Re: [Face-research-list] time course of adaptation

Hi Peter et al. Thanks for sharing this, it is a good point to make and definitely rings true from my informal experience over the years. Years ago when we did the anti-face adaption paper, David Leopold did the psychophysics at MPI with quite beautiful and elaborate adapting techniques, and zillions of trials on a few subjects. Simultaneously, I did a "quick and dirty" version of short adaptation trials with less fuss and more subjects in Texas. I did the second version because I was worried that people would think it required methods that were too complicated to get the result. We both got the same results, and in the end, we laughed about the fact that he was used to testing monkeys (very cooperative) and I was used to dealing with undergrads with a short attention spans. His data were lovely so in the first submit of the paper, we used only his data. As it turned out, my worry about how the complexity of the procedure would seem to reviewers proved true, and we got a comment much like I had anticipated -- how much data and time you needed to get the effect?? - given that we already had the data from the TX experiment, this comment was easy to answer by just including the data or noting them, I forget which. I think the temporal questions fascinated David especially vis a vis more standard low level adaptation. He, Gill Rhodes, Kai-Marcus Muller and Linda Jeffreys have a paper on temporal effects that is well worth reading.

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/abst… Peter Peter Hancock Professor, Deputy Head of Psychology, School of Natural Sciences University of Stirling FK9 4LA, UK phone 01786 467675 fax 01786 467641 http://www.psychology.stir.ac.uk/staff/phancock ________________________________ The Sunday Times Scottish University of the Year 2009/2010 The University of Stirling is a charity registered in Scotland, number SC 011159.
