  Figure 1. Representative design of a participant engaging with the MoveHero software task (Research Group and Technological Application in Rehabilitation—PATER Group, São Paulo, Brazil). (A) Illustration showing a successful hit by the participant, with the targeted sphere highlighted. (B) Illustration depicting a miss by the participant, indicated by a red X on the sphere. (C) Illustration of the task being performed using the touchscreen. The spheres are ordered from left to right in the following colors: blue, green, red, and purple.

  Figure 3. Representation of the mean and standard error of HRV indices (Time domain: Mean HR, Mean RR, SDNN, RMSSD, and PNN50) across sequences (A: abstract-concrete and B: concrete-abstract) and assessments (Rest–pre and post, Activity—D1 to D10).

  Figure 4. Representation of the mean and standard error of HRV indices (Frequency domain: LF n.u., HF n.u. and LF/HF; and Poincaré plot analysis: SD1 and SD2) across sequences (A: abstract-concrete and B: concrete-abstract) and assessments (Rest–pre and post, Activity—D1 to D10). In the LF/HF graph, the dotted line indicates the ideal reference value of 1 for this measure.
