Fig. 4. Data from integration experiments. (A) Ants trained five times at 6-m outbound distance and tested after a 12 m outbound trip (6–12) either immediately (N=18) or after a delay of 24 h (N=17). (B) Ants trained five times at 12 m outbound distance and tested after a 6 m outbound trip (12–6) either immediately (N=17) or after a delay of 24 h (N=17). Individual first turns, medians, and quartiles are shown. Data from the 0 h delay retention (Ret 0) group and 0-trial acquisition (Acq 0) group were pooled and are shown for both 6 m (N=50) and 12 m (N=66) distances.
