Speed can go up as well as down at low contrast: implications for models of motion perception.
Thompson P, Brooks K, Hammett ST. Thompson P, et al. Vision Res. 2006 Mar;46(6-7):782-6. doi: 10.1016/j.visres.2005.08.005. Epub 2005 Sep 19. Vision Res. 2006. PMID: 16171842 Free article.
It is well-known that reducing the contrast of a slow moving stimulus reduces its apparent speed. [Thompson, P. (1982). Perceived rate of movement depends on contrast. Vision Research, 22, 377-380.] report of this finding also suggested that at speeds above 8 cycles …

Perceptual distortions of speed at low luminance: evidence inconsistent with a Bayesian account of speed encoding.
Hammett ST, Champion RA, Thompson PG, Morland AB. Hammett ST, et al. Vision Res. 2007 Feb;47(4):564-8. doi: 10.1016/j.visres.2006.08.013. Epub 2006 Sep 29. Vision Res. 2007. PMID: 17011014 Free article.
We show here that the results can be accounted for by an extension to a simple ratio model of speed encoding [Hammett, S. T., Champion, R. A., Morland, A. & Thompson, P. G. (2005). A ratio model of perceived speed in the human visual system. ...
