Abstract
Cloze analysis was used to assess the “understandability” of the spontaneous speech of a normal S who had received 9 mg. of psilocybin. This drug seemed to exert an enhancing effect within the first 1½ hr., followed quickly by a deterioration in the quality of verbal communication for about the next 2 hr.
