What did you have for dinner Tuesday night of last week? If someone （ask）you that question Wednesday morning, you would （possible）have had no problem recalling what you had for dinner the night before．
But as days pass, the memories of all the other meals you （eat）since then start to interfere（干扰）with your memory of that one particular meal．This is a good example of psychologists call the interference theory of forgetting．Forgetting is the result of （vary）memories interfering with one another．The more similar two or more events are one another, the more likely interference will occur．
Getting rid of interference altogether is impossible, but there are a few things you can do to minimize its effects．One of the best things you can do is rehearse（排练）new information in order to better commit it to memory．In fact, many experts recommend overlearning important information, involves rehearsing the material over and over again until it can be reproduced perfectly with no errors．Another strategy for fighting interference is to switch up your routine and avoid （study）similar material back to back．Sleep also plays an essential role in memory （form）．Sleeping after you learn something new is efficient way to turn new memories into lasting ones．
