  • Title: Computational neurobiology of the flash-lag effect.
    Author: Baldo MV, Caticha N.
    Journal: Vision Res; 2005 Sep; 45(20):2620-30. PubMed ID: 15993457.
    Abstract:
    In the flash-lag effect (FLE) a moving object is perceived ahead of a stationary stimulus flashed in spatial alignment. Several explanations have been proposed to account for the FLE and its dependence on a variety of psychophysical attributes. Here, we show that a simple feed-forward network reproduces the standard FLE and several related manifestations, such as its modulation by stimulus luminance, trajectory, priming, and spatial predictability. A minimal set of elements, based on plausible neuronal mechanisms, yields a unified account of these visual illusions and possibly other perceptual phenomena.
