Dr Shigeru Watanabe at Keio University is an unique scientist in that he believes that birds and mice have an ability to distinguish fine art. He has published that sparrows and pigeons have the ability to distinguish one form of painting from the other. This might be a basic pattern recognition by the animals but in his recent work, he has shown that though the animals did not possess a preference for one painting vs. the other, they could form relationships between stimuli and paintings. He treated mice with one pleasurable drug, morphine, when exposed to one kind of painter and saline when exposed to another form of painting. Works from Mondrian and Kandinsky were the two painters that were chosen for this experiment. See if you can tell the obvious difference in styles.
Over time, the mice learnt to distinguish the paintings that were linked to the pleasurable drug. This could be a version of the Pavlovian reflex but it does show that the pattern recognition and the analysis machinery in mice eye and brain are advanced enough to distinguish patterns of different painters.
