Cognitive association

While driving back from the office, i tuned into an fm station which was playing a Kishore Kumar song of 70s, a song i used to know but had not heard for the last god knows how many years. As the song was playing, i started singing and to my astonishment, i was able recollect every word and sing alongwith. I started thinking, how is it that i can remember a song so old and never heard for so long but it takes a lot of work to remember Pythagorus theorem. I remember my teacher telling me once, rhythmic patterns are easy for our brain to remember.

What it is that our brain can remember quite a lot things and can store it for so long? I read an article a while back which states, our brain stores data in cells as layers and its tagged in a certain way so that it can be retrieved with a certain stimulus, which in the case of this song will be the tune. I feel its fascinating and easy to compare how data is stored in computers. I am sure even programmers would have used this analogy.

To take it further, if it is true that our brain is a kind of hardware or a data storage then our ability to create associations will be RAM in computer parlance. Can we determine the size of our storage? we start terming people as 500 GB or 1 TB storage... then what about RAM? similarly we start using terms like person with 1GB RAM. So, our bio will read as - engineer, MBA with 500 GB storage and 1.5 GHZ RAM. The unfortunate part is, our hardware can not be upgraded :-(

Coming to cognitive associations, a lot that we make a meaning of is driven by cognitive associations. I feel, our ability to understand and appreciate is limited by expansion of the universe as understood by us. For example, if my brain is not exposed to classical music at all, its very difficult for me to appreciate how good or bad a piece of music is. For us to be able to absorb all that is good and bad, the starting point is about being open to it.

Typically, post the age of 40, you get affected by presbyopia - inability to decipher when objects are kept close to eyes. My feeling is, its as much to do with cornea as with your brain. There is something that is happening in your brain that is not deciphering the signal sent by your eyes, sure, the signal itself is weak but the brain is not able amplify that signal to make meaning out of it. Its here that the RAM comes into effect. Infact, if you do an experiment, keep things that are known at a short distance and see how you can identify them and then keep something that is totally unknown, see how you struggle. This is a clear case of cognitive associations.

We are driven so much by cognitive associations, our comforts draw a lot from cognitive association, so more your experience and create an association, easier for you to get comfortable. Is there a catch there, not sure, its to do with the stages of life, if you have experienced a lot in formative years, easier for you to deal with the world around you in the later part of the life.
