EYE-MOVEMENTS AND THE ASSOCIATIVE BASIS OF CONTINGENT COLOR AFTEREFFECTS - A COMMENT

One of S. Siegel, L. G. Allen, and T. Eissenberg's (1992) recent argum ents in support of associative-learning explanations of colored aftere ffects (CAEs) is that the contingencies underlying these effects are n ot constrained by simple stimulus dimensions, such as contour orientat ion' Specifically, the authors claim to have generated CAEs contingent on sets of spatiotopic relationships between orientation components o f a pattern (as opposed to orientation components per se). The present article illustrates how Siegel et al.'s claims are compromised by the ir failure to adequately address the role of fixation and eye movement s during CAE induction.
