The flicker-fusion threshold was determined in 76 patients who complained of depression and who were diagnosed as suffering from either schizophrenia or depression. It was found to be lowered in schizophrenia and lowered further in depression as compared with 28 healthy volunteers. The differences between the three groups were all highly significant with P less than 0.0005 in each case. The flicker-fusion threshold was found to be lowered by intravenous chlorpromazine and raised by intravenous amitriptyline, so it is unlikely that these differences were due to medication that the patients had been taking.
对76名主诉抑郁且被诊断为患有精神分裂症或抑郁症的患者测定了闪光融合阈值。结果发现，与28名健康志愿者相比，精神分裂症患者的闪光融合阈值降低，抑郁症患者的闪光融合阈值进一步降低。三组之间的差异均具有高度显著性，每组的P值均小于0.0005。静脉注射氯丙嗪可使闪光融合阈值降低，静脉注射阿米替林可使其升高，因此这些差异不太可能是由于患者之前服用的药物所致。
