| | Iconic memory - Wikipedia, the free encyclopedia |
 | | Although four-to-five alphanumeric characters can commonly be reported after a single brief exposure (e.g., James McKeen Cattell, 1886), observers have frequently reported the phenomenal impression of many more elements immediately after display presentation (e.g., Gill and Dallenbach, 1926). |
 | | These two observations can be reconciled if it is assumed that visual memory [1] consists of two parts: one, a rich, but rapidly decaying sensory trace of the entire stimulus display; and two, a short-term memory store of lower capacity, able to retain its contents over several seconds. |
 | | This finding is consistent with previous studies of a similar kind (e.g., Cattell, 1886), and suggests that whole report is limited by a memory system with a capacity of four-to-five items. |
