Main evidence and numbers
| Feature | Auditory digit-span study | Whole-number visual game |
|---|---|---|
| Input | Dem talk digits one after another | Person see digits for screen |
| Grouping chance | E depend on how dem talk am and the strategy | Person fit group am by the way e dey show for screen |
| Wetin score mean | E need the recall and stopping rules for that study | E need the rules wey that game use |
| Direct conversion | Dem never establish am | Dem never establish am |
The auditory study get 763 adults from the community, age 18–65. The traditional forward average na 6.35, but the highest score wey dem reach across the fuller test average 6.77. This difference inside the same study alone show why any published average must include how dem score am. Woods et al., 2010
Why the way dem present am changes the task
Theories about working memory separate how we represent information and how we control am, including verbal and visual-spatial parts. Person fit also change written digits to words for mind, so the difference no simple like calling one pure visual memory and the other pure auditory memory. The way dem present material and wetin person do with am both matter. Baddeley, 2012
To see one whole sequence fit make the way e arrange dey available for grouping. Research on chunking dey study how regular patterns fit compress sequences; the benefit wey come from am concern the structure wey person encode, no be only the raw number of symbols. Person fit handle date or pattern wey e know visually different from digits wey no get connection. Mathy et al., 2012 Miller, 1956
Higher visual score mean say memory strong pass?
Na only for the task and conditions wey dem test. Comparison dey also change how long person see am, chance to repeat am, answer format and stopping rules. Research on span methods stress say these details affect the measure. Better score for one version no automatically mean better score for every working-memory task. Conway et al., 2005
Wetin dey affect am?
Why published memory capacities fit look like dem no agree
Cowan restricted-capacity idea concern chunks under conditions wey dem design to limit rehearsal and contribution from long-term memory. Ordinary digit span fit benefit from those same processes. So if person compare chunk estimate with raw digit count, e dey mix different units and experiment conditions. Cowan, 2001
Intensive practice with memory technique show one clear example: one trained participant learn to remember much longer strings of digits by using organised knowledge, without the same transfer to unrelated material. This na evidence of skill wey person acquire, no be evidence say all short-term storage grow reach the digit count wey display. Ericsson et al., 1980
What about age and sex norms?
Norms must match the way dem present am, timing, language, order of answer and scoring. The adult auditory sample no provide any conversion for visual browser game wey adjust for age or sex. If person apply the average to every online version, useful research reference go turn to ranking wey fit mislead person about themself. Woods et al., 2010 Conway et al., 2005
This same caution pass digit tasks: one meta-analysis show say span and n-back measures get only small overlap, and dem no fit replace one another. So high result for visual number memory no be established n-back score or IQ estimate. Redick et al., 2013
If na to observe yourself, keep each format separate, use the same rules for how long to show am and how to answer, and note whether you repeat or group the sequence. These choices make your own comparisons easier to understand, but dem no create norms wey represent everybody or clinical validation. Woods et al., 2010 Mathy et al., 2012

Test for number memory
Try the visual number memory test and call the result that task score. If you also use auditory span test, write the score down separately. No compare the longest one version succeed with another version average or stopping-rule result.
Common questions
Auditory and visual scores suppose match?
These sources no establish that expectation. The way dem present am, strategy and scoring fit all differ. Woods et al., 2010 Baddeley, 2012
Visual digits still fit use verbal memory?
Yes. People fit change written material to words for mind; the way dem present am no guarantee say na only one memory system dey contribute. Baddeley, 2012
One format better for IQ test?
That one need correct validation. Better score for one particular format no establish say person get higher general intelligence. Conway et al., 2005
