Three different experiments using different pigeons (Wasserman et al., 1993; Kirkpatrick-Steger, Wasserman, Biederman, 1996, 1998) involved testing with scrambled versions of the watering can, the iron, the desk lamp, and the sailboat. In all three studies, the original drawings were discriminated above 80% correct at the end of training. Performance to the scrambled versions was significantly poorer than the performance to the original versions in all three studies. However, performance to the scrambled versions consistently exceeded the chance level of 25%. The level of performance to the scrambled versions is consistent with the notion that the pigeons were sensitive to the change in the spatial organization of the components, but they must have still recognized some features of the original objects because of the above-chance performance to the scrambled versions.
