Changes in oculocentric visual direction induced by the recalibration of saccades.
The association between perceived visual direction and retinal location has been considered to be specified at birth and unmodifiable. We found that small changes occurred in the visual direction associated with a peripheral retinal location when the amplitudes of saccadic eye movements to a target imaged at that location were experimentally increased or decreased. This result indicates that at least limited plasticity exists in the perceptual representation of retinal location.
