More on the Associative Interpretation of the Indirect McCollough Effect

Following an induction procedure in which a coloured pattern (e.g. spokes) is alternated with a complementarily coloured, homogeneous, patternless circle, subjects report colour after effects on both the pattern presented during induction (i.e. spokes) and on an orthogonal non-induced pattern (i.e. concentric circles). The after effect reported on the induced pattern is the McCollough effect (ME), and the aftereffect reported on the non-induced …
