a Tactile detection threshold measurement: while the frequency was set at 30 Hz, the intensity of the stimulation gradually increased or decreased (methods of limit) to determine the participant’s threshold. b Two-alternative forced-choice task: participants had to determine whether the frequency of the second stimulation (F2) was higher or lower than the first one (F1). The frequencies used for Experiments II and III are detailed in the right part of the Figure (3 context-setting blocks centered on 30 Hz, followed by two time-order effect blocks centered on 26 or 30 Hz).
