“…The CDI provides a measure of communication impairment (Docherty, 2005) and rates the number of speech unclarities, with an unclarity being any speech passage in which the meaning is sufficiently unclear to impair the overall meaning of the speech passage. The CDI was developed as an extension of a previous measure of unclear referents in speech that has been used frequently in previous schizophrenia research (Rochester & Martin, 1979) and the CDI has been used frequently in schizophrenia research as a measure of disordered speech (Kerns & Berenbaum, 2003; Docherty, 2005). It is associated with older measures of disorganized speech such as the Thought, Language, and Communication (TLC) scale (Docherty et al, 1996).…”

Previous schizophrenia research suggests poor cognitive control is associated with schizophrenia speech symptoms. However, cognitive control is a broad construct. Two important cognitive control components are poor goal maintenance and poor verbal working memory storage. In the current research, people with schizophrenia (n = 45) performed three cognitive tasks that varied in their goal maintenance and verbal working memory storage demands. Speech symptoms were assessed using clinical rating scales, ratings of disorganized speech from typed transcripts, and self-reported disorganization. Overall, alogia was associated with both goal maintenance and verbal working memory tasks. Objectively rated disorganized speech was associated with poor goal maintenance and with a task that included both goal maintenance and verbal working memory storage demands. In contrast, self-reported disorganization was unrelated to either amount of objectively rated disorganized speech or to cognitive control task performance, instead being associated with negative mood symptoms. Overall, our results suggest that alogia is associated with both poor goal maintenance and poor verbal working memory storage and that disorganized speech is associated with poor goal maintenance. In addition, patients’ own assessment of their disorganization is related to negative mood, but perhaps not to objective disorganized speech or to cognitive control task performance.

“…In schizophrenia, failures to establish coherence (clinically referred to as tangentiality and derailment) (Andreasen, 1979b; Earle-Boyer et al ., 1986; Mazumdar et al ., 1995) as well as referential cohesion (Docherty et al ., 1996; Rochester & Martin, 1979), during communication are amongst the most common clinical phenomena described. Despite these observations, there has been surprisingly little ERP work examining how schizophrenia patients build up meaning over more than one sentence.…”

“…Nonetheless, given the robust evidence that schizophrenia patients, even those without thought disorder, fail to construct cohesive reference links during language production (Docherty et al, 1996; Rochester & Martin, 1979), patients might not fare so well when the referent is ambiguous (e.g. “Jack and Bill went to the store.…”

What can Event-related Potentials tell us about language, and perhaps even thought, in schizophrenia?

Disturbances of thought and language are fundamental to schizophrenia. Cognitive behavioral and electrophysiological research has implicated problems in two distinct neurocognitive mechanisms: abnormalities in the structure and function of semantic memory, and abnormalities in combining and integrating words together to build up sentence and discourse structure. This review discusses recent electrophysiological evidence suggesting that these two deficits are not completely distinct, but rather that language impairment in schizophrenia results from a dysfunctional interaction between these systems in an effort to build up higher-order meaning. Moreover, whereas language abnormalities are more pronounced in patients with positive thought disorder, they manifest themselves in all patients when increased demands are placed on the comprehension system. Further investigation of language dysfunction may also provide insights into other aspects of psychotic thought.

“…Social process words have been indicated as predictors of total symptoms and metacognition in schizophrenia as well (Minor et al, in press). Finally, individuals with schizophrenia show differences in use of pronouns, identifying referents non-verbally when possible and using pronouns without the support needed to identify their referents (Rochester & Martin, 1979), as well as frequently referring to themselves during prolonged speech (Hoffman et al, 1985). …”

Lexical Characteristics of Emotional Narratives in Schizophrenia

Prior research has suggested that complexity of speech, speech rate, use of emotion words, and use of pronouns are all potential indicators of important clinical components of schizophrenia, but little research has examined the relationships of these disturbances to cognitive variables impaired in schizophrenia, including social cognition. The current study examined these lexical differences to better characterize the cognitive substrates of speech disturbances in schizophrenia. Brief narratives of individuals with schizophrenia (n = 42) and non-clinical controls (n = 48) were compared according to their lexical characteristics, and these were examined for relationships to social cognition and real-world functioning. Significant differences between the groups were found in words per sentence (related to functioning, but not negative symptoms) as well as pronoun use (related to attributional style and theory of mind). Additionally, lexical characteristics effectively distinguished between individuals with schizophrenia from non-clinical controls. Language disturbances in schizophrenia appear related to social cognition impairments, real-world functioning, and are a robust indicator of clinical status.
