Abstract and Keywords
Recent developments in measurement of eye movements in unconstrained observers have led to a variety of insights that would be difficult to achieve in more constrained experimental contexts. This work shifts the focus away from the properties of the stimulus, toward a consideration of the behavioural goals of the observer. This insight has been accompanied by a growing understanding of the importance of reward in modulating the underlying neural mechanisms of eye movement control, and by theoretical developments using Reinforcement Learning models of sensorimotor behaviour. These developments provide us with the tools to understanding how tasks might control acquisition of information through use of gaze.
