摘要: The effects of alcohol and sleep deprivation on choice reaction time (RT) as a function stimulus intensity, quality, response compatibility were investigated. Fifty-four male subjects assigned to one three levels (0.00, 0.07, or 0.10 BAC), two (0 24 h). Stimulus varied (high low), with RTs identified according task. Significant main each the variables present in baseline analysis, low-level conditions producing longer RTs. Alcohol produced an overall slowing RT. combination both treatments led larger increases RT for low quality. Sleep increased high intensity. but only when not deprived. These results imply higher risk degraded conditions, e.g., driving settings visibility at night.
