In an investigation of the role of cognitive effort in hypnotic responding, high and low hypnotizable participants produced emotionally neutral imagery in response to effortful versus effortless hypnotic suggestions. Heart-rate increase served as an objective index of cognitive effort, and subjective ratings of imagery vividness, absorption, effort, and control were collected. Compared to lows, high hypnotizable participants experienced their imagery as more vivid and absorbing, yet their heart rates indicated no higher level of cognitive effort than lows. Compared to effortless wording, effortful wording of suggestions increased cognitive effort in lows, as indexed by heart-rate increase, but had no effect on the effort expended by highs. Ratings of subjective control were strongly correlated with subjective effort for lows but unrelated for highs. These results support the dissociated-control theory of hypnosis rather than the dissociated-experience or social-cognitive theories.
在一项关于认知努力在催眠反应中作用的调查中，高催眠易感性和低催眠易感性的参与者根据费力与不费力的催眠暗示产生情绪中性的意象。心率增加作为认知努力的客观指标，并收集了意象生动性、专注度、努力程度和控制感的主观评分。与低催眠易感性参与者相比，高催眠易感性参与者觉得他们的意象更生动、更能引人专注，然而他们的心率显示出其认知努力水平并不比低催眠易感性参与者更高。与暗示的不费力措辞相比，暗示的费力措辞增加了低催眠易感性参与者的认知努力，以心率增加为指标，但对高催眠易感性参与者所付出的努力没有影响。主观控制感评分与低催眠易感性参与者的主观努力密切相关，但与高催眠易感性参与者无关。这些结果支持了催眠的分离控制理论，而非分离体验理论或社会认知理论。
