Vision scientists from the University of Lincoln have found a person's own perceived "norms" about how fast something would usually move can be unconsciously influenced by previously viewed speeds.
For example, researchers reportedly found when study participants were exposed to slow-motion footage of people either running a marathon or walking around, participants judged normal-speed playback as too fast, and it had to be slowed down in order to appear "normal."
And researchers believe the same type of experience would occur for drivers moving from a high-speed condition on a freeway to a slower speed zone. According to researchers, it would take time for them to adjust because faster speeds would feel more normal, and it is up to the brain to continuously compensate for changes in the driver's visual stimulation.
The study was recently published in the journal Scientific Reports.
