Complain like you mean it! How prosody conveys suffering even about innocuous events

When complaining, speakers can use their voice to convey a feeling of pain, even when describing innocuous events. Rapid detection of emotive and identity features of the voice may constrain how the semantic content of complaints is processed, as indexed by N400 and P600 effects evoked by the final, pain-related word. Twenty-six participants listened to statements describing painful and innocuous events expressed in a neutral or complaining voice, produced by ingroup and outgroup accented speakers. Participants evaluated how hurt the speaker felt under EEG monitoring. Principal Component Analysis of Event-Related Potentials from the final word onset demonstrated N400 and P600 increases when complainers described innocuous vs. painful events in a neutral voice, but these effects were altered when utterances were expressed in a complaining voice. Independent of prosody, N400 amplitudes increased for complaints spoken in outgroup vs. ingroup accents. Results demonstrate that prosody and accent constrain the processing of spoken complaints as proposed in a parallel-constraint-satisfaction model.

Automated summary

When complaining, the voice can convey a feeling of pain, even when describing harmless events. The processing of complaints is influenced by the emotional features of the voice, as shown by the N400 and P600 effects. Prosody and accent also play a role in the processing of spoken complaints, according to the parallel-constraint-satisfaction model proposed in this study.
