口腔感觉功能对于一系列摄取的成功表现是必不可少的。尽管对物体大小的感知在决定操纵程度方面很重要，但有证据表明，人们并不总是准确地感知口腔中物体的大小。本研究旨在探讨影响口腔内物体大小知觉的因素。23名健康青年志愿者盲测插入口腔的圆柱体的大小，并从参考组中进行识别。横截面直径为10~14 mm，间隙为1 mm，有3种不同的温度(5、36、50℃)。记录感知大小，并评估与实际大小的差异。还测量了识别所需的时间，并在性别和温度之间进行了比较。结果表明，大小错觉的方向受辨认所需时间的显著影响。长操作导致高估，短操作导致低估对象大小，而与温度和大小无关。性别是影响口腔大小知觉的另一个因素。在这项实验中，女性参与者的高估比率比男性参与者低，尽管参与者的数量有限。因此，我们得出结论，为了检测影响口腔内大小知觉的其他因素，调节口腔操作时间是必不可少的。
Oral sensory function is essential for the successful performance of a range of ingestion. Although the perception of object size is important in determining the degree of manipulation, evidence suggests that people does not always perceive the size of the object in oral cavity accurately. The purpose of this study was to investigate the factors affecting the intraoral perception of object size. Twenty‐three healthy young volunteers detected the size of cylinders inserted into oral cavity blindly and identified it from the reference set. The diameter of cross section varied from 10 to 14 mm in a gap of 1 mm and had three different temperatures (5, 36, 50 °C) in each. The perceived size was recorded, and the difference with the actual size was assessed. The required time for identification was also measured and compared between gender and between temperatures. The results demonstrated that the direction of size illusion was significantly affected by the required time for identification. Long manipulation led to overestimation, and short manipulation led to underestimation of object size irrespective of temperature and size. Gender was the other factor affecting intraoral size perception. The rate of overestimation was low in female participants comparing with male participants in this experiment, although the number of participants was limited. We therefore concluded that in order to detect the other factors affecting intraoral size perception, regulating oral manipulation time is indispensable.
