Working memory capacity

Cards in this group · 8

1. A6.02.1The number of items working memory can hold at once is limited
2. A6.02.2Retention is brief and vulnerable to interference
3. A6.02.3Requiring users to remember content across pages is itself a design flaw
4. A6.02.4The classic capacity estimate is closer to four chunks than the earlier figure of seven
5. A6.02.5Without rehearsal, working memory content decays naturally within roughly ten to twenty seconds
6. A6.02.6Rehearsal extends retention, but draws on the same limited processing resource
7. A6.02.7Capacity varies with item complexity, so simple and complex items can't be compared on one number
8. A6.02.8Capacity limits and time-based decay are two independent mechanisms, and easing one doesn't substitute for the other
