Abstract
A double-blind crossover study investigated the effects of marihuana on human visual information processing. A tachistoscopic paradigm was used and no marihuana effect was shown on the critical stimulus duration, a measure of stimulus intake. The visual backward masking data are compatible with a marihuana induced slowness of information processing from labile unconscious iconic memory to more permanent memory processes. Reports of marihuana''s effects on perception and early information processing are discussed.This publication has 14 references indexed in Scilit:
