Abstract

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)].

  10. In a control experiment, four observers viewed our SRW optic flow display and a display showing a moving spiral pattern (both displays had the same dimensions, similar to our optic flow display in the main experiment). Five trials were collected for each display, presented in random order. Observers rated each display on a scale of 0 to 10, with 0 indicating no sense of self-motion and 10 indicating a very strong sense of self-motion. Average rating of our optic flow display was 8 (S.E.=0.4); average rating of the spiral display was 2 (S.E.=0.5). Our optic flow display generates a much greater sense of self-motion than a spiral display.

  21. Adaptation speeds used in the main study ranged from 50to400 m/s, which corresponded to 112.5-900 mph, respectively. While these speeds were excessive relative to highway speeds, our altitude of 5 m made the global optical flow rate (e.g., 20 eyeheights/s) comparable to that encountered at highway speeds (e.g., 45 mph) when individuals travel sitting in a car at an altitude of about 1 m. To control for this, we had four observers, at an altitude of 1 m, adapt to our SRW optic flow for a duration of 2 min or 8 min, at speeds of 20 m/s(45 mph) or 40 m/s(90 mph); thus global optical flow rate was 20 or 40 eyeheights/s, respectively, as in the main study. Results: for adapt duration of 2 min, average MAE duration was 18.8 s and 22.6 s for the 20 m/s and 40 m/s adapt speeds, respectively; for adapt duration of 8 min, average MAE duration was 39.8 s and 52.3 s for the 20 m/s and 40 m/s adapt speeds, respectively. Thus, our results from the main study generalize to more terrestrial speeds typically encountered in the real world.

  25. We considered adding multiple leaky integrators in serial order with a group of local mechanisms converging onto a head-centric unit at a higher (global) level of processing, the latter of which would adapt with a longer time constant. We rejected this scheme in favor of multiple parallel mechanisms at each processing level because showed that local MAEs can be very long, and this study showed that global MAEs can also be very long; thus both local and global levels require parallel mechanisms with a range of time constants.
