Figure 1.
Figure 1.
Exemplary images demonstrating the dispersion of a female subject at the end of all tasks (melody and text, text, and melody). Below each image, the diagrams show the temporal dispersion to the front (x-direction). The upper row refers to the soft (−) versions of the tasks, and the lower row refers to the loud (+) versions of the tasks. The red curves represent the individual subjects, and the green curve represents the median. The 0 point on the x-axis in the time scale refers to the end of the task. M = melody; MT = melody and text; T = text.

Figure 2.
(A–C) Median traces for the x-dimension (front) (A), y-dimension (left–right) (B), and z-dimension (up–down) (C) and all tasks. The 0 point in the time scale refers to the end of the task. The different colors refer to the three tasks (green: melody and text, yellow: text, and blue: melody). The solid lines show the loud (+) tasks, and the dashed lines the soft (−) tasks. (D) The directions in the two camera perspectives. M = melody; MT = melody and text; T = text.
