Differential changes in human perception of speed due to motion adaptation

Hietanen, Marcus; Crowder, Nathan; Ibbotson, Michael


Visual systems adapt to the prevailing image conditions. This improves the ability to discriminate between two similar stimuli but has the side effect that veridical perception is degraded. For example, prolonged driving at 100 km/h may reduce the perceived speed to 80 km/h but improve the sensitivity to changes in the prevailing speed. Here we use radially expanding flow fields with a wide combination of adapt and test speeds to study human speed perception. Adaptation at speeds higher than...[Show more]
