形式思维障碍(FTD)在临床上表现为言语混乱,但对其语言特性的研究却很少。我们研究了思维干扰如何与名词短语(NP)的使用和句子结构的复杂性所表达的语言指称功能相关。我们使用漫画描述任务从 30 名精神分裂症患者 (SZ)、15 名中度或重度 FTD (SZ + FTD) 和 15 名轻微或无 FTD (SZ−FTD) 的参与者以及 15 名 SZ 患者的一级亲属 (FDR) 和 15 名神经典型对照 (NC) 中获取语言样本。我们预测,NP 的正常指称使用中的异常(细分为确定的和不定的 NP)将识别 FTD;此外,FTD 还与语言复杂性的降低有关,具体是通过嵌入子句和语法从属的数量来衡量的。 SZ + FTD 的参与者比 NC 产生更多的参考异常,并且产生的明确 NP 最少,而 FDR 产生最多,因此也与 NC 不同。当参考异常根据发生的 NP 类型进行分类时,SZ + FTD 组在明确的 NP 中产生的异常多于 NC。句法错误并不能区分不同群体,但 SZ + FTD 组的句法复杂性明显低于非 SZ 组。探索性回归分析表明,确定的 NP 的产生区分了两个 SZ 组。这些结果表明,FTD 可以通过特定的语法模式进行识别,这为检测、干预和神经生物学研究提供了新的目标。
Formal thought disorder (FTD) is clinically manifested as disorganized speech, but there have been only few investigations of its linguistic properties. We examined how disturbance of thought may relate to the referential function of language as expressed in the use of noun phrases (NPs) and the complexity of sentence structures. We used a comic strip description task to elicit language samples from 30 participants with schizophrenia (SZ), 15 with moderate or severe FTD (SZ + FTD), and 15 minimal or no FTD (SZ−FTD), as well as 15 first-degree relatives of people with SZ (FDRs) and 15 neurotypical controls (NC). We predicted that anomalies in the normal referential use of NPs, sub-divided into definite and indefinite NPs, would identify FTD; and also that FTD would also be linked to reduced linguistic complexity as specifically measured by the number of embedded clauses and of grammatical dependents. Participants with SZ + FTD produced more referential anomalies than NC and produced the fewest definite NPs, while FDRs produced the most and thus also differed from NC. When referential anomalies were classed according to the NP type in which they occurred, the SZ + FTD group produced more anomalies in definite NPs than NC. Syntactic errors did not distinguish groups, but the SZ + FTD group exhibited significantly less syntactic complexity than non-SZ groups. Exploratory regression analyses suggested that production of definite NPs distinguished the two SZ groups. These results demonstrate that FTD can be identified in specific grammatical patterns which provide new targets for detection, intervention, and neurobiological studies.
