(On a side note for all, we will soon be making a face stimuli database available which consists of 12 Caucasian males, each photographed professionally under 6 different angle (0, 10, 20 ,30, 40 ,50 degrees) each under 6 different expressions (neutral, happy, sad, angry, surprise, fear, disgust).) However, just to give you a heads up (and to potentially save you some time and effort!), we have just done that experiment and have just submitted it for publication. The study is a same/different matching task where one of the following changes occurs: - whole face - top half of the face - bottom half of the face - eyes only - mouth only - nose only As you would expect, we find that for both reaction times and percent correct, subjects find the images harder to discriminate exactly in the order above (ie. faster and more efficient at detecting changes to the eyes than to the mouth). I would be happy to send you our paper once it has been accepted (hopefully!). Let me know if you would still find the stimuli set helpful.

Does anybody have a set of face stimuli which has pairs of faces differing by only one feature (ie different eyes with all other features identical or different noses with all other features identical)? Thank you very much for your help Aisling Conway University College Dublin
