Example psychometric functions from two probe locations (open symbols, 1.43° from the test field edge; filled symbols, 0.20° from the test field edge) are shown for one observer (BXB) in the quadrature-phase motion cancelation experiment. The 0.025 c/d inducing grating was counterphased at 1 Hz and test field height was 3°.
