Seventy-six children who stuttered, aged 5-12, were administered tests of motor coordination, psycholinguistic abilities, and stuttering severity. A factor analysis of 19 selected variables yielded four statistically useful factors that implicate linguistic integration, oral motor ability, and auditory processing abilities as underlying components among the sample population. These components are assumed to affect a child's threshold for fluency and to permit stuttering development. Stuttering frequency or severity was not related to any of the four factors. The implications for diagnosing and treating children who stutter are discussed.
76名年龄在5至12岁之间的口吃儿童接受了运动协调、心理语言能力和口吃严重程度测试。对19个选定变量进行的因素分析产生了四个具有统计学意义的有用因素，这些因素表明语言整合、口腔运动能力和听觉处理能力是样本人群中的潜在组成部分。这些组成部分被认为会影响儿童的流畅性阈值，并导致口吃的发展。口吃频率或严重程度与这四个因素中的任何一个均无关联。文中讨论了对口吃儿童进行诊断和治疗的意义。
