本研究使用一个组成过程模型，研究了酗酒者和社区对照组受试者在获取新情境约束（如情景）信息时的认知过程。特别令人感兴趣的是，酗酒者在获取信息的效率方面是否低于对照组，以及在认知效率方面是否存在性别与群体的相互作用。酗酒者（n= 16女性；n= 22男性）和社区控制者（n= 21女性；n= 21男性）参加了一系列学习任务，该任务由三个12项单词列表组成。采用串行学习任务的标准管理协议。在效率措施方面，组间[F(1,75) = 8.51,p= 0.005]和性别间[F(1,75) = 4.05,p= 0.048]存在显著差异。组间存在交互作用[F(1,75) = 7.73,p= 0.007]。Duncan多范围比较显示，酗酒女性明显低于对照组女性，但与男性对照组和酗酒者相当。这些数据与其他研究一致，揭示了认知效率对酒精相关影响的敏感性，并将先前的研究结果扩展到涉及情景学习任务的任务中。
Using a component processes model, the current study examined the cognitive processes of alcoholic and community control subjects engaged in the acquisition of new context‐bound (e.g., episodic) information. Of particular interest was whether alcoholics were inferior to controls in the efficiency with which information was acquired and whether there was a gender × group interaction in cognitive efficiency. Alcoholic (n= 16 females;n= 22 males) and community control (n= 21 females;n= 21 males) subjects participated in a serial learning task that consisted of three 12‐item word lists. Standard administration protocols for serial learning tasks were used. On efficiency measures, there were significant differences between groups [F(1,75) = 8.51,p= 0.005] and sexes [F(1,75) = 4.05,p= 0.048]. There was also a group × sex interaction [F(1,75) = 7.73,p= 0.007]. Duncan multiple‐range comparisons revealed alcoholic females to be significantly inferior to control females, but equivalent to male controls and alcoholics. These data are consistent with other studies revealing the sensitivity of cognitive efficiency to alcohol‐related effects and extend previous findings to tasks involving episodic learning tasks.
