Figure 2.

Stimulation protocol. The figure presents a depiction of the blocks within each run and the trials within each block. Block orders were pseudorandomized and counterbalanced across runs. The six letters used for the Write With Ink, Watch Static, and Watch Dynamic blocks were necessarily the same set of six letters, and the same set of six letters was also displayed in the Watch Typed condition. Letter orders within a block were randomized. Block instructions and letter names were prerecorded. Block instructions were played at the beginning of each block to alert participants to the task. Letter names were played at the beginning of each trial to alert the participants to the letter that they should write or to the letter that would be displayed.
