The stability of oral and nonoral vibrotactile magnitude scales produced by the method of magnitude production was investigated for 11 adult subjects. Each subject was tested over four sessions separated by 1-wk. intervals. Data analyses included correlations across trials of power function slopes as well as individual adjustments of intensity. Analysis showed a lack of stability over time for the slope functions obtained on the thenar eminence but moderate stability for the functions obtained on the tongue. Individual adjustments on intensity showed consistently high correlations across trials and structures. It was concluded that the subjects' responses were guided by the imposed experimental variables and that each individual's scaling was not necessarily reflected by the correlations based on power function slopes established over the four trials.
采用量值产生法研究了11名成年受试者产生的口腔和非口腔振动触觉量值量表的稳定性。每位受试者在间隔1周的四个阶段接受测试。数据分析包括幂函数斜率跨试验的相关性以及强度的个体调整。分析表明,鱼际隆起处获得的斜率函数随时间缺乏稳定性,但舌部获得的函数具有中等稳定性。强度的个体调整在各试验和结构之间始终显示出高度相关性。得出的结论是,受试者的反应受施加的实验变量指导,且基于四次试验建立的幂函数斜率的相关性不一定能反映每个个体的量表。
