Severly and profoundly mentally retarded persons (SMRs) show a weak responsiveness to enviromental stimuli.In this project, three auditory evoked potentials ( auditory brainstem response, middle latency response, and slow vertex response ) and some variables of psychophysiological functions ( heart rate,respiration rate, eye movement,and so on ) were studied in SMRs.The main results were as follows: 1. Many SMRs had the higher auditory threshold (above 30dB nHL), as determineded by the threshold of ABR (wave V). 2. Peak latencies of evoked potentials and ABR I-V interpeak latencies were prolonged in many SMRs. 3. The phasic descending HR responses to stimuli in living situation increased with development. 4. In the SMRs who didn't show phasic HR responses, tonic HR responses(extention of HR change) to enviroment were observed. 5. The HR activity to enviroment couldn't be observed in persons who had sever brainstem dysfunction.

重度和极重度弱智者（SMRs）对环境刺激的反应性较弱，本研究对SMRs的三种听觉诱发电位（听觉脑干反应、中潜伏期反应和慢顶反应）和一些心理生理功能变量（心率、呼吸率、眼动等）进行了研究，主要结果如下：1.许多SMR具有更高的听阈（高于30 dB nHL），这由ABR（V波）的阈值决定。2.诱发电位峰潜伏期和ABR I-V峰间潜伏期延长。3.对生活情境刺激的时相性HR下降反应随发育而增强。4.在没有出现时相性HR反应的SMR中，观察到对环境的紧张性HR反应（HR变化的延长）。5.重度脑干功能障碍者不能观察到对环境的HR活动。
