The relative detectability of three potentially optimal visual signals derived on the basis of statistical decision theory was measured and compared with that of a one-dimensional analog of the most detectable signal found by Watson et al. [Invest. Ophthalmol. Vis. Sci. Suppl. 20, 178 (1981)]. The latter signal was marginally easier to detect than the other three, but the small differences in detectability preclude our making strong inferences about the nature of visual pattern detection.
