some issues on the relation between visual localization and eye movements were discussed. Visual mislocalization contingent upon saccadic eye movements has been sometimes explained as showing inaccuracy of an eye position signal originated from the central oculomotor system. Recent psychophysical studies suggested that the time course of extraretinal eye position signals is not consistent with that of actual eye position and that the visual stability which we experience in the everyday life is not explained in terms of extraretinal eye position signals. Some other possible explanations were presented. It was also shown that the extraretinal eye position signal for pursuit eye movements is inaccurate and not sufficient for informing us of the distance the eye tracked. Finally, the role of vergence eye movements in depth perception was discussed. It was stressed that a small fluctuation of vergence results in a large change of the fixated position and that vergence cannot be a strong cue for depth perception.
