From: The life-span trajectory of visual perception of 3D objects
Stimuli and experimental design (a) Examples of possible (left panel) and matched impossible objects (right panel). Note that there are minimal physical differences between the two object types, but the perceptual experience in viewing these two object sets is substantially different. (b) Experiment 1: Same-different discrimination of matched objects: Participants performed same/different discriminations on sequentially presented objects, which were physically highly similar even in the ‘different’ trials. (c) Experiment 2: Comparison of depth information: Participants judged which dot is closer in depth - the red or the green dot. (d) Experiment 3: Same-different discrimination of non-matched objects: Participants performed same/different classifications on sequentially presented objects, which were physically different.
