Comparison between model predictions and experimental data.

Experimentally measured DTs (red circles) are well described by the DDM with leaky integration (blue line). The DDM with normal integration (black dashed line) provides a poor fit to the experimental data. Error bars represent ±1 standard error of the mean. For graphical purposes, models predictions were averaged over ten simulations of the stochastic models and smoothed over three consecutive values (moving average).
