Divided Attention

Do all of our cognitive processes withdraw from the same cognitive bank? How is it that we are able to drive a car, chew gum, talk on the phone and listen to music all at once? Is it possible that our mental resources are somehow specialized in such a way so that different tasked are allocated different resources at different strengths? Our brain is unfathomable in it's ability distribute responsibility to different regions and the storage of it's memory will and can never be known. With technology many questions are being answered and with regards to divided attention. Brain imaging techniques such as the PET scan uses 2-deoxyglucose, which is injected into the patient's carotid artery. Because of its similarity to glucose (brain fuel) it is absorbed by active energy consuming neurons. Fortunately this form of glucose derivative does not become metabolized hence giving us the researcher the ability to tell where the activity is located with a precision of a few millimeters. The PET scan was at on time the only tool used to find the location of neurological processes but now they have fMRI, which is less time consuming and less messy. With these imaging tools, the use of the computerized tachistoscope and t


he educated inferences by highly educated individuals we are getting closer to understanding the brain and the complex web of processes present in divided attention.

Activation Levels and Response threshold

Working memory has its limitations and divided attention can only be so "divided". Cognitive processes take effort and there is some times a tie up on the neurological super highway because of the time required to put forth that effort. The way our brain deals with these little tie-ups is a response-selector. A response-selector can only deal with on thing at a time, just like a waiter can only take one person's order at a time. If two consecutive tasks require the response-selector one ends up waiting while the selector deals with the other task. Most tasks do not require a constant aid of the response-selector so you may select and then initiate an action and the time you spend carrying out that action frees up the response-selector to take on another task, come up with a solution and then initiate the response for that task. This process is a cycle where response-selector bounces from task to task this is commonly referred to as time-sharing and is evidence that divided attention is also task-general.

I found this topic of state dependent memory very interesting. I did have a vague understanding of state dependent memory; it wasn't till I read the detailed description of it in our book that I really grasped the idea. I was able to interrelate it possibly with a psychological disorder called post-traumatic stress disorder in soldiers and the problems with coming back to civilian life. After reading the text I speculated that state dependent memory of wartime events could be triggered if a stimulus was to be generalized in some fashion to a stimulus present in a war environment. My best friend's dad was in Vietnam and suffers from post traumatic stress disorder I have spent countless nights drinking with him listening to his stories and firing questions. He has told me his war time memories in such detail I am going to use them in some shape or fashion to write a book. He has told be that when he gets really stressed out he loses awareness and is in battle again. I believe that the stress is the connected state dependent memory. He is able to relive the horrible torment of war only in the presents of extreme stress since those memories were entered into his long -term memory during that emotional state.

Further evidence of state dependent memory is how I seem to recall information so much better and quicker when I have a cup of coffee. This is because there is not a night that goes buy that I don't have a cup of coffee when I'm studying. The coffee must effect me on a multitude of levels including olfactory and taste not to mention the arousal of mood experienced by the caffeine.
