Abstract: | For nonmetacontrast (disk-disk) masking, if the outer diameter of the mask equals that of an annulus which produces typical metacontrast functions, U- and W-shaped functions will be obtained if (1) the stimuli are viewed dichoptically and monoptically, respectively. and (2) the mask is no more than about 10 times the energy (luminance x duration) of the target. As this energy ratio is approached, both types of functions become monotonic. These shapes suggest that interactions at different visual-pathway loci may he mapped by visual masking functions. |
