Do you ever walk out of a room with an idea in your head, only to discover moments later that it's gone? 1f so, don't worry: it's a very common experience. 【小题1】

The problem is often caused by "event boundaries". 【小题2】They make you believe that a particular mental task is over.

Tests have proved that we're much more forgetful when we move from one location to another.【小题3】It's because anything that seems like the end of a task — closing a study book, finishing a phone call, taking a cake out of the oven — can have the same effect. Within seconds, much information in your mind has disappeared.

【小题4】First, stop telling your brain that its work is done. This can be as simple as leaving a book open instead of putting it back on the shelf. Second, create clues to carry with you across any unavoidable event boundary. Notice when these end-points are coming up, and spend a moment improving your memory.

If possible, say the key points out loud: the job you're walking off to do in the next room, for example, or the plans you've just made on the phone. We actually know memory depends on imagery.   【小题5】

Every day you're faced with event boundaries that may restrict your recall. But by avoiding them when you can, and disguising them when you can’t, you'll find that much less of your learning gets lost.
