在允许不受限制地获得酒精的条件下（N = 18）以及需要执行简单的操作任务才能获得酒精和香烟的条件下（N = 8），对酗酒者的饮酒模式进行了比较。工作相关的酒精获取的特点是 3-6 天的饮酒期和 2-3 天的相对禁欲工作期之间交替，这通常与部分戒断症状和体征有关。不受限制地饮酒（32 盎司/天）的受试者在 8-15 天的饮酒期内保持了稳定的血液酒精水平（150 至 200 毫克/100 毫升）。两组中都没有受试者喝完所有可用的酒精。尽管每天从食物和酒精中摄入的热量平均在 4000 至 5000 卡路里之间，但受试者的体重几乎没有波动。讨论了饮酒模式在决定其行为和生物效应方面所起的作用。
Drinking patterns of alcoholics were compared under conditions which allowed unrestricted access to alcohol (N= 18), and where it was necessary to perform a simple operant task in order to obtain both alcohol and cigarettes (N= 8). Work-contingent alcohol acquisition was characterized by alternations between drinking episodes of 3-6 days, and relatively abstinent work periods of 2-3 days which were usually associated with partial withdrawal signs and symptoms. Subjects given unrestricted access to alcohol (32 ounces/day) maintained stable levels of blood alcohol (between 150 and 200 mg/100 ml) over drinking periods of 8-15 days. No subject in either group drank all the alcohol available. Subjects showed little fluctuation in body weight, even though daily caloric intake from food and alcohol averaged between 4000 and 5000 calories per day. The role which the pattern of alcohol consumption plays in determining its behavioral and biologic effects is discussed.
