Do you have to look where you go? Gaze behaviour during spatial decision making


In this paper we present an eye-tracking experiment investigating the relation of gaze behavior, spatial decision making and route learning strategies. In the training phase participants were passively transported along a route consisting of 18 intersections. Each intersection featured two landmarks, some of which were unique while others were non-unique. In the test phase participants were presented with static images of the intersections and had to indicate the direction in which the original route proceeded. We report systematic gaze bias towards the eventually chosen movement direction. Furthermore, we demonstrate that by dissociating the decision relevant information from the location to which a response is directed, these gaze bias effects can be systematically modulated. The results provide novel insights into how attentional processes mediate performance in a route memory task and are related to current theories of visual decision making.
