Awe, Cynthia A., Johnson, Walter W. and Schmitz, Fred (1989): Inflexibility in Selecting the Optical Basis for Perceiving Speed. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 1440-1444.

“Five subjects participated in an experiment designed to test if people could selectively attend to either edge rate (frequency of passing texture units) or flow rate (optical velocity of texture units) as the optical basis for controlling their own forward speed. Subjects continued to use edge rate as the basis for controlling forward speed, even when instructed to use flow rate and given feedback about their success in using it. The results are interpreted as evidence of inflexibility in selectively attending to information for self-speed.”
