It has been suggested that formal thought disorder, the incoherent speech of schizophrenia, may involve a language disturbance among other abnormalities, or even be a form of dysphasia. Six patients with and seven without formal thought disorder were evaluated on an aphasia test battery. Spontaneous speech was also analysed using Brief Syntactic Analysis. Poor performance on the aphasia test battery was found to be associated with general intellectual impairment but not with formal thought disorder. Naming was preserved in both groups. Patients with formal thought disorder, but not those without, produced semantic errors in their spontaneous speech, and these were unrelated to general intellectual status. The disorder of language in formal thought disorder thus appears to be one of expressive semantic abnormality, which, however, spares naming. Further analysis of two intellectually preserved patients suggested that formal thought disorder may be associated with an additional difficulty in constructing an appropriate model for generating one's own speech.
有人提出，形式思维障碍，即精神分裂症患者的言语不连贯，可能在其他异常情况中涉及语言障碍，甚至是一种失语症形式。对6名有形式思维障碍和7名无形式思维障碍的患者进行了失语症测试。还使用简短句法分析对自发言语进行了分析。结果发现，失语症测试表现不佳与一般智力损害有关，但与形式思维障碍无关。两组患者的命名能力均得以保留。有形式思维障碍的患者在自发言语中出现语义错误，而无形式思维障碍的患者则未出现，且这些语义错误与一般智力状况无关。因此，形式思维障碍中的语言障碍似乎是一种表达性语义异常，但不影响命名。对两名智力正常的患者进行的进一步分析表明，形式思维障碍可能与构建生成自身言语的适当模型时存在的额外困难有关。
