Holcombe:LoOrHighLevel

Is your visual phenomenon/threshold determined at a low level or a high level?

-Show something is high-level by  &bull; not affected much by equiluminance, 2nd-order &bull; dichoptic same &bull; not affected much by contrast or other image degradation &bull; caused by motion but not retinal motion (smooth pursuit induced?) &bull; benefits from mobile computation even with large steps &bull; masking? &bull; has both temporal freq and rps limit? &bull; temp freq limit doesn't follow from temporal phase limit at lower temporal freqs (in other words, it's a temporal crowding limit) &bull; temp freq limit reflects low-level or can be gated by color attention? (e.g. Fujisaki & NIshida A/V)
