The influence of stimulants, sedatives, and fatigue on tunnel vision: risk factors for driving an d piloting

摘要

A computerized task was used in two studies to examine the influence of stimu- lants, sedatives, and fatigue on single-target and divided-attention responses in different parts of the visual field. The drug effects were evaluated over time with repeated behavioral and subjective measures against ascending and descending drug levels. In the first study, 18 fully rested participants received placebo, alproazo- lam(0.5 mg), and dextroamphetamine(10 mg). Alprazolam impairs performance, whereas dextroamphetamine induces enhancement and tunnel vision.
