A sample of 'automatic speech' (counting from 1 to 10) was tape-recorded and the times taken up by phonation and pauses measured. In four healthy volunteers, both phonation times and pause times remained constant over a period of two months. In four moderately depressed patients, with no history of manic illness and with no obvious clinical signs of motor retardation, the pause times were significantly elongated while the patients were depressed compared to pause times measured after recovery. The phonation times were constant throughout the period of observation (4-6 months). Other tests for motor retardation (tapping time; Nurses' rating scale; Hamilton Retardation Scores) did not give consistent results. It is concluded that the simple test described here may reveal a degree of motor retardation in cases where other tests fail to do so.
采集了一段“自动言语”样本（从1数到10）并进行录音，同时测量发声和停顿所占用的时间。在4名健康志愿者中，发声时间和停顿时间在两个月内保持恒定。在4名中度抑郁症患者中，他们没有躁狂病史且没有明显的运动迟缓临床体征，与康复后测量的停顿时间相比，患者抑郁时停顿时间显著延长。在整个观察期（4 - 6个月）内发声时间保持恒定。其他运动迟缓测试（敲击时间；护士评定量表；汉密尔顿迟缓评分）结果并不一致。得出的结论是，此处描述的简单测试可能会在其他测试未能发现的情况下揭示一定程度的运动迟缓。
