A、The need to exercise the memory. B、How the brain differs from other body tissues. C、The unconscious learning of a physical act

Some of the most practical lessons coming out of research in psychology are the area of memory. People ask, why can’t I remember that term from the physical chapter or the date my library books are due? Well, for a lot of people, memory may be weak, because they don’t use it enough.[26]It’s like a muscle. If you don’t exercise it, it won’t stay strong. That’s why it’s important to keep our mind active, to keep on learning throughout our life. We can do this by reading, playing memory games and seeking out new experiences. More likely, the lives you all live are so busy and stimulating that this in itself may sometimes interfere with learning. First, the information needs to be recorded, in other words, learned. And for busy people like you and me, that will be where the real problem often lies. If we are distracted, or we are trying to think what we are going to do next, the incoming message just might not be getting recorded effectively. And that leads to the first tip for students who want to improve their memories.[27]Give your full attention to the information you hope to retain. Research clearly shows the advantages of this, and also of active learning, of consciously trying to visualize a new fact, perhaps to make a mental picture, even a wildly ridiculous one, so the new fact will stick in memory.[28]Let me illustrate that for you here a little more concretely.
