Independent modulation of motion and vection aftereffects revealed by using coherent oscillation and random jitter in optic flow
We added simulated vertical viewpoint jitter and oscillation to radial optic flow displays designed to induce forward vection. Display jitter and oscillation were both found to increase vection strength during, and reduce motion aftereffects (MAE) following, exposure to the optic flow (compared to no-jitter controls). Display jitter, which induced the strongest vection of all the conditions tested, was also found to increase the duration of vection aftereffects (VAE).
