We are all born with a number of instinctive physical reactions, things we do automatically, 
which are called primitive reflexes. One of the most interesting is called "grasp reflex". If you 
touch the palm of a baby's hand, the fingers will close around, whatever object is doing the 
touching. The baby's grip is so strong that if a baby grasps a rod with both hands, it can be lifted 
right off the ground. Some psychologists think that this goes back to our evolutionary past when

disappears at about six months of age.
