Factors influencing velocity coding in the human visual system

Differential velocity detection in the fovea was measured over a wide range of velocities (0.25–256°/sec), Differential thresholds were minimum (about 6%) for intermediate velocities (4–32°/sec). Velocity judgements were shown not to depend on duration judgements. The U-shaped curve relating differe...

Summary:Differential velocity detection in the fovea was measured over a wide range of velocities (0.25–256°/sec), Differential thresholds were minimum (about 6%) for intermediate velocities (4–32°/sec). Velocity judgements were shown not to depend on duration judgements. The U-shaped curve relating differential velocity detection and velocity was preserved at different background levels and different contrasts. The physiological correlates of these observations are discussed.
