How the human memory functions is a very intricate and misunderstood subject. As this subject affects each and every one of us in our daily living, there have been numerous detailed studies undertaken to determine how this complex activity takes place within our brains. In reality, while there has been a great amount of progress in understanding the human brain and human memory it is impossible to reach any absolute consensus among the experts as to the mechanics of human memory. In simple terms the human memory can be likened to a DVD recorder, although it is far more complicated in its workings.
The human memory is able to retain key information that we like to revisit time and time again. It is also extremely complex in that it allows us to recall feelings and sensations that we have experienced. As well as these elaborate functions our memory recalls how to carry out relatively simple daily functions such as eating, walking, talking and the like.
There is so much more for scientists to learn about the human memory and as previously alluded to, the study of the human memory will give rise to many more disagreements than agreements among the leading experts in the study of the human brain and how it functions. Nevertheless, what we do know is the human memory involves three main functions which are short term memory, sensory memory and long term memory. There is also one more type which is known as the working memory.
In sensory memory the human memory recalls something that happens in a split second and occurs after the mind forms its first perception. It is like being able to look at at an object and then immediately commit the details to memory. Sometimes some of these details or information actually moves into short term memory. This is the part of a human’s memory that enables us to recall a happening or object a few seconds or even a minutes after it has first occurred.
The newly discovered human memory function that is referred to as working memory is very much like short term memory because it is a function where there is not very large storage needed to perform tasks inside the mind. The difference between working memory and short term memory is that the former is more to do with purpose while the latter is dependent on duration of time.
The other human memory function that interests many people is the long term memory, that unlike short term memory does not disappear after a few moments. Information committed to the human long term memory can possibly remain in the brain for many years. There is no definitive agreement among psychologists about the duration of long term memory, some argue that it is a memory that lasts forever, while others feel it only lasts for a few years at the most.
The study of the human brain and human memory functions continues and our understanding of its mechanics grows day by day. Even with the amazing technological advancements we see on a daily basis I doubt if we will ever truly get to know everything about the human brain and how it works – well at least not in our lifetimes.
Ancient Snowy Mornings, Bristlecone Forest Ca
Image by ™ Pacheco
It snowed most of the night. I couldn’t really sleep. But around 1:00 AM or so, as our web weatherman predicted… clear skies would in fact prevail. I have to say, I was starting to think they had the whole thing wrong. Stars glimmered thru my little FJ window, as the bitter cold swiftly crept into my little traveling hotel in the mountain tops of Inyo. I had woke to start the engine and heat the cabin a few times during the long night, but It was now time to venture out under the disappearing stars and into the dawn. The fresh snow that fell the last few days would soon melt away in the predicted sunny blue monday skies, so I had maybe 2 or 3 hours before my eastern sierra back drop dripped away. I did have to search out a near "thing" thru the softly powdered ancient hills, careful not to walk in places that might be used inside a future foreground. It does pain me to disrupt the beauty of freshly fallen snow for any reason. It’s as though no human on earth could ever lay it down in more a perfect and random way. Just as it should and foreve will be, without apology… without conscience. It didn’t take long to find a subject, as these hills are literally scattered with subject matter. A wide angle put me to close to this fella, and with my small 5′ 7" perspective it’s limbs obscured my softly packed sierra backdrop. Sometimes I choose to break a solid line through an image with the subject, however I really didn’t like the effect here. I chose to stay back with a telephoto… back back way back… just until the snow capped peaks shinned a little in the sharp morning light now painting the hills to light and dark contrasts of golden wow. It all happens so quickly doesn’t it. Replaying it in my brain now feels like one giant stream of thought happening over eons of time, yet the entire process was about 10 minuets long. Once I had this shot, I played with some various comps, close and far, broken and not broken, wide and long… until the big blue sky finally invaded my tranquil snowy hill. Trust your instinct but plan to be surprised I always say. Happy mistakes happen at the most unplanned moments and there is no rhyme, reason or rule book to accommodate or calculate for those moments. I traversed the snow covered hilltops well till noon gathering every star flare thru ancient limbs that I could, I even watched some afternoon football on my ANCIENT ipad. Soon after the game, I planned to venture to the hilltops above the ancient groves. somewhere off the beaten path with a far away view. Twilight approached and I suspected a giant earth shadow would soon creep over these ancient hills. I could hardly wait. I find it’s always best to be the first in line. Random happenings seem more vibrant and exciting from the front row.
