(A) Experimental design. The vowel vocalization task was performed in three functional runs (as part of a larger speech production study) preceding a functional run related to the supralaryngeal motor tasks. Each motor or resting condition occurred 18 times in a pseudorandomized order. (B) Timeline of a single trial. For each trial, the time interval between the visual instruction onset and the midpoint of the following functional scan acquisition was randomly varied between 4 s, 5 s, or 6 s. In each trial, a 1,000 ms visual instruction informed the participants about the motor condition or the resting baseline (blue rectangle). TR: repetition time; TA = acquisition time.
