About this trial

This study aims to explore whether the observation of complex visual objects can help improve social cognition in people living with psychotic disorders. Social cognition refers to the ability to understand what others think, feel, or intend, and plays a key role in social relationships and daily interactions.

Main questions this study aims to answer:

* Does dyadic exposure to complex visual objects improve mental state attribution, as measured by the Faux Pas Test? * Does the intervention enhance related domains of social cognition, including implicit intention inference (Hinting Task), interpretation of complex interactions (Movie for the Assessment of Social Cognition, MASC), and reduction of hostile attribution biases (Ambiguous Intentions Hostility Questionnaire, AIHQ)? * Are improvements maintained after one month, and do patients who receive the intervention later (waitlist group) show the same benefits once exposed?
