Adults learn to identify pain in babies’ cries

Résumé

Because the expression of pain in babies’ cries is based on universal acoustic features, it is assumed that adult listeners should be able to detect when a crying baby is experiencing pain. We report that detecting that a baby’s cry expresses pain actually requires learning through experience. Our psychoacoustic experiments reveal that adults with no experience of caring for babies are unable to identify whether a baby’s cry is a pain cry induced by vaccination or a mild discomfort cry recorded during a bath, even when they are familiar with the discomfort cries from this particular baby. In contrast, people with prior experience of babies — parents or professional caregivers — identify a familiar baby’s pain cries without having heard these cries before. Parents of very young children are even able to identify the pain cries of a baby who is completely unfamiliar to them. Exposure through caregiving and/or parenting thus shapes the auditory and cognitive abilities involved in decoding the information conveyed by the baby’s communication signals.
