• It requires an understanding how an individual interpret social interactions.
• However, schizophrenics can interpret these interactions in a disorted manner (leading to paranoia)
• Making it harder for DRs to understand what they’re experiencing.

Question 5

Answer 5

1. Allows clinicians to observe patient interactions/reactions in a simulated controlled social setting (which can help identify specfic symptoms like paranoia)
2. Expose patients to stimuli that may trigger symptoms (hallucinations) in a controlled way.
3. Evaluate cognitive impairments associated with schizophrenia.

controlled + standardised = minimisied inaccuracies associated with face to face daignosis.
(the assumption is that if VR can be used to better understand those without schziophrenia it can be used to develop a better understanding of schizophrenia
