Fig. 4. Simulated phonotactic movements of agents towards synchronized signals in a
virtual arena, with a time delay of 140 ms (A), and with no time delay (B). In
both cases, the variable indecision was set to 1.5. If the time delay was 140
ms and indecision was set to 0.0 (C), all agents moved to the follower signal,
but the phonotactic path was rather straight, which was never observed with
real females in the arena (compare with
Fig. 1A). By contrast, when
indecision was set to 0.45 (D), most agents moved randomly in the virtual
arena.
