Figure 7.
Comparison of performance (solid circles for human subjects, solid shaded area for the model) and bias (open squares for human subjects, dashed region for model) in the gap closure towards observer looming motion condition. Human psychophysical data is compared to (A) a model based on angular velocity alone, and (B) a model using the τmargin formulation. Error bars and shading are ±1 standard deviation across subjects and model simulations respectively.
