Composite score built by PCA over six behavioral metrics; the LME showed "a significant main effect of Block", F(4, 115) = 16.53, p < 0.001. Only a test statistic is printed, so no effect size is reported.

• Rotational path length does not reliably decrease over teleoperation training, suggesting continued exploration of joint-level strategies — related
• Teleoperation trainees become more efficient over training, with reduced translational path length and faster trial durations retained at delayed testing — related
• Task errors (drops, collisions, collision duration) decrease significantly over teleoperation training and are retained — related
• Subjective cognitive workload decreases across teleoperation training and lower workload is associated with higher performance — related
