FAB scores	𝑡0	𝑡1	Mean variation	𝑃
Total	11.20 (2.971)	11.30 (3.309)	0.115 (1%)	0.738
Similarities	0.90 (0.810)	0.87 (0.826)	−0.033 (4%)	0.766
Lexical fluency	1.93 (0.873)	1.72 (0.968)	−0.213 (11%)	0.022*
Motor series	2.15 (0.946)	2.25 (0.925)	0.0984 (4%)	0.451
Conflicting instructions	1.77 (1.131)	1.92 (1.187)	0.1475 (8%)	0.268
Go-No Go	1.51 (0.868)	1.56 (1.009)	0.0492 (3%)	0.717
Prehension behaviour	3	3	0

Values are mean standard deviation or mean variation (percent variation). Negative value means decrease from 𝑡₀ to 𝑡₁. 𝑃 value is significance for paired sample student’s 𝑡-tests. Prehension behaviour scores remained constant throughout the study. *𝑃<0.05.
