Differential effect of noise on tasks of varying complexity.

The method of simultaneous tasks was used to test the hypothesis that the deleterious effect of noise on performance varies as a function of task complexity. 48 Ss performed on 1 of 2 complexity levels of a 4-choice RT task and, at the same time, performed a secondary auditory monitoring task. All S...

Sumario:The method of simultaneous tasks was used to test the hypothesis that the deleterious effect of noise on performance varies as a function of task complexity. 48 Ss performed on 1 of 2 complexity levels of a 4-choice RT task and, at the same time, performed a secondary auditory monitoring task. All Ss performed in both quiet and in noise. Performance indexes were RT and secondary-task errors. Noise produced a significantly greater increase in secondary-task errors when the secondary task was paired with the complex primary task than when it was paired with the simple primary task. Secondary-task performance provided a more sensitive measure of both task complexity and the effect of noise than did the RT measure.
