Introduction
My research focuses on the onset and maintenance of psychosis. We developed TECS, a Stroop-based software to assess the activation of referential ideas, delusional or not, confirming their motivational basis. We refine measures of negative symptoms in adolescents and young adults, identifying mediating factors such as complex emotions, belonging, and detachment. A related line explores body concerns, referential ideas, and other pathological processes.

Introduction
Ideas of reference (IR) are frequent in psychopathology, mainly in psychotic disorders. The frequency of IR and preoccupation about them are related to the psychotic dimension, and to a lesser extent, to negative or emotional disorganized dimensions. Aberrant salience (AS), has been proposed as an indicator of the onset of psychosis, p...

The role of these systems...
