Abstract：
BACKGROUND:Many social processes such as emotion recognition are severely impaired in patients with schizophrenia. While basic auditory processing seems to play a key role in identifying emotions, research in this field is limited due to the lack of proper assessment batteries. Many of the widely accepted tests utilize actors to portray certain emotions-these batteries are less ecologically and face valid. METHODS:This study utilized a newly developed auditory emotion recognition test that contained natural stimuli from spontaneous displays of emotions to assess 28 patients with schizophrenia and 16 healthy controls. RESULTS:The results indicate that the newly developed test, referred to as the INTONATION Test, is more sensitive to the emotion recognition deficits in patients with schizophrenia than previously used measures. The correlations of the INTONATION Test measures with basic auditory processes were similar to established tests of auditory emotion. Particular emotion sub scores from the INTONTATION test, such as happiness, demonstrated the strongest correlations with specific auditory processing skills, such as formant discrimination and sinusoidal amplitude modulation detection (SAM60). CONCLUSIONS:The results from this study indicate that auditory emotion recognition impairments are more pronounced in patients with schizophrenia when perceiving authentic displays of emotion. Understanding these deficits could help specify the nature of auditory emotion recognition deficits in patients with schizophrenia and those at risk.
