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.
4.
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.
