In a replication of Frumkin et al. we investigated the hypothesis that hypnosis may facilitate a shift in brain hemispheric dominance, as assessed by right-ear dominance shifts in a dichotic listening paradigm. Eight low, 13 medium, and 8 high hypnotizables, as assessed by the Stanford Hypnotic Susceptibility Scale, Form C, were given the Berlin et al. dichotic tape during two waking conditions and following an alert hypnotic induction. Results contradicted Frumkin et al. In contrast, low hypnotizables showed a significant reduction in right-ear dominance, suggestive of greater participation of the right cerebral hemisphere following hypnotic induction. Highs and mediums did not change. Discussion centers around procedural differences between the two studies (particularly type of hypnotic induction and instructions to attend to one or both ears) and the possible influence of relaxation/anxiety levels upon lateral shifts in cerebral function.
在对弗鲁姆金等人研究的一项重复实验中，我们调查了如下假设：催眠可能会促进大脑半球优势的转变，这一转变通过双耳分听范式中右耳优势的转变来评估。根据斯坦福催眠易感性量表C型，对8名低催眠易感性者、13名中等催眠易感性者和8名高催眠易感性者，在两种清醒状态下以及经过一次警觉性催眠诱导后，播放了柏林等人的双耳分听录音带。结果与弗鲁姆金等人的研究相反。相比之下，低催眠易感性者的右耳优势显著降低，这表明催眠诱导后右脑半球的参与度更高。高催眠易感性者和中等催眠易感性者则没有变化。讨论集中在两项研究之间的程序差异（特别是催眠诱导的类型以及关注一只耳朵或两只耳朵的指示）以及放松/焦虑水平对大脑功能横向转变的可能影响。
