Comparing oculomotor decision-making models for halting inappropriate actions

Project Details

Sometimes the action we are planning to make is inappropriate. When driving and the crossing light turns green but a pedestrian then steps out in front of you, you need to stop yourself from hitting the accelerator. When trying to catch the cat to put it outside, you need to halt your planned lunge to the right in favour of the new spot to the left the cat has just darted to. The need to halt inappropriate responses occurs innumerable times throughout the day, and not infrequently is used to prevent actions that might result in harm to ourselves or others if left unchecked.

There are several oculomotor models that investigate the need to halt inappropriate eye movements (for example, countermanding and antisaccade experiments). This project examines the commonalities and differences between these models, thereby improving our understanding of how the brain halts inappropriate actions in general.
