自动和努力的记忆过程进行了评估，在2个会议，在主题设计涉及酒精挑战和无酒精条件。自由回忆90个单词的列表衡量了费力的处理。估计词频，从同一个列表中自动测量处理。急性中毒被假设为减少努力，但不是自动记忆过程。健康男性志愿者（n= 36）完成了2个条件，间隔1周。呈现频率影响自由回忆和频率估计，随着呈现频率的增加，这两个措施增加。自由回忆显着低于在酒精比无酒精条件下，但频率估计没有差异的影响。数据显示，酒精挑战使志愿者的自动记忆过程和努力记忆过程分离。作者讨论了潜在的神经生物学底物，可能解释酒精的选择性破坏努力，言语，情节记忆处理。
Automatic and effortful memory processes were evaluated in a 2-session, within-subjects design involving an alcohol challenge and a no-alcohol condition. Free recall of a 90-word list measured effortful processing. Estimation of word frequency from the same list measured automatic processing. Acute intoxication was hypothesized to diminish effortful but not automatic memory processes. Healthy, male volunteers (n= 36) completed the 2 conditions 1 week apart. Presentation frequency influenced both free recall and frequency estimation, with both measures increasing as presentation frequency increased. Free recall was significantly lower in the alcohol than in the no-alcohol condition, but frequency estimation was not differentially affected. The data showed that an alcohol challenge dissociated automatic and effortful memory processes in volunteers. The authors discuss potential neurobiological substrates that may account for alcohol's selective disruption of effortful, verbal, episodic memory processing.
