OBSERVATIONS ON THE EFFECT OF CIGARETTE SMOKING ON THE FUSION FREQUENCY OF FLICKER

Abstract

Studies were made on 20 subjects on the effect of cigarette smoking on the fusion frequency of flicker. Following a period of abstinence from smoking, such as overnight, the first cigarette smoked causes an immediate increase in the fusion frequency of flicker. With continued smoking this effect becomes reduced. The elevation in fusion frequency of flicker resulting from smoking a cigarette is due to the nicotine content of the cigarette tobacco. The smoking habits of the individual should be taken into account in fusion frequency of flicker measurement.
