ABSTRACT
I measured preference for paintings (Renoir vs. Picasso or Kandinsky vs. Mondrian) in mice. In general mice did not display a painting preference except for two mice: one preferred Renoir to Picasso, and the other preferred Kandinsky to Mondrian. Thereafter, I examined discrimination of paintings with new mice. When exposure to paintings of one artist was associated with an injection of morphine (3.0 mg/kg), mice displayed conditioned preference for those paintings, showing discrimination of paintings by Renoir from those by Picasso, and paintings by Kandinsky from those by Mondrian after the conditioning. They also exhibited generalization of the preference to novel paintings of the artists. After conditioning with morphine for a set of paintings consisting of two artists, mice showed discrimination between two sets of paintings also from the two artists but not in association with morphine. These results suggest that mice can discriminate not only between an artist's style but also among paintings of the same artist. When mice were trained to discriminate a pair of paintings by Kandinsky and Renoir in an operant chamber equipped with a touch screen, they showed transfer of the discrimination to new pairs of the artists, but did not show transfer of discrimination of paintings by other artists, suggesting generalization.

Operant discrimination of paintings by Kandinsky and Mondrian by four mice.The correct response ratio was obtained by dividing the number of response to S+ by the total number of trials. Arrows indicate the start of training with a new pair of paintings. The last bold arrows indicate a pair of Picasso and Renoir.

Arrows indicate the start of training with a new pair of paintings. The last bold arrows indicate a pair of Picasso and Renoir.

Mentions: Figure 2 shows the results of operant discrimination between paintings by Kandinsky and those by Mondrian. Small arrows indicate start of a discrimination task with new pair of paintings by Kandinsky and Mondrian. The fastest mouse required 16 sessions and the slowest 43 sessions (average 31.5 sessions) to learn the first task. To learn the fourth task, the fastest mouse needed 2 sessions and the slowest 4 sessions. The correct response ratio in the first session of the second task was 0.55 to 0.85 (average 0.74) and that in the fourth task was 0.70 to 0.85 (average 0.79). Thus, the mice were able to discriminate paintings and transfer the discrimination to novel stimuli. When they saw a pair of Picasso and Renoir (indicated by bold arrows), the mice did not show transfer of discrimination. The correct response ratio in the first session was 0.50 to 0.60 average 0.57). Paired t-test revealed a significant difference in correct discrimination ratio in the first session between the last Kandinsky-Mondrian discrimination task and the Picasso-Renoir discrimination task (t(3) = 8.88,P<0.005). They were able to learn the new task but required 10 to 15 sessions (average 13.5 sessions). There was a significant difference in number of sessions to reach the criterion between the last Kandinsky-Mondrian discrimination task and the Picasso-Renoir discrimination task (t(3) = 8.20,P<0.005). These results demonstrate within artist transfer and no cross artist transfer suggesting generalization within the artist.
