People often have trouble distinguishing between history and maturation. History comes from external or “out there” events and occurs around the same time that the IV is administered (think of a historical or current event), while maturation reflects changes that occur within subjects as the result of the passage of time (think natural growth and development that comes with maturing). Sometimes it helps to see similar concepts side by side so you can identify the distinguishing factors. Check out the comparison chart below for a visual reference.
