Retroactive Brightness Enhancement with Brief Paired Flashes of Light
Test flash, Brighter flash, Direct magnitude-estimation
Digital Object Identifier (DOI)
The brightness of a semi-circular test flash (TF), when followed at varying intervals by a circular, brighter flash (BF), was measured by a direct magnitude-estimation technique. There was a gradual increase in the brightness of the TF as the TF-BF interval was decreased. Brightness enhancement of the TF began when the interval between onsets of the two 10 msec flashes was about 150 msec and attained a maximum between 100 and 30 msec, depending upon the TF luminance. The brightness of the TF is a power function of the TF-BF interval with a negative exponent; the dimmer the TF the higher the absolute value of the exponent. A model accounting for this phenomenon in neurophysiological terms has been proposed.
