Collisions and attention

Figure 1: We ran a series of experiments to determine the source of biases in the perception of anomalous collision dynamics. In a paperbased experiment (a), participants were asked to sketch the predicted post-collision trajectories of two spheres; Using an eye-tracker (b), eye-movements were recorded while participants viewed animations of simple collision events. We are working on extending these studies to a more natural environment, such as a snooker game (c).
