Can posthypnotic suggestion (PHS) enhance cognitive abilities? The authors tested behaviorally and with event-related potentials (ERP) if sequential learning (SL), the ability to learn statistical regularities, can be enhanced with PHS. Thirty adults were assessed with the Stanford Hypnotic Susceptibility Scale (Form C) and an auditory SL task. Before this task, half the sample received a PHS to enhance SL, and the other half received the same suggestion under normal waking state. Response times and ERPs indicated a strong effect of PHS. Compared to the control group, PHS inverted, attenuated, or left unaffected the response time SL effect in low, medium, and high hypnotizability participants, respectively. These results suggest that PHS cannot be used to enhance SL.
催眠后暗示(PHS)能提高认知能力吗?作者通过行为测试和事件相关电位(ERP)来检验,顺序学习(SL),即学习统计规律的能力,是否可以通过PHS得到提高。30名成年人接受了斯坦福催眠易感性量表(C型)和一项听觉顺序学习任务的评估。在这项任务之前,一半的样本接受了增强顺序学习的催眠后暗示,另一半在正常清醒状态下接受了相同的暗示。反应时间和ERP表明催眠后暗示有显著效果。与对照组相比,催眠后暗示分别使低、中、高催眠易感性参与者的反应时间顺序学习效应发生反转、减弱或未受影响。这些结果表明,催眠后暗示不能用于增强顺序学习。
