This method of free associations was developed by an Austrian neurologist, Sigmund Freud to help a patient recall his childhood memories with a view to curing him of neurosis. However, recalling childhood memories is not in the scope of this article. It simply wants to help you improve your memory.
Another way to improve your memory is to close your eyes and visit the house of a friend to which you had paid a visit in the recent past. What do you see with your closed eyes? Are you able to recall the detailed scene of the room in which you had a chat with your friend? Do not tax your brain. Let anything which comes to your notice, be noted by you.
Supposing you recall the chair on which you were sitting, can you recall the table lying in front of you? If you do not put too much pressure on your brain but let the things proceed spontaneously, soon you would be recalling all the details of the room in which you were sitting in your friend's house. Then again close your eyes but this time, try to recall what your friend said to you.
Again do not tax your brain but let whatever comes to your mind be noted by you. If you proceed in this spontaneous fashion, you will be able to recall all the conversation which you had with your friend.
Again visit the same house in your imagination with your eyes closed. Do you recall the smell of the flowers that were lying on the table of your friend in his house? Are you able to recall the aroma of the tea which he served to you?
Again do not put pressure on your brain but let any smell that comes to your mind, be noted. Soon, you will be recalling the various smells in the room. Similarly, you can recall the taste of the tea that you had with your friend, the taste of the cookies that he served you.
So, in this manner, you can improve your memory. You can also do this experiment even with the sense of touch. How a thing felt when you touched it? Was it hard or soft?
