A variety of converging operations demonstrate key differences between separable dimensions, which can be analyzed independently, and integral dimensions, which are processed in a non-analytic fashion. A recent investigation of response time distributions, applying a set of logical rule-based models, demonstrated that integral dimensions are pooled into a single coactive processing channel, in contrast to separable dimensions, which are processed in multiple, independent processing channels. This paper examines the claim that arbitrary dimensions created by factorially morphing four faces are processed in an integral manner. In two experiments, 16 participants completed a categorization task in which either upright or inverted morph stimuli were classified in a speeded fashion. Analyses focused on contrasting different assumptions about the psychological representation of the stimuli, perceptual and decisional separability, and the processing architecture. We report consistent individual differences which demonstrate a mixture of some observers who demonstrate coactive processing with other observers who process the dimensions in a parallel self-terminating manner.
各种趋同操作表明了可分离维度和整体维度之间的关键差异，可分离维度能够独立分析，而整体维度则以非分析方式进行处理。最近一项关于反应时间分布的研究，应用了一组基于逻辑规则的模型，结果表明整体维度被汇集到一个单一的共同激活处理通道中，这与可分离维度不同，可分离维度是在多个独立的处理通道中进行处理的。本文探讨了通过对四张面孔进行因子变形而创建的任意维度是以整体方式进行处理这一说法。在两个实验中，16名参与者完成了一项分类任务，其中以快速的方式对直立或倒置的变形刺激进行分类。分析重点在于对比关于刺激心理表征、感知和决策可分离性以及处理架构的不同假设。我们报告了一致的个体差异，这表明一些观察者表现出共同激活处理，而其他观察者则以平行自终止方式处理维度。
