Overview of the experimental protocol. After filling in the entry questionnaire, the subjects started the experimental protocol that spanned several days (sessions), where each session included one or multiple experimental tasks performed with (FB) and without (NFB) supplemental feedback. After each condition, the subjects filled in the questionnaires. The protocol was finished once the subject performed each experimental task in at least two sessions. The last step in the study was to fill in the final questionnaire. (* denotes that the starting condition [FB/NFB] was randomized)
