Quinal barbitone, dextro‐amphetamine and placebo were compared with respect to changes produced in perceived duration in ninety normal subjects. A method was employed which permitted quantitative derivation of a subject's concept of one second , pre‐drug, 30 min. post‐drug and 60 min. post‐drug. The following findings were obtained. (1) A significant decrease in the clock‐measured value of the apparent second with the ingestion of dextro‐amphetamine. (2) A significant increase in the clock‐measured value of the apparent second with the ingestion of quinal barbitone. (3) A trend toward increase in the apparent second with placebo. These findings were discussed in terms of earlier reports and a theoretical framework was offered.
