Vocal and forearm EMGs were recorded from 19 hallucinating and 22 nonhallucinating psychiatric inpatients. A microphone placed close to the lips was used to detect subvocal speech. The subjects' EMG and subvocal responses to pre-recorded statements were also assessed. Subjects who experienced hallucinations during assessment were asked to estimate the frequency of their hallucinations and rate phenomenological of their most recent hallucination. Results essentially replicated studies that found increased vocal potentials in hallucinators, but also showed that these increased potentials were nonsignificant when nonvocal measures are included in the statistical analysis. Subvocal speech and coincident increases in vocal EMG with reports of hallucinations, and with reports of pre-recorded statements, were not found. A significant negative correlation was found between the mean vocal potential of hallucinators and the perceived location of their most recent hallucination. The pre-recorded statements were generally perceived to be louder, clearer and more outside the head than the most recent hallucination.
对19名有幻觉的精神科住院患者和22名无幻觉的精神科住院患者进行了声带和前臂肌电图记录。在靠近嘴唇处放置一个麦克风来检测低语。还评估了受试者对预先录制语句的肌电图和低语反应。要求在评估过程中出现幻觉的受试者估计其幻觉频率，并对其最近一次幻觉的现象学进行评分。结果基本上重复了那些发现幻觉者声带电位增加的研究，但也表明，当在统计分析中纳入非发声测量时，这些增加的电位并不显著。未发现低语以及声带肌电图与幻觉报告和预先录制语句报告同时增加的情况。发现幻觉者的平均声带电位与其最近一次幻觉的感知位置之间存在显著负相关。与最近一次幻觉相比，预先录制的语句通常被认为声音更大、更清晰，且更像是来自头部外部。
