Jacobs discovered that participants could recall nine digits, whereas they could only recall seven letters. This could be because there were only eight possible digits to be read out whereas there were twenty-five possible letters. He also found that short term memory increased when the participant was older. Jacobs came to the conclusion that short term memory has a capacity of five to nine digits, and that age has an effect on it. Age could have an effect because as we get older we have to remember more, so out memory is continuously being trained to remember
