The aim of the subjects was to track a moving light target and to locate the change in its intensity (its disappearance or dimming). It is shown experimentally that: (1) mislocation of target disappearance is smaller than mislocation when the target is dimmed three times; (2) the distance at which the eyes move after the target is darkened does not influence localization. The data disprove possible influence of "overtracking" on localization. They are in favour of the hypothesis about the dependence of localization on stimulus intensity.
