innate mathematical ability

A new study suggests that monkeys have a basic grasp of probabilities.

Where does our ability to do abstract maths come from? A new study sheds some fascinating light on the question.

Human reasoning is biased and illogical. At least that's what a huge body of psychological research seems to show. But now a psychological scientist from the University of Toulouse in France has come up with a new theory: that logical and probabilistic thinking is an intuitive part of decision making, only its conclusions often lose out to heuristic considerations.

People as well as animals are born with a sense for numbers. But is this inborn number sense related to mathematical ability? A new study suggests that it is.
