Dear all, over the years I have tried various face adaptation experiments, with mostly incoherent results, and watched puzzled as everyone else publishes neat little findings. I began to suspect strong temporal effects and we have finally managed to publish some results demonstrating this with adaptation to antifaces: almost all the effect derives from the first few trials; it is as if whatever is adapting gets 'tired' after that. It may be that others have picked up on this already but I figured it might be useful to draw attention to the finding in case there are those who, like me, are baffled by otherwise strange results. http://www.frontiersin.org/perception_science/10.3389/fpsyg.2012.00019/abstr...
