The loss of position constancy during pursuit eye movements

, : The loss of position constancy during pursuit eye movements. Vision Research 18(1): 55-62

There may be 2 factors resposible for the position constancy losses during pursuit in human subjects. The first is the under-registration of velocity. It accounts for the loss of constancy when the perception of background objects is determined by the relationship between eye movement and image movement information. The 2nd factor is the displacement of the background relative to the tracked target, when the background and target are adjacent, which may account for the very substantial losses of constancy which can occur during smooth pursuit. The failure to make the distinction between object-relational (exocentric) cues to motion and eye movement-retinal image displacement information (egocentric) may lead to the erroneous conclusion that smooth eye movement information is not involved in the perception of the motion and stability of the background.
