Time course of two example trials. On each trial, participants had to respond 127 to two tasks that were separated by an unpredictable stimulus onset asynchrony of 300 ms 128 (overlapping task execution, A) or 1200 ms (serial task execution, B). A three-choice color 129 variant of the flanker task, in which the color of the central square had to be indicated (red, 130 yellow, blue), served as Task 1. A two-choice pitch discrimination task was presented 131 subsequently as Task 2, with an auditory sine tone stimulus of 400 Hz or 900 Hz. Participants 132 were instructed to respond as fast as possible to both tasks, in the given order. S1 = Stimulus 133 1. S2 = Stimulus 2. R1 = Response 1. R2 = Response 2. RT1 = response time to Task 1. RT2 134 = response time to Task 2. 135 136

... healthy adult participants worked on a variant of the psychological refractory 120 period (PRP) paradigm, which is commonly used to investigate mutual interference between 121 subtasks in dual-tasking situations (Pashler, 1994;Tombu & Jolicoeur, 2003). The details of 122 the experimental paradigm can be found in Figure 1. to two tasks that were separated by an unpredictable stimulus onset asynchrony of 300 ms 128 (overlapping task execution, A) or 1200 ms (serial task execution, B). ...

... and procedure Experiment 1. Adopting the PRP paradigm from Steinhauser, Ernst, and Ibald (2017), we combined an error-prone three-choice color flanker task and a two-choice pitch discrimination task. The flanker task stimulus (see Fig. 1) consisted of three horizontally arranged squares of .82° edge length. The central target square and the two flanker squares were either red, yellow or blue. While both flanker squares had the same color, this color was always different from that of the target. As three colors were used, it was possible to exclusively present these ...
