Possible and Impossible Objects

(.zip archive) This image set was created by Pepper Williams for use in several studies on how the 3D structure of objects is represented in visual memory. The unique thing about this set (unlike those created and used by Schacter and Cooper) is that there are three versions of each object (40 objects in total): possible, impossible1 (one impossible "part"), impossible3 (three impossible "parts"). See Williams and Tarr (1997) and (1998) for papers using these stimuli.
