Abstract:
The ability to perceive emotions is imperative for successful interpersonal functioning. The present study examined the neural characteristics of emotional prosody perception with an exploratory event-related potential analysis. Participants were 59 healthy individuals who completed a discrimination task presenting 120 semantically neutral word pairs from five prosody conditions (happy/happy, angry/angry, neutral/neutral, angry/happy, happy/angry). The task required participants to determine whether words in the pair were spoken in same or different emotional prosody. Reflective of an initial processing stage, the word 1 N1 component was found to have greatest amplitude in parietal regions of the hemispheres, and was largest for emotional compared to neutral stimuli, indicating detection of emotion features. A second processing stage, represented by word 1 P2, showed similar topographic effects; however, amplitude was largest for happy in the left hemisphere while angry was largest in the right, illustrating differentiation of emotions. At the third processing stage, word 1 N3 amplitude was largest in frontal regions, indicating later cognitive processing occurs in the frontal cortex. N3 was largest for happy, which had lowest accuracy compared to angry and neutral. The present results support Schirmer and Kotz's (2006) model of vocal emotion perception because they elucidated the function and ERP components by reflecting three primary stages of emotional prosody perception, controlling for semantic influence.
