Gaze behaviour in speed and time-to-arrival judgements

In two separately performed 2IFC tasks, participants judged the speed (“Which vehicle is faster?”) and time-to-arrival (“Which vehicle will arrive first?”) of an approaching vehicle. Eye movements were recorded while participants performed the tasks. Road scenes were created in Unity simulating the view of a pedestrian as standing at the edge of a zebra crossing.

The movie shows one trial presented to the participants in the time-to-arrival discrimination task.
