Do female mice learn a maze faster than male mice? You build two mazes from cardboard: a classic maze and a T-maze. Five male and five female mice each run the classic maze five times while you record their fastest time. The next day, you use the T-maze to test paw preference. Each mouse chooses to turn left or right to reach a sunflower seed. You repeat the test five times per mouse. Female mice completed the classic maze faster. They also showed a right-paw preference, while most male mice favored their left paw.
