Progress of Performance & Difficulty. Illustration of progress in performance and difficulty as a function of trials for a representative participant (FM score: 45) during the training session. Initial difficulty was initially set at its lowest value, and increased adaptively depending on performance. In the doorknob turning task (A), performance was maintained near the challenging point from around 15 trials. In the jar opening task (B), the participant failed to complete the task for three trials near the highest difficulty, but could then complete the task near the end of training. The door locking task (C) was too easy for the participant at all difficulty settings.
