Action-specific perception of speed is independent of attention [PDF]
Attention, Perception, & Psychophysics, 2016 According to the action-specific account of perception, a perceiver's ability to act influences how the environment is perceived. For example, in a computer-based task, participants perceive fish as moving faster when they use a smaller net, and are thus less effective at catching the fish (Witt & Sugovic, 2013a).
