Did you know that infants as young as 6 months old, have a rudimentary understanding of number? When babies hear two voices they will look for two people and when they hear three voices they will look for three people. This was discovered in a study that presented infants with pictures of two and three people. When the infants heard two voices, they looked at the picture with two people on it and when the infants heard three voices, they looked at the picture with three people on it.
Fascinating! We have always believed that human beings are hard-wired for language from birth and before. Perhaps, we need to rethink our ideas about baby brains and math.
