Facial Emotion Processing in Patients with Schizophrenia: Study Results from Psychological Measurement to Brain Imaging?

A prominent characteristic of patients with schizophrenia is impaired social functioning ability. Positive symptoms, negative symptoms, and neurocognitive defi cits can impair their ability to function and interact in normal social environments. Patients’ inability to identify facial emotions is a major contributing factor to this dysfunction. Identifying and interpreting facial emotions are critical to social cognition, and previous behavioral studies have shown a signifi cant defi cit in facial emotion processing for them. The defi cit is category-specifi c and more substantially related to negative emotions. When studying facial emotion processing in Taiwanese patients with schizophrenia, previous studies faced two issues. First, the investigators found that Taiwanese patients cannot process facial emotions in non- Taiwanese faces as accurately as in Taiwanese faces. And second, cultural bias in assessment methods may compromise their validity.
