Abstract
Two experiments assessed the effects of two levels of stimulus redundancy and three levels of irrelevant visual stimulation on performance in a successive- discrimination task and in a reproduction task. The results indicated that increases in redundancy facilitated performance in the reproduction task but had no appreciable effect on performance in the successive-discrimination task. Performance significantly decreased in both tasks as the amount of irrelevant stimulation increased. These findings are discussed in terms of the different strategies that appeared to underlie performance in the two tasks.
