Behavioral results. (A) Sum of the temporal components of skill acquisition. Online (within-session) and offline (between-days) effects and total learning (online + offline) in NF1 patients (purple bars) and in healthy (green bars) participants are shown. Note the significantly greater magnitude of total learning in the healthy control group predominantly driven by greater offline effects. (B) Online effects across training days revealed a reduction in the early acquisition phase (fast-online learning) in NF1 patients. (C) Summary of the motor skill acquisition during the whole training period (5 days). Data show mean ± SEM, * indicates p < 0.05.
