Wissenschaftler haben die Sprache und den Inhalt der Traum-Berichte von Schizophrenen und Menschen mit bipolarer Störung „kartographiert“. Fascinating Stuff und der letzte Satz ist Gold: „The Freudian notion that 'dreams are the royal road to the unconscious' is clinically useful, after all.“
In search of quantitative insight into the structure of psychotic speech, we investigated speech graph attributes (SGA) in patients with schizophrenia, bipolar disorder type I, and non-psychotic controls as they reported waking and dream contents.
Schizophrenic subjects spoke with reduced connectivity, in tight correlation with negative and cognitive symptoms measured by standard psychometric scales. Bipolar and control subjects were undistinguishable by waking reports, but in dream reports bipolar subjects showed significantly less connectivity.
