Dataset for "A virtual reality approach identifies flexible inhibition of motion aftereffects induced by head rotation"

This dataset comprises of the data presented in the publication "A virtual reality approach identifies flexible inhibition of motion aftereffects induced by head rotation" (Bai et al., 2019) and the codes for data analyses.For the study, we designed a custom VR equipment with a head-mounted display and a motion sensor fastened to a helmet, which could collect real-time data of the observer's movement and deliver it to the computer instantly, thus helping us manipulate the visual stimuli to present according to the profile of the observer's self-motion.Observers performed yaw head rotation (leftward of rightward) as required.

During the head rotation, drifting gratings were presented to them via the VR goggle as the visual motion adapter to induce a motion aftereffect (MAE) after the head rotation ceased. The direction of the visual motion was manipulated to be the same as, opposite to, perpendicular with, or uncorrelated to that of the head rotation. We measured the duration of the MAE that observers then experienced to test whether and how rotating the head during visual motion would affect the MAE induced later, compared with the control conditions where observers did not rotate their heads and kept still when watching the visual motion.For details of the dataset, please see readme.txt in the root directory after unzipping.
