Figure 1
Experimental design for Experiment 1. The pretest was done for familiarization and stimuli were randomized preventing learning. A predictable tracking task contained a repeating middle segment (i.e. rand-rep-rand), an unpredictable tracking tasks contained three random segments (i.e. rand-rand-rand). The predictable audio task was a tone sequence (i.e. sequence), with every fourth tone being the target tone. The unpredictable audio task used the same tones but in a random order (i.e. random). ST = single task, DT = dual-task.
Figure 2
Tracking results from the Test Block and Retention Test in Root Mean Square Error (RMSE). Bars within a cluster show the tracking performance for repeating and random segments per group while the different cluster represent the conditions of the auditory task. We found significantly better tracking on repeating segments, but no differences between groups or tracking with sequenced or random tones. Error bars represent the standard deviation of the mean.
Figure 3
Reaction time results from the Test Block and Retention Test. Bars within each cluster show the RTs for sequenced and random tones per Group. Cluster on the x-axis represent the different conditions of the tracking task. Reactions to sequenced tones were significantly faster, but there was no difference in reaction times while tracking repeating or random segment. Error bars represent the standard deviation of the mean.

Bars within a cluster show the tracking performance for repeating and random segments per group while the different cluster represent the conditions of the auditory task.
