title: Perceptual latencies are shorter for motion towards the fovea than for motion away.
abstract: Subjects had to align a brief test flash with a peripheral steady reference target during ocular pursuit, or with a moving reference target during steady eye fixation. The performance was determined by the direction of movement, of the reference target image on the retina--towards or away from fovea. The data are explained by the hypothesis that the passage of a retinal locus by a moving target image is experienced faster when the image moves foveopetally, regardless of whether the passage is caused by real target movement or by ocular pursuit.
