance from it. Results of the experiments support the gradient model of attention-induced changes in visual sensitivity.

주의 위치로부터의 거리에 따른 시각 민감도 변화를 조사하였다. 피험자가 시야 평면의 한 점을 응시하는 동안 응시점에서 좌우 대칭으로 4。 떨어져 있는 주의 유도점중 하나를 깜빡인 다음 주의 유도점 부근에 표적 자극을 제시하였다. 피험자의 과제는 그 표적이 나타났는지의 여부를 판단하여 보고하는 것이었다. 표적 자극의 탐지율은 주의 유도점 인접한 곳에서 가장 높았으며 그곳으로부터 멀어질수록 점진적으로 감소하였다. 이러한 결과는 주의 유도에 의한 시각 민감도의 점진적 변화 모형(gradient model)을 지지하는 것이다.
