9	Experiment 1 16 dogs
10	Experiment 1 13 out of 16 dogs showed proximity error almost significant negative correlation between trial number and proximity errors ð Stage IV, but can V be learned?
11	Experiment 2
12	Experiment 2 24 dogs, 20 trials each
13	Experiment 2 15 out of 24 scored higher when strings were closer together, three when they were further apart dogs choose a baited over a non-baited string
14	Experiment 3 overlap set-up
15	Experiment 3 no overlap
