IQ and working memory

Posted on July 14, 2007

Working memory capacity is closely related to general intelligence. This has been observed in several different studies that evaluate the correlation between measures of intelligence and working memory.

A study published last week affirmed this finding, and also furthered our understanding of the factors underlying working memory capacity. Awh, Barton, and Vogel’s research showed that working memory capacity (on average, about 4 items) is not affected by the complexity of the items remembered. More complex stimuli will be remembered with less detail, but the amount of information remembered is about the same.

    Does IQ correlate to short term memory, such as remembering an increasing number of digits in the same time span view of each
    set?

    The ability you’re describing is a mix of short-term memory and processing speed. Each of these abilities is correlated with IQ, so I would guess that the combination is as well.

    I don’t like people who prefer to guess
