Fig. 5. Paths of ants with restricted training, after reaching F1 or F2. (A) Probe tests grouped according to the number of training trials after the switch to F2. Paths are shown from the point where ants reached within 20 cm from F1. Trajectories are from 30 ants and the proportions of trajectories that reached within 20 cm of F1 were 68% (runs 1–10), 47% (runs 11–20) and 40% (runs 20+). (B) As above, for test runs that reached within 20 cm of F2. The proportions of trajectories that reached within 20 cm of F2 were 34%, 86% and 81% for the three groups.
