The size of focused attention was assessed within a three-dimensional display. Subjects viewed random-dot stereogram displays in which they responded differentially to vertical and horizontal bars. Adjacent noise elements either were identical to the response target or specified the opposite response. The position of the noise elements was varied in depth according to binocular disparity. Interference by incompatible noise elements decreased with depth separation between the noise elements and response target. In addition, interference was greater for noise elements that were more distant from the observer than from the response target than it was for noise elements that were closer to the observer than to the response target. The implications of these results for a viewer-centered representation of focused attention in depth are discussed.
在三维显示中评估了聚焦注意力的大小。受试者观看随机点立体图显示，在其中他们对垂直和水平条做出不同反应。相邻的噪声元素要么与反应目标相同，要么指定相反的反应。噪声元素的位置根据双眼视差在深度上变化。不兼容噪声元素的干扰随着噪声元素与反应目标之间的深度分离而降低。此外，对于离观察者比离反应目标更远的噪声元素，其干扰大于离观察者比离反应目标更近的噪声元素。讨论了这些结果对于以观察者为中心的深度聚焦注意力表示的意义。
