Abstract
Almost all current models of early spatial vision assume the existence of independent linear channels tuned to a limited range of spatial frequencies and orientations, i.e. that the early visual system acts akin to a sub-band coder. Some classic studies cast doubt on this notion, however, in particular the results reported by Henning, Hertz \& Broadband (1975) using amplitude-modulated gratings and those of Derrington \& Henning (1989) using 2-D plaid maskers. In our study we explore the unusually strong masking induced by spacetime coincident plaids in more detail: in particular, we determine the masking dependency
on stimulus presentation time and contrast asymmetry between the plaid components. Such data will help to constrain non-linear extensions to the current channels model.
