Simultaneous motion contrast: Velocity, sensitivity and depth response

  author={P. D. Tynan and Robert Sekuler},

A center and surround of spatially random dots were used to study the effect of surround motion on the center’s (1) perceived velocity, (2) perceived depth and (3) visibility. The velocity of the surround influenced the center’s velocity and depth in similar, complex ways. But surround speed had no effect on the luminance detection threshold of the center dots. Results with these dependent measures bear on theories of motion perception and on processing in other sensory domains. When all the… CONTINUE READING
