They theorize that the reason is that the longer targets have more retinal motion opposite the pursuit, so this cancels the efference copy to eliminate the extrapolation. An alternative account is that longer exposure improves the integration with spatiotopically stationary landmarks, reducing the reliance on the retinotopic code. Since this does not help for targets moving with the eyes, would have to posit that stabilization thanks to landmarks doesn't happen with moving targets. But this seems unlikely.

Biphasic Neuron Extrap
A-V flash lag
foveo fugal/petal biases

Temporal variability might arise from:

  1. Position shifting that increases with velocity, with constant noise added to velocity
  2. Uncertainty in *when* the judgment was supposed to be made
  3. For any effects caused by afferent latency (Hazelhoff?), variability in latency

deValois stands out as only temporal bias with spatial variability. Then why doesn't Cai and Frohlich have temporal bias? Only easy explanation would be the possibly-greater blur of the deValois stimuli, so we have to check that. Increasing eccentricity would also increase the spatial uncertainty[48] perhaps allowing temporal to manifest
