This study tested the prediction that dissociative tendencies modulate the impact of a hypnotic induction on cognitive control in different subtypes of highly suggestible individuals. Low suggestible (LS), low dissociative highly suggestible (LDHS), and high dissociative highly suggestible (HDHS) participants completed the Stroop color-naming task in control and hypnosis conditions. The magnitude of conflict adaptation (faster response times on incongruent trials preceded by an incongruent trial than those preceded by a congruent trial) was used as a measure of cognitive control. LS and LDHS participants displayed marginally superior up-regulation of cognitive control following a hypnotic induction, whereas HDHS participants' performance declined. These findings indicate that dissociative tendencies modulate the influence of a hypnotic induction on cognitive control in high hypnotic suggestibility and suggest that HS individuals are comprised of distinct subtypes with dissimilar cognitive profiles.
这项研究检验了这样一种假设,即分离倾向调节催眠诱导对不同类型高暗示性个体认知控制的影响。低暗示性(LS)、低分离性高暗示性(LDHS)和高分离性高暗示性(HDHS)参与者在控制和催眠条件下完成斯特鲁普颜色命名任务。冲突适应的幅度(在不一致的试验之前出现不一致的试验比在一致的试验之前出现的试验的反应时间更快)被用作认知控制的度量。LS 和 LDHS 参与者在催眠诱导后表现出认知控制的适度上调,而 HDHS 参与者的表现则下降。这些发现表明,分离倾向调节催眠诱导对高催眠暗示性认知控制的影响,并表明 HS 个体由具有不同认知特征的不同亚型组成。
