An experiment with two picture categorization tasks with auditory distracters containing redundant information was carried out to investigate the effects distracters, i.e. earcons, have on categorization. In the first task participants had to carry out an extra mental addition task. The secondary task consisted of just the categorization. The dual task situation was expected to lead to longer reaction times and more errors that the single-task situation, possibly providing new insights when analyzed. The results indicated that in conditions in which the earcons contained relevant redundant information significantly fewer errors were made, compared to conditions with no relevant redundant information.
