Clear short-term memory shows no link with the IQ | Health & Fitness ...

The number of things that people can remember is the strong correlation with fluid intelligence. ? The biggest draw, the higher the IQ, said Edward AWH, a psychology professor and member of the Laboratory of visual working memory Oregon and attention. Resolution of the memory is not predictive of IQ at all.Fukuda put 79 students through a series of experiments in which four or eight objects were projected onto a screen for a moment. After a one second blank screen, an item was returned and the subject was asked whether this object was in the first place.

A person remembers correctly four of the eight elements have just seen, but is vague on the details. Another person remembers only two points, but with an astonishing precision clarity. While capacity translates into a higher IQ?

The discovery that the clarity is not a factor in a person?s IQ does not suggest that the resolution of the memory is not important, the researchers noted. The importance of clarity and resolution, the memory of things is essential, for example, a radiologist examines the images of the internal organs of a patient with potential disease conditions.

By examining the ability to detect changes in small and large objects stored, Fukuda was able to obtain an estimate of the number of two shares held in memory, and the resolution or clarity of those memories. These aspects of memory were then combined with the scores of subjects on tests of fluid intelligence.

Some of the results: 41 percent of Americans polled say they are at least a little ?overweight. But according to their size and the weight, 51 percent are actually overweight.

The idea that the number of elements is very important for short-term memory has been shown in previous studies with the OU. These studies have found that people generally have a capacity to temporarily store items 3-5 of the short-term memory. Previous research has shown that the ability to short-term memory is a reliable predictor of an individual?s IQ.

But the new study, published in the October issue of the journal Psychonomic Bulletin & Review, has tried to give a broader view on the issue to determine which aspects of memory capacity explains the link with fluid intelligence.
