Model parameters.

<p>Model parameters.</p

Item activation and reactivation.

<p>A: Activity during storage and recall for different number of stored patterns (1–7 indicated below each display). Blue-red color shows activity (m-values) with dark blue representing 0 and deep red 1. Time is on the vertical axis, item number on the horizontal. The horizontal spacing separates activity during encoding (above spacing) and spontaneous recall (below spacing) in each display. B: m-values during the presentation and recall of a 12 item list. Each item is presented during 2 seconds, in total 24 seconds, followed by a 48 seconds spontaneous recall period. C: The average reactivation time and its standard deviation during presentation (y-axis) as a function of item position (x-axis).</p

Reactivation determines recall probability.

<p>Upper panels: Distribution of reactivation over item input position. Items 1–4 are shown individually, items 5–8 and 9–12 are grouped. Lower panel: Probability of recall of an item as a function of number of reactivations during encoding.</p
