Some people believe that cognitive thoughts are tied to memory. However, a new study is suggesting that there is no link between IQ and short-term memory.

Researchers from the University of Oregon suggest that even if some people are more equipped to remember a sequence of numbers or puzzles, they do not necessarily have a higher IQ than those who cannot memorize well.

"The number of things people can remember is robustly correlated with fluid intelligence - the larger number remembered, the higher the IQ." said Edward Awh, a psychology professor and a member of the Oregon Visual Working Memory and Attention Lab. "Resolution in memory is not predictive of IQ at all."

The researchers noted that previous studies have indicated that one's short-term memory capacity was a reliable predictor for the patient's IQ. In order to determine this, the authors used clarity, which they described as "relating to how well a person can detect small changes."

The study examined the importance of clarity when one is trying to remember certain facts and found that it did not play a part into one's overall IQ.
