Fig 3. Visualization of probability densities of the response for hypothetical experimental trials, according to the MI(yellow), SS(purple), and CI-MA(green) models.
The dashed vertical line in blue marked θV represents visual heading angle; the orange line marked θI represents inertial heading angle. The left panel illustrates that the CI-MA model behaves very similar to the MI model for small discrepancies; the middle panel shows that the CI-MA model averages between the MI and SS model for an ‘intermediate’ discrepancy; and the right panel shows that the CI-MA model behaves very similar to the SS model for large discrepancies. The likelihood of a response according to either model corresponds to the height of the associated density function at the response angle.
