Health Tip: Baby Steps
Ever wonder at what age infants recognize that tools can make difficult or impossible tasks easier?
The psychology department at the University of Dundee in Scotland conducted a simple test with a number of infants. Researchers placed a towel on the floor, and put a toy on the far end of the towel. They wanted to see how old each infant had to be before he or she was smart enough to pull on the towel in order to get the toy.
As reported in the journal Developmental Behavior, infants discovered the use of tools earlier than you might think. In fact, most learned they could get the toy by pulling on the towel by the age of 6 months.
