Is the "face aftereffect" retinotopic or spatiotopic?

Selective adaptation to one face leads to systematic distortion in the appearance of subsequently presented faces, a phenomenon which has been called the "face aftereffect". Here we compared the strength of the face aftereffect when, following an eye movement, two adjacent test faces are presented, one at the same retinal position as the adapting face and the other at the same spatial position as the adapting face. The adjacent tests provide a direct measure of the relative strength of retinotopic versus spatiotopic effects and the results show that the retinotopic aftereffect is stronger than the spatiotopic aftereffect.
