虽然人类的心理物理学结果表明，运动视差和立体视觉都是有效的深度线索，但不清楚非人类灵长类动物是否也是如此。作为第一步，我们评估的程度，恒河猴能够处理深度信息的基础上，单独的运动视差相比，立体视觉。我们构建了一个独特的显示，使我们能够提供深度线索的立体视觉或运动视差或两者兼而有之。我们的研究结果表明，猴子可以处理深度信息传达的运动视差和立体视觉。与人类一样，运动视差对深度辨别的效果不如立体视觉。这些研究结果准备努力评估运动视差和立体视觉是如何在视觉系统中共同处理。(C)2002爱思唯尔科技有限公司。保留所有权利。
Although human psychophysical results show that motion parallax and stereopsis are both effective depth cues, it is not clear whether the same is true for non-human primates. As an initial step, we assessed the extent to which rhesus monkeys are capable of processing depth information based solely on motion parallax as compared with stereopsis. We constructed a unique display that enabled us to provide depth cues by either stereopsis or motion parallax or both. Our results show that monkeys can process depth information conveyed both by motion parallax and stereopsis. As in humans, motion parallax was somewhat less effective for depth discrimination than was stereopsis. These findings prepare efforts for assessing how motion parallax and stereopsis are co-processed in the visual system. (C) 2002 Elsevier Science Ltd. All rights reserved.
