Figure 1
Schematic illustration of the experimental setup. The apparatus (1A) with a participant sitting in front of the video screen and the projected targets, wearing a headphone, and the response box with the arrow, and the sequence pattern (1B).
Figure 2
Kinematics of a single participant. Examples of the time series lever position in degree, velocity and acceleration from one participant during acquisition from Trial 3 (A1 to A3) and Trial 150 (B1 to B3).
Figure 3
Element duration during acquisition, retention and transfer testing. Element duration and the standard error of the mean (SEM) during acquisition and during retention and transfer tests (3A) and the mean number of zero crossing and SEM during acquisition and during retention and transfer tests (3B). Note, the abbreviation ST is single-task, and DT is dual-task.
Figure 4
Kinematics of a single participant on the repeated test in a dual-task situation. Examples of the time series lever position in degree (A), velocity (B) and acceleration (C) from one participant on the repeated sequence in a dual-task context. The filled dots in A indicate where the auditory stimuli for the secondary task occurred. The arrows at C provided to demonstrate the impact of the secondary task on the acceleration trace. The abbreviation ‘S’ is for Stimulus, and ‘R’ for response.
