Weiwei Zhang, a postdoctoral scholar and Steve Luck a professor of psychology, both at the UC Davis Center for Mind and Brain hand out a pair of tests, both of which could separately measure two thingslike the accuracy of a short term memory and the probability that the memory still existed. the test was only was handed to 12 adults.the first test was one of squares to see the squares then see a wheel with the square colors and then see the 3 squares colorless one highlited. "When subjects retained a memory of the color, they clicked very close to it on the wheel — the distance between the click and the actual color indicating the accuracy of the memory. When color had disappeared from memory, however, subjects clicked at random on the wheel". the second test was the same only that instead of colors now shapes and the results are "The finding provides insight into the underlying mechanisms behind memory formation and retention. “The memories are not like flashlights that get progressively weaker as the battery runs low,” Luck said. “They are more like a laptop computer that continues working at the same speed until it suddenly shuts down.” This could be important in everyday life, he explained, because it would provide a mechanism to help us avoid the confusion that might arise if we tried to make decisions on the basis of weak, inaccurate memories." I can use this in the real life with my classmates and make them think.
