DIFFERENCES BETWEEN â€œEARLYâ€ AND â€œLATEâ€ PROCESSING OF STIMULUS DIMENSIONS IN PERCEPTION? THE ROLE OF CONTEXT INVARIANCE
When a pair of dimensions is tested for perceptual interaction, the outcome can depend on the task at hand. In particular, inconsistencies are found when the same dimensions are tested in detection and in â€˜higher-levelâ€™ judgments. The so-called Redundant Signals Design in detection and Functional Measurement in judgment are discussed for illustration. It is shown that the notion of context invariance is critical for a theoretical resolution.
