Fig. 4. The average behavioral responses (diamonds) and predicted trigger times (triangles) relative to time to `contact' for eight mantids (represented by color) to the two gradual transition simulated attack sequences. Colors represent the same individuals as in Fig. 3. The black line represents the PRR. The gray bar is the same as in Fig. 1. Placement of each symbol along the y-axis is based on the PRR of the sequence at that time relative to `contact.' The spread of the trigger point and behavior data differ due to individual differences in the response latency measured for predicting the trigger points (see Materials and methods). Both predicted trigger times and behavioral responses occur during the transition period for GT1. The same is true for half of the individuals for GT2, although half of the behavioral response occur just after the transition period.
