在针对醉酒时内部感觉变化进行辨别训练后，酗酒者似乎比非酗酒者更难以保持血液酒精含量（BAL）估计的准确性。为了确定与这一现象相关的因素，非酗酒受试者参与了一项实验，该实验研究了酗酒家族史、饮酒模式以及对酒精的行为耐受性对血液酒精含量辨别能力的影响。在基线、训练和训练后阶段都对血液酒精含量进行了估计。家族史或饮酒模式不同的受试者组在血液酒精含量估计准确性方面没有差异。然而，在训练后的血液酒精含量估计中，“耐受性低”的受试者比“耐受性高”的受试者准确得多。这一发现表明，耐受性的发展可能与无法辨别血液酒精含量有关，如果这一发现得到证实，将对病因和治疗具有重要意义。
Alcoholics seem less able than nonalcoholics to maintain blood alcohol level (BAL) estimation accuracy after discrimination training focused on changes in internal sensations during intoxication. To identify factors associated with this phenomenon, nonalcoholic subjects participated in an experiment that examined the effects of family history of alcoholism, drinking pattern, and behavioral tolerance to alcohol on BAL discrimination. Blood alcohol level estimates were made during baseline, training, and posttraining sessions. Groups of subjects differing in family history or drinking pattern did not differ in BAL estimation accuracy. "Low tolerant" subjects, however, were substantially more accurate than "high tolerant" subjects in posttraining BAL estimation. This finding suggests that the development of tolerance may relate to the inability to discriminate BAL, a finding which, if confirmed, has important causal and treatment implications.
