The purpose of this study was to determine through psychophysical comparison of scaling data whether speech naturalness judgments of stutterers and nonstutterers from audiovisual recordings form a prothetic or a metathetic continuum. Comparison of direct magnitude estimation and equal-appearing interval scale data indicated that speech naturalness forms a metathetic continuum when observers judge audiovisual recordings, suggesting that either scaling procedure is valid for the quantification of this dimension. Ease of use, an existing body of comparative data from different clinics, and somewhat better reliability favor the interval scaling procedure.
本研究的目的是通过对缩放数据进行心理物理学比较，来确定口吃者和非口吃者对视听记录的言语自然度判断是形成了一个量值量表连续体还是一个类别量表连续体。直接数量估计和等距量表数据的比较表明，当观察者判断视听记录时，言语自然度形成了一个类别量表连续体，这表明两种缩放程序对于该维度的量化都是有效的。使用的便利性、来自不同诊所的现有比较数据以及相对更好的可靠性都有利于采用等距量表程序。
