Do target angular size-change and blur cues interact linearly in the control of human accommodation?
Calculations made using the data of Kruger and Polar [J. opt. Soc. Am. A2, 1832-1835 (1985); Vision Res. 26, 957-971 (1986); Vision Res. 27, 555-567 (1987)] show that for three of the four subjects they studied, size-change and blur cues do not interact linearly in the control of accommodation. A simple non-linear interaction model is shown to fit the data for all four subjects.
