Embodied Choice: How Action Influences Perceptual Decision Making
Fig 3
Simulated 2AFC task with action dynamics (trajectory from Model 3).
For simplicity, movement along the trajectory is at constant velocity. The trajectory depends on the interaction between the decision and action systems, driven by information for the alternatives. An action focus is used to link the decision and action systems, which here drifts from target T2 to T1 with the accumulated information for each alternative.
