N2 - Considerable debate surrounds the extent and manner that motor control is, like perception, susceptible to visual illusions. Using the Brentano version of the Müller-Lyer illusion, we measured the accuracy of voluntary and reflexive eye movements to the endpoints of equal length line segments that appeared different (Experiment 1) and different length line segments that appeared equal (Experiment 3). Voluntary and reflexive saccades were both influenced by the illusion, but the former were more strongly biased and closer to the subjective percept. Experiment 2 demonstrated that these data were the results of the illusion and not centre-of-gravity effects. The representations underlying perception and action interact and this interaction produces biases for actions, particularly voluntary actions.
