Abstract
AbstractSchizotypy is associated with poor emotion regulation that is thought to contribute to the development of psychotic symptoms and to indicate a predisposition to schizophrenia. Having focused primarily on the relationship between schizotypy and explicit emotion regulation, existing studies have, until now, neglected to acknowledge the potentially important role of implicit emotion regulation. Our aim in the current study was to investigate implicit emotion regulation deficits in schizotypy. To this end, we used a newly developed Priming-Identification (PI) ERP paradigm, consisting of a priming phase and an emotion identification phase, to test 30 individuals with schizotypy and 30 healthy controls while also acquiring EEG data. During the priming phase, we aimed to manipulate emotion regulation goals (i.e., to bring about an intended emotional state) by presenting a category of words related to emotion regulation alongside a category of control words. Associated brain responses occurring during the subsequent stage were indexed according to three ERP components: N170, early posterior negativity (EPN) and late positive potential (LPP). Results showed that, in the control group, priming words associated with emotion regulation led to enhancements in the early N170 amplitude and the middle EPN during expression identification. The same pattern was not observed in the schizotypy group. In summary, our results suggest the presence of deficits in the early and middle stages of the implicit emotion regulation process among individuals with high schizotypal traits.
