(A) In the control imagery experiment, subjects were asked to read or imagine words in the regular alphabet or in visual and tactile Braille or to touch or imagine everyday objects. (B) Similar to the Main experiment (Figure 1C), stimuli in the control experiment were presented in blocks. In each block, after a sound indicating they should lift their fingers from the fiberglass table, subjects heard an auditory instruction informing them about the next task (read/touch or imagine). After 8–12 s, a sound signaled them to put their fingers down. Subjects began to read/touch/imagine after 4–7 s, when they heard the name of the stimulus to be read/touched or imagined. (C) Blocks in the main experiment consisted of 8 stimuli: words, control stimuli or fixation dots in the case of tactile conditions. Each stimulus was presented for 3500 ms and was followed by a 500 ms fixation dot, which was accompanied with a metronome tick indicating the change of the stimulus for the tactile conditions. (D) Blocks in the control imagery experiment consisted of 6 stimuli. After a 500 ms fixation dot, an auditory recording of the name of the subsequent stimulus was presented, either with (read/touch task) or without the stimulus (imagery task). For object stimuli, the block duration was the same, but only one stimulus was presented per block.
