The cry sounds of 12 well-nourished and 12 malnourished male infants were compared using behavioral and acoustic measures. The cry of the malnourished infant had an initial longer sound, higher pitch, lower amplitude, more arrhythmia, and a longer latency to the next cry sound than the cry of the well-nourished infant. The similarity betweenthe cry of the malnourished infant and the cry of the brain-damaged infant suggested tha malnutrition may affect the regulatory function of the central nervous system. This hypothesis was supported by additional findings which showed that the abnormal cry patterns in the malnourished infants were associated with a low-level orienting response to a pure tone stimulus as measured by the magnitude of heart-rate deceleration.
采用行为学和声学测量方法，对12名营养良好的男婴和12名营养不良的男婴的哭声进行了比较。营养不良婴儿的哭声与营养良好婴儿的哭声相比，起始音更长、音调更高、振幅更低、心律不齐更多，且下次哭声的延迟时间更长。营养不良婴儿的哭声与脑损伤婴儿的哭声之间的相似性表明，营养不良可能会影响中枢神经系统的调节功能。这一假设得到了其他研究结果的支持，这些结果表明，营养不良婴儿的异常哭声模式与通过心率减速幅度测量的对纯音刺激的低水平定向反应有关。
