Abstract
Increment threshold of a small test probe is found to be elevated by backgrounds of a disk, bar, or luminance step. The spatial parameters that produce maximum masking are found to be essentially similar with the three types of background. The lime course of masking is also found to be similar for the disk and bar background. It is suggested that a fundamentally similar type of visual processing underlies each of the masking situations.
