Texture segregation shows only a very small lower-hemifield advantage

Possible hemifield differences in texture segregation were investigated for both simple (Fourier, linear) and complex (non-Fourier, second-order) text ure channels. There was only a very small lower-field advantage for texture segregation, consistent with the notion that the major processing in textu re segregation is quite low level, perhaps V1. Complex-channel tasks do not show larger hemifield asymmetries than do simple-channel tasks, which sugg ests that the processes in complex texture channels are not higher level th an those in simple.
