In life, have you ever had the experience of "momentary amnesia", for example, you originally wanted to get something, and when you were preparing to do it, you suddenly forgot what you were going to do; you wanted to say something to a friend, but suddenly you couldn't remember what you just wanted to say; open the browser and suddenly forget what you just wanted to check...
Scientists have given this phenomenon a very apt name, the "doorway effect," which describes the possibility that a person entering from one door to another may suddenly forget something. Scientists have done relevant test experiments specifically for this phenomenon to explore the secrets behind the doorway effect.
The researchers divided the subjects into two groups to test the changes in their memory in the real room and the virtual room, respectively, to detect whether the "door effect" would occur. People in real rooms are asked to answer questions about them at any time while holding boxes in their hands and putting or taking out different items inside, sometimes walking back and forth in the same room, sometimes through a door. Another group of test subjects were asked to control virtual characters in video games to complete the same action instructions and questions as the previous group.
Experimental results show that whether the environment is real or virtual, people's memory will be affected after passing through the door, people's reaction will be slower, and the error rate will increase.
Psychologists point out that this has to do with the relationship between people's attention and the level of behavior. To accomplish an action, it is necessary to break it down into several levels. Usually, within a day, people's attention shifts up and down between three different levels of behavior, depending on the situation, from goals and ambitions, to plans and strategies, to the lowest level, which is specific behavior. Only then can people complete more complex actions, stepping over the needs of multiple moments, multiple locations, or multiple behaviors to piece together a clear plan.
For example, if you are an experienced driver, you are already familiar with a series of driving steps, so you can complete these actions unconsciously, at this time your attention is on the target level, you can chat with passengers while driving, but if there is an unusual situation, such as encountering a complex intersection on the road or when the engine has a strange noise, you will turn your attention to the specific matter of driving, temporarily leaving the overall situation; when the abnormality is lifted, you can continue to drive as usual. Transport passengers to their destination.
The "doorway effect" arises because we accomplish all sorts of different things. While the external environment, including the space, time, and things we are facing, is constantly changing, the internal environment, that is, our thinking and psychology, are also changing and jumping accordingly. What we want to do may be only a small part of it, and when the situation changes, it may be forgotten.
But the "doorway effect" isn't necessarily a bad thing. You can think of it as a regulatory function of the brain, just as our computers need to clean up memory regularly after a long time, and the brain also needs to delete some less important or temporary information to store more new information and remember more useful things. Scientists have also found that the doorway effect allows people to focus more on what they are doing and less susceptible to interference from other information.
