Fig. 3. Results of Expt 1, shape discrimination and generalization between colours.
The same bees as in Fig. 2,
trained with a blue square vs a yellow square. The inset shows the
choice frequency (CF) obtained during the training and the number of choices
(N) on which it is based. The trained bees were then offered a choice
between a square and each of four novel shapes (abscissa). In the tests, both
test shapes were either blue, as was the positive training shape, yellow, as
was the negative training shape, or black, which was novel to the bees. The
bars depicting the CF obtained in favour of the square are coloured according
to the colour of the two shapes used in each test. The number above each bar
denotes the total number of choices recorded in the test.
