A computational model of stereoscopic prey capture in praying mantises
Table 3
Values of Mdata (mean number of strikes per trial) used for optimisation.
Columns show stimulus diameter; rows show stimulus stereoscopic distance. For the top 3x4 cells (distances 2.5-5.63cm and sizes less than 38°), data was derived from [10] by taking the difference between the total number of strikes recorded for crossed vs uncrossed trials for the given stimulus, divided by the total number of times each stimulus was presented (Ntrials = 68). This was non-negative in all cases except distance 5.63cm and size 16.88°, where it was -0.04 Zeros for size = 38°, distance = 10cm and monocular stimuli are synthetic data included to force the optimisation to choose parameter values which predict very low strike rates for these conditions, in keeping with our observations.
