Interfering with the central executive by means of a random interval repetition task . Four dual-task experiments are reported in which a short-term memory task is performed concurrently with a random interval repetition task , which was designed to interfere with functions normally attributed to the central executive in the working memory model of Baddeley and Hitch ( 1974 ) . The task was found to interfere with supra-span serial recall and with backward memory span , but did not disrupt performance on a forward-memory-span task . The effects were observed in dissociation with effects of articulatory suppression and matrix tapping , so that the locus of the effects of the new task is not due to the slave systems . In addition , single-task random-interval repetition performance was sampled and compared to performance in the dual-task conditions of all four experiments . Although quality of tapping performance differed between the single-task and the dual-task conditions , it was not related to recall performance . All the results are discussed with reference to the working memory model .
