Fig. 1. The pulse repetition rates (PRRs, blue line) and pulse durations (red line) for all five simulated bat attack sequences used in the experiment. Each sequence was based on an actual successful bat attack collected during the Triblehorn and Yager (2002) experiment. The gray bar represents the transition phase. Sequences contained either rapid (RT) or gradual (GT) transitions in PRR. The number indicates the slope of the transition in terms of PRR (pps) per 10 ms. Higher slopes indicate faster transitions.
