Like a snow-covered mountain peak, accompanied by a cliff suddenly breaking down, toddlers suddenly burst into a series of new words after a long time of accumulation, in the effect called " snowball ". During this period, it seemed that children's vocabulary exploded after only one night.

A new study explains that nothing is miraculous here: babies start to wander after they have mastered enough words to overcome difficult words. That's basically the snowball effect.

This explanation, published today in the journal Science, is much simpler than the scientists' speculation that some special mechanisms of the brain need to participate in order to activate the bomb of this term.

Psychology professor Bob McMurray from the University of Iowa, USA, thinks what makes parents surprised in reality is the result of many quiet accruals little by little as they begin their journey to learn 60,000 since to adulthood.

If McMurray is right, this finding will be helpful for parents who are being " attacked " by technology ads that can enhance a child's language. He said that the key here is simply to talk and read to children a lot.

" Children are absorbing everything, " he said. "You can use the word 'lucky' for children to hear. And they will have to touch hundreds, even thousands of times to understand what" luck "is, so why not start it early? ".
