Dimensions of Speech and Language Disturbance in Psychosis and Computational Linguistic Markers

Much of our understanding of psychosis behavioral phenotypes occurs through the medium of speech – either through the content of what our patients report, or through how it is spoken. Speech is considered the observable surface phenomena that reveal, in part, the shrouded thoughts of the inner “mind.” We will first review historical and current understandings of speech and language disturbance in psychosis, then examine data for latent factors, and finally relate these clinical phenomena to distinct computational linguistic features.
