    Department of Ophthalmology, McGill Vision Research, McGill University, Montreal, Canada
    Vision Res 39:733-45. 1999
    ..Our results were well fitted by the probability summation model and hence support the underlying stochastic independence of the three postreceptoral mechanisms...

    S J Cropper
    McGill Vision Research, Department of Ophthalmology, McGill University, Montreal, Quebec, Canada

    C L Baker
    McGill Vision Research Unit, Department of Ophthalmology, McGill University, Montreal, Quebec, Canada
    Vision Res 38:291-302. 1998
    ..This result further strengthens the dichotomy between the two kinds of motion perception, and suggests that when color vision supports motion perception it does so primarily, or perhaps entirely, via a nonlinear mechanism...

    ..Our data were fitted with the occupancy model of Allik and Tuulmets (1991, Perception & Psychophysics 49 303-314) and we found that blue-yellow stimuli have a greater 'occupancy' than red-green or achromatic stimuli...

    J Opt Soc Am A Opt Image Sci Vis 14:984-96. 1997
    ..Thus we conclude that there is no need to postulate separate mechanisms for fast and slow motion [Nature (London) 367, 268 (1994)], since a unified ratio model can explain both RG and achromatic contrast-speed dependency...
