Selected subjects from a group of first onset schizophrenics (aged under 30 years) were taken from a previous study and placed in one of two groups depending upon whether they had exclusively positive symptoms (n = 9) or a mixture of positive and negative symptoms (n = 9). Their linguistic profiles were compared with those of a group of controls (n = 10) matched for educational attainment and parental social class. Both groups of schizophrenics had significantly lower integrity scores, suggesting that they made more syntactic and semantic errors. Those patients who presented with negative symptoms tended to have speech of lower syntactic complexity than the other two groups, although the difference just failed to reach statistical significance. It is suggested that syntactic and semantic errors are state dependent features associated with positive symptoms, whereas low syntactic complexity may be a more enduring feature associated with the presence of negative symptoms.
一组首次发病的精神分裂症患者（年龄在30岁以下）中的选定受试者取自先前的一项研究，并根据他们是否仅有阳性症状（n = 9）或阳性和阴性症状混合（n = 9）分为两组。将他们的语言特征与一组在教育程度和父母社会阶层方面相匹配的对照组（n = 10）的语言特征进行比较。两组精神分裂症患者的完整性得分均显著较低，这表明他们犯了更多的句法和语义错误。那些出现阴性症状的患者的言语句法复杂性往往低于其他两组，尽管这种差异刚刚未达到统计学显著性。有人认为，句法和语义错误是与阳性症状相关的状态依赖性特征，而低句法复杂性可能是与阴性症状存在相关的更持久的特征。
