拟议研究的直接目标是更多地了解 双目三大现象的特征 视觉--立体视觉、双眼竞争和双眼组合或融合。 提出了三条相关的调查线索，每条线索涉及三个方面之一。 主要现象。 调查的方法是心理物理学 范例，其中相当多的数据是从一个相对较小的数量 人类观察者。 立体视觉的研究涉及到立体视觉的形成途径， 该深度信息是从随机元素立体图中提取的 在立体和物理轮廓的相互作用下， 认知变量对增强立体视知觉的作用 感知立体视觉的经验，以及评估立体视觉的方法， 婴幼儿。 关于双眼竞争的研究旨在 更精确地说明在竞争中丢失的信息类型 抑制和竞争抑制之间的关系， 与双眼异常（如斜视）相关的抑制。 的 关于双眼组合的研究试图检验这样的假设， 抑制可能在表面上合作的聚变状态期间起作用 正常的双眼视觉。 该计划的长期目标是 贡献的信息，这将有助于发展的一般理论， 双眼视觉，包括立体视觉、竞争视觉和双眼视觉 在一个单一的框架中。 此外，这项研究还对以下方面产生了影响： 人类双眼视觉异常的病因和治疗。

The immediate goal of the proposed research is to learn more about the operating characteristics of the three principal phenomena of binocular vision--stereopsis, binocular rivalry, and binocular combination or fusion. Three related lines of inquiry are proposed, each dealing with one of the three principal phenomena. The method of investigation is the psychophysical paradigm, wherein considerable data are obtained from a relatively small number of human observers. The research on stereopsis is concerned with the way in which depth information is extracted from random-element stereograms and focuses upon the interaction of stereoscopic and physical contours, the contribution of cognitive variables to enhance the perception of stereopsis, the role of experience in perceiving stereopsis, and methods for assessing stereopsis in infants and young children. The research on binocular rivalry is designed to specify more precisely the kind of information that is lost during rivalry suppression and the relationship between rivalry suppression and the kind of suppression associated with binocular anomalies such as strabismus. The research on binocular combination attempts to test the hypothesis that suppression might be operative during the ostensibly cooperative fusion states of normal binocular viewing. The long-range objective of the program is to contribute information that would aid in the development of a general theory of binocular vision that would encompass stereopsis, rivalry, and binocular combination in a single framework. Moreover, the research has implications for both the etiology and the treatment of binocular visual anomalies in humans.
