In an interesting Australian study researchers discovered that toddlers began to count at an earlier age than what was previously thought to be.
Researchers, from the University of Queensland, led by Prof. Virginia Slaughter, discovered that children as young as 18 months showed an understanding of math. Mastery of counting is only achieved by the age of four. Yet, according to this study, infants begin to understand numbers at one and a half years. Interestingly, researchers also discovered this ability does not show itself a little earlier on, at fifteen months old.
The study involved watching videos of six fish. Except for one, all showed wrong counting. The researchers reported that the 36 children in the study preferred to watch only the correct version.
The conclusion drawn by Dr.Slaughter and her team was that counting skills begin quite early in humans.
