Fig. 6From: The impact of predictability on dual-task performance and implications for resource-sharing accountsAn example of a sequenced dual-task trial in Experiment 2a. A tracking target followed the sinusoidal path, which was invisible to the participants. Circles along the tracking path represent the occurrence of distractor sounds; crosses along the tracking path represent target sounds. All sounds had varying inter-stimulus intervals. The only regularity in the predictable condition was the occurrence of a target sound every fourth soundsBack to article page
