“…Minor and Cohen (2010) observed that those with schizotypy exhibited elevated disorganized speech compared to the non-schizotypy group across negative and positive valence conditions-but no increase in affective reactivity. In a separate study, Minor and Cohen (2012) failed to observe increased affective reactivity. The influence of affect on speech production has been examined in two studies in schizotypy, both of which reported no…”

Diminished productivity and elevated disorganization have been detected in the speech of individuals with schizotypy. However, the underlying mechanisms for these disruptions are not well understood. Separate lines of research suggest potential contributions from cognitive and affective systems. In this study, disorganized speech and speech production were examined in speech samples generated by schizotypy (n = 47) and non-schizotypy (n = 51) groups by assessing "reactivity" (i.e., a change in experimental compared with baseline conditions) across baseline, affective, and dual-task (i.e., cognitive) conditions. Relationships with social functioning were also examined within each group. Three key findings emerged: 1) compared to the non-schizotypy group, those with schizotypy exhibited diminished speech production in the affective condition and affective reactivity was observed; 2) the schizotypy group displayed greater levels of disorganized speech in dual-task conditions and cognitive reactivity was observed; and 3) affective reactivity for disorganized speech was linked to worse social functioning within the schizotypy group. This study provides evidence that cognitive and affective systems are uniquely involved in separate characteristics of speech in schizotypy. At this stage, cognitive systems appear to have a specific role in the organization of speech, whereas affective systems are more heavily involved in speech production. Regarding the association between affective reactivity and social functioning, previous research has demonstrated individuals highly reactive to emotional stimuli carry additional risk for conversion to psychosis. Future research identifying a subset with schizotypy who demonstrate affective reactivity could lead to a better understanding of links between schizotypy and future psychosis symptoms.

“…However, attempted replication of these findings has yielded mixed support both across-and within-schizotypy studies (Cohen et al, 2012;Cohen et al, 2014;Minor et al, 2011;Minor and Cohen, 2012), and indicate that disorganized and diminished speech are more likely to be observed when certain underlying mechanisms are activated.…”

“…However, one limitation is that no behavioral measures were utilized to assess psychotic symptoms. Although clinician-rated instruments are commonly used in schizophrenia studies, behaviorallybased instruments have demonstrated promise as assessment tools, particularly in identifying disorganized symptoms (Docherty, 2012;Minor and Cohen, 2012). The lack of a patient control group is another limitation of this study.…”

“…category exemplars) and thus, may not truly reflect coherence as is relates to conversational discourse. It is possible that average cosines and vector length values are not sensitive enough to detect decreased semantic coherence under the constraints of this task; whereas previous studies that have tested semantic coherence in schizotypy (Minor et al, 2011;Minor and Cohen, 2012) and clinical high risk samples (Bedi et al, 2015) have used natural speech. Another limitation of the verbal fluency task is that there are a wide array of approaches one could use to complete this task.…”

Technological advancements have led to the development of automated methods for assessing semantic coherence in psychiatric populations. Latent Semantic Analysis (LSA) is an automated method that has been used to quantify semantic coherence in schizophrenia-spectrum disorders. The current study examined whether: 1) Semantic coherence reductions extended to psychometrically-defined schizotypy and 2) Greater cognitive load further reduces semantic coherence. LSA was applied to responses generated during category fluency tasks in baseline and cognitive load conditions. Significant differences between schizotypy and non-schizotypy groups were not observed. Findings suggest that semantic coherence may be relatively preserved at this point on the schizophrenia-spectrum.
