Fig. 3. Frequency of stimulus selection plotted against the total number of
response decisions (landings and rejections). (A) Honeybee acquisition
(±1 s.d.) whilst being trained with differential conditioning to target
and distracter stimuli representing similar complex scenes that might be
encountered in a forest. Acquisition in experiment 1 is indicated by circles
and in experiment 2 by squares. Experiment 2 used a different target and
distractor combination; acquisition was very similar, and triangles and bold
line show pooled data. (B) Pooled data for the frequency with which bees made
abort flights (bees approached a stimulus and then turned away and left
without making any contact); the solid line shows a significant negative
correlation of aborts to target stimuli with increasing experience (see text
for statistics), and the broken line shows no significant correlation of
aborts to the distractor stimuli.
