Watanabe et al 1995 Pigeons discrimination of paintings by Monet and Picasso. Journal of the Experimental Analysis of Behavior, 1995, Vol.63, No.2, Pp.165-174
[not in handout, see intranet]Expt 1 8 naive pigeons and 2 chambers, one with video, one with slides
They used 10 Monet’s and 10 Picasso’s as training, and selected “typical” pictures
During training, for each session 20 paintings were presented once each in random order, for 30 seconds each. During positive stimuli, pecks at the picture were reward at unpredictable intervals, on average once per 30 seconds.
After training, used 3 new Picassos, and 3 each also of new Monet, Cezzanne, Braque, and Delacroix an earlier “Romantic” history painter whose use of color influenced both the impressionists, and Picasso.)
Test 1 was monochrome of all training pictures; Test 2 was out of focus (to examine the role of contour); Test 3 all the training S were used by 3 S+ and 3S- were upside down and 3 similarly were left-right reversed. plus six normal stimuli were presented; Test 4 was the new pictures.
(During transfer tests, no rewards at all were given)
In test 4, birds trained to respond to Monet showed high rates to new Monets and to Renoir and Cezanne.
Birds trained to Picasso’s did not generalize quite as much to Braque and Matisse and may therefore have been memorizing individual pictures.
Responding to Delacroix was intermediate.
