||Selective interference reveals dissociation between memory for location and colour.
Examined whether there is indication of dissociation in processing of visuospatial and colour information in working memory in humans. 20 Ss (aged 18-44 yrs) performed visuospatial and colour n-back tasks with and without visuospatial and colour distractive stimuli presented in the middle of the delay period to specifically affect mnemonic processing of task-related information. In the high memory-load condition, the visuospatial, but not the colour, task was selectively disrupted by visuospatial but not colour distractors. When subvocal rehearsal of the memoranda in the colour task was prevented by articulator suppression; colour task performance was also selectively disrupted by distractors qualitatively similar to the memoranda. The results support the suggestion that visual working memory for location is processed separate from that for colour. (PsycINFO Database Record (c) 2009 APA, all rights reserved)
