集中注意力的大小在三维显示中进行评估。受试者观看随机点立体图显示，他们对垂直和水平条的反应不同。相邻的噪声元素要么与响应目标相同，要么指定相反的响应。噪声元素的位置根据双眼视差在深度上变化。干扰不兼容的噪声元素之间的深度分离的噪声元素和响应目标减少。此外，距离观察者比距离响应目标更远的噪声元素的干扰比距离观察者比距离响应目标更近的噪声元素的干扰更大。这些结果的影响，以观众为中心的表示集中注意力的深度进行了讨论。
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 noice 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 fhat 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.
