Lingual vibrotactile thresholds were used to demonstrate an interaction between the lingual senses of vibrotaction and temperture. Thresholds were obtained on 10 Ss from the anterior midline of the lingual dorsum at a frequency of 250 Hz. Five temperature conditions were tested ranging in 10 degrees C steps from 17 degrees C to 57 degrees C. Thresholds were obtained before and after the introduction of the temperature stimuli. Comparison of mean pre- and post-experimental thresholds demonstrated that temperature is a determining factor in lingual vibrotactile threshold values. The data indicated that systematic variation from normal body temperature resulted in corresponding decreases in lingual vibrotactile sensitivity. Diagnostic and clinical implications of this interaction were discussed.
舌部振动触觉阈值被用于证明舌部振动触觉和温度感觉之间的相互作用。在10名受试者的舌背中前部以250赫兹的频率获取阈值。测试了五种温度条件，温度以10摄氏度为步长，从17摄氏度到57摄氏度。在引入温度刺激之前和之后获取阈值。对实验前和实验后平均阈值的比较表明，温度是舌部振动触觉阈值的一个决定因素。数据表明，与正常体温的系统性差异导致舌部振动触觉敏感性相应降低。讨论了这种相互作用的诊断和临床意义。
