Habituation in psychiatric patients to repeated stimuli has typically been described in connection with the measurement of the skin conductance orienting response. Here EEG power spectra of acute schizophrenic patients and normals to 4 trials of an acoustic stimulation were examined for evidence of habituation. In response to stimulation the alpha EEG reactivity was less distinct in schizophrenics than in normals. This is in agreement with the theory of hypovariability or hyperstability of the EEG in schizophrenics. Signs of habituation in acute schizophrenics were clearer in fast beta frequencies of the parietal leads.
精神病患者对重复刺激的习惯化通常是在与皮肤电导率定向反应测量相关的情况下进行描述的。在此，对急性精神分裂症患者和正常人在4次听觉刺激试验中的脑电图功率谱进行了检查，以寻找习惯化的证据。在对刺激的反应中，精神分裂症患者脑电图α波的反应性比正常人不明显。这与精神分裂症患者脑电图低变异性或高稳定性的理论相符。急性精神分裂症患者在顶叶导联的快β频率中习惯化的迹象更明显。
