研究了知觉独立性的几种形式。这些包括采样独立性，维度正交性，刺激可分性和完整性，以及性能奇偶性。提出了一个通用的多元知觉理论，并给出了知觉独立性的精确定义。这些相关的概念，然后在这个理论的框架内检查，并阐明其理论上的相互关系。结果表明，没有一个概念是等同于感知独立，但如果可分性举行，那么采样独立性是等同于感知独立。几个简单的测试的可分性建议，可以适用于相同的数据作为抽样独立性。维度正交性测试的独立性，只有当一些强的分布假设的刺激的感知效果。反应时间和基于信息的性能奇偶校验标准进行了检查。经验测试这些概念的潜力进行了讨论。
Several varieties of perceptual independence are investigated. These include sampling independence, dimensional orthogonality, stimulus separability and integrality, and performance parity. A general multivariate perceptual theory is developed, and a precise definition of perceptual independence is offered. Each of these related concepts is then examined within the framework of this theory, and their theoretical interrelationships are explicated. It is shown that none of the concepts are equivalent to perceptual independence but that if separability holds, then sampling independence is equivalent to perceptual independence. Several simple tests of separability are suggested that can be applied to the same data as sampling independence. Dimensional orthogonality is shown to test for independence only if some strong distributional assumptions are made about the perceptual effects of stimuli. Reaction time and information-based performance parity criteria are examined. The potential for empirically testing each of these concepts is discussed.
