Routes to Remembering: the Brains Behind Superior Memory

I'm a little concerned since the control group's average digit span was 12. Though I'm not familiar with the WAIS digit span subtest, I'd make the assumption that this is the combined forward and backwards digit span.

If anyone can confirm my suspicion, it would ease my mind (and ego). Also, after 38.5 years practicing a mnemonic system, I'd expect my digit span to be above 19, combination or not (19 is the highest in the range of digit spans).

Agreed on the second point - a digit span of 19 is implausibly low for the contestants in the world memory championships. For example, the world record for memorising spoken numbers (spoken at 1 digit every 2 seconds) stands at over 400. I can get well over 20 on the digit span tests on this site using mnemonics, and I'm nowhere near the standard of the individuals in the study.

It looks like the method of loci was the most common mnemonic method. "Only the SMs associated the digit stimuli with images (in one case words and then images) of people, animals or objects." This could indicate a visuospatial conversion/deconversion process; I would think a 19-item span for this is impressive.

Related to this, the K. A. Ericsson research that found participants exceeding 60-digits (forward) trained in techniques specifically designed for digits.

The "digit span scaled score," exactly as you said, is forwards + backwards. A 12 digit forward span would be startling!

I feel sorry for these people who have slaved away at memory or chess or calculating to show everybody how smart they are only for some guy in a white coat to come along and blow their cover.
