title: Diazepam and self or externally paced letter matching tasks.
abstract: 1. Sixteen human volunteers were administered 5mg of valium or placebo on 2 visits to the laboratory. 2. Their performance in a letter matching task was studied when it was self-paced and when externally-paced by the experimenter. 3. Self-paced performance was affected by the diazepam especially in letter matches by name. 4. This supported Mirsky and Kornetsky's conclusion (1964) rather than Frowein and Sanders (1978) recent findings.
