Box-plot summarizing the fixed effects of the robot-assisted trainings in comparison with the Standard Therapy (ST) on NEPSY-II subscale Theory of Mind. The plot on the left (A) represents pre–post delta scores for each condition; the plot on the right (B) shows performance across three assessment phases (T0–T1-T2). The group that first received RAT improved significantly after the first training phase (pink bars; T0 vs. T1), while the group that initially received ST showed no improvement during that phase (turquoise bars; T0 vs. T1) but improved following RAT (T1 to T2). Horizontal lines indicate statistically significant comparisons (***p < .001).Crossover Effects and Training Retention.
