科萨科夫健忘症患者和酒精控制患者被要求回忆同一类别的九个名词的连续列表。预期的逐步下降的回忆被逆转的类别转移的第五个列表的控制，但不是健忘症。在第五个列表中，上下文的变化（改变单词和背景的颜色）导致了健忘症患者的表现改善，而不是控制组。然而，如果这是一个序列中的第二个转变（在试验九中），或者如果他们被告知要期待转变，那么健忘症患者在类别转变时确实表现出“从主动干扰中释放”。这些发现将健忘症患者已知的对主动干扰的脆弱性与对现有线索的使用障碍联系起来，以将新材料与旧材料分开-除非这些线索额外突出。这种困难在学习和提取过程中都可能发生。
Korsakoff amnesic and alcoholic control patients were asked to recall successive lists of nine nouns of the same category. The expected progressive decrease in recall was reversed by a category shift on the fifth list for controls but not for amnesics. A context shift on the fifth list (changed color of words and background) led to improved performance by amnesics but not by controls. However, amnesics did show "release from proactive interference" at category shift if it was the second shift in a sequence (on trial nine) or if they were told to expect the shift. These findings relate amnesics' known vulnerability to proactive interference to an impaired use of available cues to segregate new from old material--unless the cues are made additionally salient. This difficulty could operate both during learning and at retrieval.
