The binocularly induced McCollough aftereffect was stronger for 15 naive undergraduates when orientation hues were tested simultaneously than sequentially. The hues were considerably weakened in a monocularly tested group in comparison to a binocularly tested group. In a second study, with 32 subjects, long-lasting orientation-specific McCollough aftereffects generalized to thinner lines and were reduced under monocular resting conditions when binocularly induced. It is concluded that these results support the idea that the effect appears to be mediated centrally and to be enhanced by simultaneous color contrast.
