Argues that the nature of the stimulus is an important variable determining how information is processed. 2 major stimulus concepts are discussed: dimensional integrality vs. separability, and state vs. process limited stimuli. These concepts relate to the effects of stimulus redundancy on discrimination. There will be a gain with redundancy: (a) if the need for redundancy is due to a process limitation and the redundant dimensions are integral, or (b) if the need for redundancy is due to state limitation and the redundant dimensions are separable. Redundancy can also lead to improvement in discrimination if the stimulus elements can be integrated into a gestalt whole. (28 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
