在言语类或意志性非言语的口头运动任务中，表现率的测量经常被用来推断神经运动障碍患者的发音率异常。本研究的目的是探讨言语速率测量与非言语言语运动行为之间的结构关系。共有130名神经运动障碍患者和130名健康受试者参与了这项研究。收集了口头阅读（语音）、快速音节重复（类语音）和快速单个发音器运动（非语音）的速率数据。作者使用因子分析来确定不同的比率变量是否反映相同或不同的结构。行为数据最恰当地捕获的测量模型中，不同的任务类型加载到单独的潜在变量。口头运动表现率的数据表明，语音任务和口头运动任务，如快速音节重复或重复单个发音器运动，测量的是不同的特征。
Measures of performance rates in speech-like or volitional nonspeech oral motor tasks are frequently used to draw inferences about articulation rate abnormalities in patients with neurologic movement disorders. The study objective was to investigate the structural relationship between rate measures of speech and of oral motor behaviors different from speech. A total of 130 patients with neurologic movement disorders and 130 healthy subjects participated in the study. Rate data was collected for oral reading (speech), rapid syllable repetition (speech-like), and rapid single articulator movements (nonspeech). The authors used factor analysis to determine whether the different rate variables reflect the same or distinct constructs. The behavioral data were most appropriately captured by a measurement model in which the different task types loaded onto separate latent variables. The data on oral motor performance rates show that speech tasks and oral motor tasks such as rapid syllable repetition or repetitive single articulator movements measure separate traits.
