Examination of habituation to disgust-related stimuli has received limited experimental investigation. In this study, 38 undergraduates were divided into two groups. The vomit-blood (VB) group was first exposed to a realistic approximation of vomit and allowed to habituate to this stimulus, while the blood-vomit (BV) group was first allowed to habituate to a realistic approximation of blood. Following the habituation phase, each group underwent a short exposure to the unexposed stimuli (blood in the VB group, vomit in the BV group). Physiological and self-report assessments were collected during exposure. Self-report habituation was observed for both groups. In addition, only muscle tension at the levator labii and heart rate in the VB group demonstrated significant changes that could be interpreted as habituation. Consistent with previous literature, muscle tension at the levator labii appeared to be a unique indicator of disgust responding. Implications and suggestions for future research are discussed.

暴露对多种厌恶指数上的习惯化泛化的影响。

对与厌恶相关的刺激的习惯化的研究已经受到有限的实验研究。在这项研究中，将38名本科生分为两组。呕吐血（VB）组首先要经受现实的近似呕吐，并习惯于这种刺激，而血呕吐（BV）组首先要适应于现实的近似血液。在适应阶段之后，每组短时间暴露于未暴露的刺激下（VB组为血液，BV组为呕吐）。在暴露期间收集生理和自我报告评估。两组均观察到自我报告的习惯。此外，VB组中仅提肌上的肌张力和心率显示出明显的变化，可以解释为习惯。与以前的文献一致，上提肌唇肌张力似乎是反感反应的唯一指标。讨论了对未来研究的启示和建议。
