We are often told to pay attention to what our mothers tell us. Most of us enjoy listening to our mothers speaking. Scientists at Stanford University, US have found that compared to other people’s voices, our brains react strongly to our mother’s voices.

The scientists examined 24 children aged 7 to 12 and asked their mothers as well as two mothers whose children were not studied to record three nonsense words.“In this age period,  most children have good language skills. We didn’t want to use words that had meaning because that would have involved(涉及) many different parts in the brain,”said Professor Menon.

The children’s brains were scanned while they listened to the nonsense-word recordings, produced by their own mother and other mothers. Even from very short recordings, less than a second long, the children could make sure of their own mother’s voice with greater than 97 percent accuracy(正确率). Hearing their mother’s voice makes many parts of children’s brains more active, including those about positive emotion and social communication.
