Kohler's theory of transposition was tested with a simultaneous discrimination task which was a replication of Feeney's study with rats in 2003. The subjects, 2 adult dogs, were to discriminate between a large circle (S+) and smaller circle (S-) in a T-maze for the initial phase. Discrimination was not successful; as such the subjects did not move onto the second phase where the rule "choose the bigger shape" was to be tested with a large circle or triangles with randomly assigned probe trials. A single sample t-test displayed the two subjects did not do better than chance in the initial phase. Therefore Feeney's experiment did not replicate over from rats to dogs, and changing the format of Feeney's experiment would be recommended to accommodate the differences between species.
