Emotion recognition in unaffected first-degree relatives of individuals with first-episode schizophrenia

摘要

Objective: Impairments in recognising negative emotions are found in individuals with first-episode and chronic schizophrenia and also in those at ultra-high risk for the illness. Whether these impairments are an endophenotype for schizophrenia is unclear. To examine the heritability of emotion recognition, the aim of this study was to examine whether facial and prosody emotion recognition deficits, particularly for negative emotions, are also present in unaffected first-degree relatives of people with schizophrenia.
