Passage 31
学霸导读 科学家发现“经过门口”的这一动作会影响人们的记忆，神奇的“门口效应”到底是怎么一回事？
It’s a school day morning. You are dressing yourself in the bedroom. At the same time, you are thinking about taking your schoolbag from the living room. But when you walk through your bedroom door and into the living room, you suddenly forget w 1 you are there and just don’t know what to do.
Most people would think they have a poor m 2 . But scientists believe that the act of walking through doorways makes them forget things. They call it the “doorway effect”.
The scientists from the University of Notre Dame in the U.S. did an e 3 . They placed several objects into two rooms. The students had to put an object from Room A into a shoebox and then carried it to Room B through a doorway. In Room B, they exchanged it for another object and brought it back to Room A in the shoebox. Then the students were asked to do the same things w 4 crossing through a doorway.
During the period of time, the scientists would randomly ask the students which object was in their shoebox at the moment. The scientists found their answers were slower and less c 5 when they walked through a doorway and into a new room.
“A doorway is just like a boundary （ 分界线 ） in the mind，” the lead scientist Gabriel Radavansky told Scientif ic American. Setting “boundaries” in our minds can cause us to forget things e 6 . For example， when you walk into the living room， your brain thinks the act of getting your schoolbag has already been “done” and it moves on.
Is there a way to s 7 the “doorway effect”? Writing down what you need before going into another room might be helpful.
