Ninety subjects (45 males, 45 females) were given 0.0, 0.5, or 1.0 ml/kg body weight of 190-proof ethanol and tested for chance-level presence/absence detection thresholds with energy-masked presentations of traffic signs and blank inputs. Alcohol produced higher blood alcohol concentration (BAC) levels, and higher detection threshold durations, for females than for males. These results indicate that alcohol influences precortical visual processing and that the influence is greater for females than for males. The higher bioavailability of alcohol in women is likely due to less gastric oxidation of ethanol in women than in men.
90名受试者（45名男性，45名女性）分别接受了每千克体重0.0、0.5或1.0毫升的95度乙醇，并通过对交通标志的能量掩蔽呈现和空白输入来测试其偶然水平的存在/缺失检测阈值。酒精使女性的血液酒精浓度（BAC）水平更高，检测阈值持续时间也更长，高于男性。这些结果表明，酒精会影响皮层前视觉处理，且对女性的影响大于男性。女性体内酒精的生物利用度较高，可能是因为女性体内乙醇的胃氧化作用比男性少。
