Concpet of memory
1. Sensory memory is the memory where you recieve info from your senses, this travels to the brain. It is retained for a shot amount of time since this is not of great importance.
2.When you feel a surface and it transfers the info about its texture, this is rapidly forgotten.
3.visual about 1 second, and auditory about 4 seconds.
4.This is the stage after sensory memory, in here slective attion will pick which of the memories are important and move them from sensory memory to short-term memory. They are in the form of images or sounds, this gives room for short computations. After that they are moved to other parts of the memory system or discarded.
5.George Miller in 1956, and it is +/- 2 making it from the range of 5-9.
6. Chunking refers to the configuration of large amounts of information, into small ones, which a fit to structure and acomodation of memory.
7.Number:3-4 Letters:3
8.Acoustic
9.This type of memory can last from days to decades. Memories become long term with the proccess of rehearsal and meaningful association, this means that you see it quite often and you give it importance, therefore your brain remembers it for a longer period of time.
10.This model states that there are 3 ways of memory stores, sensory memory, short term memory and finally long term memory. It categorizes them by the duration they last, sensory being to the maximum of 4 seconds, short term memory being about 18-20 minutes, and it stores things by chunks, and finally long term memory which lasts up to a lifetime.
11.1. Not all of the rehearsal leads to the improvement of retention2. STM is in terms of the number of units that can be processed an any one time, he gave 7 +/- 2, but recent researchers have developed 5 +/- 23. The sensory stores are sensory systems, not memory systems as most people think of the term "memory."
12.This model concretes in Long Term Meory and the processing that occurs there, it gives an alternative to the multi store model that suggests info is transfered by rehearsal. This model suggests that the depth or level at which we process information determines its place in LTM and also how well we recall that information, meaning the more we think about it, the longer it stays in our head.
13.Continiously repeating the material to be remembered. Repeating vocabulary words to learn them.
14.This time of rehearsal involves comparing something new with something you already know that is stored in your Long term memory.Relating someone new you meet named John and associating it with someone you already know called John.
15.Craik and Lockhart developed in the year of 1972 the levels of processing models and the concepts of maintenance and elaborative rehearsal.

The Halo effect-Solomon Asch

Alzheimer's disease is problably one of the worst ways to grow old. On the documentry that we saw in class it showed us different people, on different stages of the disease, some way more advanced than others. When a person reaches 65 years old, their chances of developing their disease increase greatly, and every 5 years after that chance grows exponentially. What alzheimer affects is in essence the long term memory of the diseased. As the stages progress the subject becomes much more alien to their memories, and motor skills. Normal everyday tasks that they would preform when they were young become almost impossible for them to execute. Things like driving, of even sorting groceries, this is since they forget key things like traffic signs. Also the jugdemente of the subject is also affected, they sort of go back to a childhood stage in which they are not resonable or trustworthy.I feel threatened by it, since it supposly runs in my family, although studies say other than that

After seeing this video having to do with memory, i think I view at things quite differntly. Since before this I did not know how crucial memory was to our every day living, sure i knew it was of some importance. But i could not see how it revolved around every single task, and action we take in life. After the video, there was not like some specific thing that I leraned, i think i just became more aware of concious of how memory is fragile. I think twice know before doing somethingh that could corrupt it or damage it. And also I became a bit mor afraid since my family has a genetical hisotry of al zaihmer. Which is a very sad disease that take out all of one's character before ending one's life. As of today when I see someone doing drugs, or drinking excessivly, I can not help it but to think of the damage that it will eventually cause in their memories, and expierences

The Stroop effect is a demonstration of the reaction time of a task, when the name of a color ( "red," "pink,") is printed in a color not denoted by the name (the word "green" printed in blue ink instead of green ink), naming the color of the word takes longer and is more prone to erors than when the color of the ink matches the name of the color. The effect is named after John R. Stroop who first published the effect in English in 1935. The effect had previously been published in 1929, but only in Germany. The original paper has been one of the most cited papers in the history of experimental psychology, leading to more than 700 replications. The effect has been used to create a psychological test that is widely used in clinical practice and investigation.The experiment required the participants to read the written color names of the words independently of the color of the ink . Second experiment, stimulus 2 and 3 were used, and participants were required to say the color of the letters independently of the written word with the second kind of stimulus and also name the color of the dot squares. If the word "yellow" was written in red, they would have to say "red," but not "yellow"; when the squares were shown, the participant would have to say its color. In the third experiment, tested his participants at different stages of the tasks and stimulus used in the first and second experiments, to account for the effects of association.

1. Becuase in many of the studies preform by researchers, the resullts indicate that a person becomes much less eficent on the activities the make, than if they did them them 1 by 1. Therefore, what we think is multitasking is no more than a myth.

2Studies showed that when the human brain is presented with multiple tasks, it puts them in order of importance. This in time makes the brain take longer to preform the tasks.

3. This realese of strees hormones, and adrenaline make the brain work worst than in normality. The adrenaline makes us loose focus, while the stress clogues our brain from preforming at it's best.

5. The author concludes that multi-tasking is actually a myth. ANd that in instead of increasing our efficency, t decreases it greatly since our focus is gone bad.

Bambuti are pygmy hunter gatherers, one of the oldest indigenous people of the Congo region of Africa. They are made of bands which are relatively small in size, ranging from 15 to 60. Population is about 30,000 to 40,000 people. Four distinct cultures, within the Bambuti. These are the Efe, which speak the language of their Bantu tribe (the Balese or Mamvu), the Sua, who speak the language of their neighboring Budu, the Mbuti, who speak the language of the neighboring Bila, and a small subgroup of the aka who speak the language of the neighboring Mangbetu tribe. Colin Turnbull was recgonized with his book The forest people, an admiring study of the bambuti. In 1972, he did a sequel, the highly controversial Mountain People, which was about Ungada hunger-plagued Ik.
