不同类型的立体视敏度进行了研究与任务改编的视觉方向敏锐度的研究。动态，随机元素立体图描绘多个表面的深度和时间2AFC程序被用于所有的测量。这三个任务要求检测深度偏移（超敏锐度任务）、深度轴增厚（超分辨率任务）和表面之间的深度轴间隙（间隙分辨率任务）。三个任务的持续时间分别为视网膜视差的3秒弧、30秒弧和200秒弧的量级。这些结果是类似的视觉方向任务上，他们的图案，这表明所涉及的基本判断是相似的。结果用于估计水平视差处理的固有噪声。
Different types of stereoscopic acuity were studied with tasks adapted from studies of visual direction acuity. Dynamic, random-element stereograms portraying multiple surfaces in depth and a temporal 2AFC procedure were used for all measurements. The three tasks requried detection of a depth offset (Hyperacuity task), a depth-axis thickening (Superresolution task), and a depth-axis gap between surfaces (Gap Resolution task). Thresholds for the three tasks were on the order of 3 sec arc, 30 sec arc and 200 sec arc of retinal disparity, respectively. These results are comparable to those for the analogous visual direction tasks on which they were patterned, suggesting that the underlying judgements involved are similar. Results are used to estimate the intrinsic noise of horizontal disparity processing.
