From: Handedness did not affect motor skill acquisition by the dominant hand or interlimb transfer to the non-dominant hand regardless of task complexity level

Figure 4

Motor skill acquisition and interlimb transfer at different sequence complexities after dominant hand motor sequence practice. Panel (A) Participants performed the motor sequence tasks with less accuracy at level 3 and level 4 after the practice with their practicing dominant hand, regardless of handedness. Moreover, motor sequence errors increased with the increase in sequence complexity in the non-practicing hand. Panel (B) The practice produced motor skill acquisition indicated by a decreased RT at each level post versus pre-test. In addition, the motor skill practice also induced interlimb transfer of decreased RT at levels 1, level 2, and level 4, regardless of handedness. Results also suggest an interlimb transfer of decreased MT at each level, regardless of handedness. The boxplots show the median, the upper, and lower quartiles, and the min and max value of the groups. “ × ” within the boxplot represents the mean line. ‡ time × sequence complexity interaction effect; † main effect of sequence complexity, * p < 0.05.
