Emotional language is all right: Emotional prosody reduces hemispheric asymmetry for linguistic processing
2016
ABSTRACTIn an influential paper, Bryden and MacRae [(1989). Dichotic laterality effects obtained with emotional words. Neuropsychiatry, Neuropsychology, and Behavioral Neurology, 1, 171–176] introduced a dichotic listening task that allowed for the assessment of linguistic and prosodic processing asymmetries using the same stimuli. The task produces a robust right ear advantage (REA) for linguistic processing (identifying a target word), and a left ear advantage for emotional processing (identifying a target prosody). Here, we adapted this paradigm to determine whether and how the presence of emotional prosody might modulate hemispheric asymmetry for linguistic processing. Participants monitored for a target word among dichotic stimuli consisting of two different words, but spoken in the same emotional prosody—neutral, angry, happy, sad, or fearful. A strong REA was observed when the words were spoken in neutral prosody, which was attenuated for all the emotional prosodies. There were no differences in th...
