Modeling the simulated real-world optic flow motion aftereffect.
We investigated the simulated real-world optic flow motion aftereffect (MAE) (illusory sense of moving backward following adaptation to expansive optic flow). In Experiment 1, adaptation duration was either 30, 120, 240, or 480 s.


RESULTS
duration of the MAE grew with increasing adaptation duration. In Experiment 2, the MAE was measured across different combinations of values of global optical flow rate and optical edge rate.


RESULTS
the aftereffect was selective for global optical flow rate, suggesting that the aftereffect reflects gain changes at processing levels where a sense of self-motion is generated. RESULTS were used in a computational model of this MAE, which was a modified framework by van de Grind et al. [Vision Res.44, 2269 (2004)].
