Retroactive Visual Masking: Effects of Test Flash Duration on the Masking Interval.
Luminance, Mask interval, Bright summation model
Digital Object Identifier (DOI)
The interval at which a dim test flash (TF) is masked by a succeeding bright flash (BF) was determined for two subjects at 6 levels of TF luminance (log mlam—1.8, 1.5, 1-1, 0.8, 0.5) and 5 levels of TF duration (log msec—1.3, 1.2, 1-0, 0.7, 0.5). BF luminance was 3.8 log mlam, and 1.0 log msec. The masking interval when measured from the onset of the Tf to the onset of the BF was found to be a power function of a weighted combination of TF luminance and duration. Luminance was somewhat more effective than duration in determining the masking interval. The implications of these results for the bright summation model are discussed.
