High-hypnotizable subjects (n = 18) were superior to low-hypnotizable subjects (n = 18) in the extent of pain reduction produced by hypnotic analgesia and by a stress-inoculation procedure. However, stress inoculation but not hypnotic analgesia impaired performance on a cognitively demanding task that competed with pain reduction for cognitive resources. This outcome implies that hypnotic analgesia occurs with little or no cognitive effort to reduce pain and challenges the social psychological model of hypnosis. The findings are also inconsistent with the notion of dissociated experience, which proposes that pain and the cognitive efforts to reduce it are cut off from consciousness by an amnesialike barrier. However, the results do support the notion of dissociated control, which proposes that suggestions for hypnotic analgesia directly activate pain reduction and thereby avert the need for cognitive strategies to reduce pain.
高催眠易感性受试者（n = 18）在催眠镇痛和应激接种程序产生的疼痛减轻程度上优于低催眠易感性受试者（n = 18）。然而，应激接种而非催眠镇痛会损害一项需要认知资源且与减轻疼痛相竞争的认知要求较高任务的表现。这一结果意味着催眠镇痛在减轻疼痛时几乎不需要或只需极少的认知努力，这对催眠的社会心理模型提出了挑战。这些发现也与分离体验的概念不一致，分离体验概念提出疼痛及其减轻疼痛的认知努力通过类似遗忘的屏障与意识相分离。然而，结果确实支持分离控制的概念，该概念提出催眠镇痛的建议直接激活疼痛减轻，从而避免了采用认知策略来减轻疼痛的必要性。
