Even if your five-year-old kid does not know what money can buy for him or her, the moment he or she gets to know the value of it, chances are the knowledge may make him or her less philanthropic in nature, says an interesting research.In other words, the act of handling money makes young children work harder and give less. This effect was observed in children who lacked the concrete knowledge of money’s purpose and persisted despite the denomination of the money.

It produces good outcomes in terms of concentration and effort but bad outcomes when it comes to helping, taking, and donating.” said professor Kathleen Vohs from the University of Minnesota and co-author of the study.For this, the researchers conducted five experiments and one study involving 550 children (ages three-six) in Poland and the US. In one experiment, the children were asked to either sort money or buttons before completing a challenging puzzle. The paper is forthcoming in the journal Psychological Science.
