A photograph of the eight bell pepper (Capsicum annuum) replicas used as experimental stimuli. From upper-left to bottom-right, the objects are 1, 2, 3, 5, 7, 8, 11, and 12. The six different object pairs used in the current experiment (objects 1 and 3, objects 1 and 7, objects 2 and 11, objects 3 and 7, objects 3 and 8, and objects 5 and 12) represent the most confusable object pairs, as found by Norman, Norman, et al.7. This photograph was taken by the first author, J. Farley Norman.
