Abstract:

Thirty young men were randomly assigned in equal numbers to one of the following groups placebo lactose, secobarbital 100 mg, or d-amphetamine 10 mg. The drugs or placebo were administered in capsules in a double-blind procedure. Tests were scheduled 1, 2, and 4 hours after capsule ingestion all tests were conducted inside a Stille-Werner rotator and were in total darkness with the exception of the illuminated tracking display. During angular acceleration, secobarbital subjects made significantly more tracking errors and had significantly more vestibular nystagmus than both the control and the d-amphetamine groups for all post-drug sessions. These findings agree with previous studies of alcohol effects depressant drugs may have little or no deleterious influence on tracking performance in static environments, but may produce marked performance degradation during angular motion.
