Olfactory hallucinations (smelling odors that are not present) are intrusive and disruptive yet challenging to investigate because they cannot be produced on demand. In this study, the authors attempted to model olfactory hallucinations using hypnotic suggestions. We gave some subjects a suggestion to smell an odor in the absence of a real odor (positive hallucination) and gave others a suggestion to smell nothing in the presence of a real odor (negative hallucination). High hypnotizable individuals who received the positive hallucination reported intense smells whereas those who received the negative hallucination reported a reduction in intensity. These suggestions also influenced later recall about frequency of odor presentation. Findings are discussed in terms of reality monitoring and differences between positive and negative hallucinations.
嗅觉幻觉（闻到并不存在的气味）具有侵扰性且会造成干扰，但因其无法按需产生，所以研究起来颇具挑战性。在本研究中，作者尝试通过催眠暗示来模拟嗅觉幻觉。我们向一些受试者暗示在没有真实气味的情况下闻到某种气味（阳性幻觉），而向另一些受试者暗示在有真实气味的情况下闻不到任何气味（阴性幻觉）。接受阳性幻觉暗示的高催眠易感性个体报告称闻到了浓烈气味，而接受阴性幻觉暗示的个体则报告气味强度有所降低。这些暗示还影响了之后对气味呈现频率的回忆。我们从现实监测以及阳性和阴性幻觉之间的差异方面对研究结果进行了讨论。
