Figure 4


Fig. 4. Bee acquisition of target from distractor. The bold line shows bee (N=10) acquisition with only 40 responses to stimuli, and the broken line bee (N=10) acquisition for 120 responses with quinine hemisulphate used as a punishment for landings on distractor stimuli (same data as in Fig. 3). Insert shows frequency of correct choices in subsequent non-rewarded tests where bees trained for only 40 responses were significantly poorer at recognising the target, but were still able to perform significantly better than chance (see text for statistics).
