Mean MEP amplitudes from the FDI and ADM muscles, displayed as z-scores, for the static hand, free observation, finger-focused and ball-focused conditions.

<p>Positive z-score values indicate that the MEP amplitude in that condition was greater than the mean MEP amplitude in that muscle across all conditions. Negative z-score values indicate that the MEP amplitude in that condition was less than the mean MEP amplitude in that muscle across all conditions.</p

Mean raw MEP amplitude values (± SE) from the FDI and ADM muscles for the static hand, free observation, finger-focused and ball-focused conditions.

Areas of interest (AOIs) around the hand (blue box), index finger (orange box) and ball (red box) from which eye-tracking fixation data were extracted.

<p>A fourth area of interested, termed ‘other’ comprised any part of the visual display outside of the hand, index finger and ball AOIs.</p
