Emotions in Schizophrenia and Bipolar Disorders: a Common Vulnerability?

The initial aim of the project was to gain an understanding of the comprehension of "language-oriented" emotions among schizophrenic and bipolar patients. By "language-oriented" emotions, the investigators mean the emotions that are conveyed by means of language, whether through the emotional valence of the words, the expression of an emotional state or emotional prosody. Although they involve different diagnostic categories, schizophrenic and bipolar disorders nevertheless share a number of symptoms, in particular in the emotional sphere, and do so to such an extent that the question of whether there may, at the clinical, cognitive and etiopathogenic levels, exist a continuum between these disorders is frequently raised. Taking this hypothesis of a clinical continuum as our starting point, the investigators explored the understanding of emotions contextualized by language in these two clinical populations, namely patients exhibiting schizophrenic and bipolar disorders. To these populations, the investigators also added the dimension of vulnerability in the form of non-clinical participants varying in terms of their traits of schizotypy and hypomania, thus orienting this project toward the early identification of cognitive-emotional markers and possibly also their prevention.
