We are often told to pay attention to what our mothers tell us. Scientists have found that our brains greatly prefer the voices of our own mothers.
Scientists at Stanford University recently studied this. They scanned (扫描) children’s brains while they were listening to different sounds, including their mothers’ voices. They found that 97 percent of the time, children could recognize (识别) their mothers’ voices at once.
Hearing their mothers’ voices makes children’s brains more active. We usually just use one part of our brains to deal with sounds when we hear something. But when we hear our mothers’ voices, many parts of the brain start to work as well.
Why do we reply so strongly to our mothers’ voices? On one hand, when we are still in the womb (子宫) before we’re born, we hear our mothers talking. This makes us feel comfortable. On the other hand, mothers teach us talk and social skills by repeating words again and again. This way, when mother’s sound is heard again, more attention is paid to it.
Some sounds are necessary for our life and they bring us pleasure. But mothers’ voices are different and they make us feel comfortable. We will feel very relaxed when we hear our own mothers’ voices.
