Figure 2

(a) Illustration of the left target which participants had to identify (Training session) or reach for (Test session); The left (long) and the center (short) vertical bars were used to cue the participants on the start and midpoint of the scan (left panel); a schematic of the anticipated rotation during the visual rotation is shown in the middle panel, and a schematic of a possible outcome with the SSD shown on the right. The green lines represent the expected hand motion of the participants. (b) The experimental protocol: 40 trials during the baseline block, followed by 4 blocks of rotation with 60 trials each, and a single washout block with 40 trials. Between each two blocks, a 40-sec break was given, along with an on-screen report of the participant's average cumulative score. (c) A schematic of the two possible outcomes of the experiment during the rotation: if there is no cross-sensory transfer (left panel), the error on the VIS trials will drop, while the error in the SSD trials will remain constant; if, however, there is cross-sensory transfer (right panel), the drop in error on VIS trials will be accompanied by a drop in error on SSD trials.
