健忘症患者和对照受试者接受了一项基于计算机的认知技能任务的培训。最初,健忘症患者的改善速度是正常的。一组单独的正常受试者在每次试验中从计算机收到随机反馈时,并没有改善这项任务。一个月后,当在这项任务上进行额外的培训时,对照组的表现好于健忘症患者。两组中的任何一组都几乎没有迁移到表面外观不同但需要相同认知策略的第二项技能任务。问卷数据显示,对照组受试者,而不是健忘症患者,获得了关于执行任务所需策略的陈述性知识。研究结果表明,在健忘症患者中,认知技能学习最初可以以正常的速度进行,这可能是因为陈述性知识在训练早期对表现没有实质性的贡献。然而,陈述性知识可能会在以后的训练中做出重要贡献,因此可能会使正常受试者比健忘症患者更有优势。
Amnesic patients and control subjects were trained on a computer-based cognitive skill task. Initially, the amnesic patients improved at a normal rate. A separate group of normal subjects did not improve on the task when they received random feedback from the computer on each trial. One month later, when additional training on the task was given, the control subjects performed better than the amnesic patients. There was little if any transfer by either group to a second skill task that had a different surface appearance but which required the identical cognitive strategy. Questionnaire data showed that the control subjects, but not the amnesic patients, acquired declarative knowledge about the strategy needed to perform the task. The findings show that cognitive skill learning can initially proceed at a normal rate in amnesia, presumably because declarative knowledge makes no material contribution to performance early in training. However, declarative knowledge may make an important contribution later in training and may therefore give normal subjects an advantage over amnesic patients.
