p447fig12.45 (left column) LIST PARSE simulations of the proportion of order errors as a function of serial position for 6 item lists with (a) an extended pause of 7 time units between the third and fourth items, and (b) pauses of 5 time units (solid curve) and 10 time units (dashed curve) between all items.  (right column) Simulations (solid curves) and data (dashed curves) illustrating close model fits in various immediate free recall tasks.<BR>||  (Left) Temporal grouping and presentation variability.  Temporal grouping: Inserting an extended pause leads to inter-group bowing;  Significantly different times of integration and activity levels across pause, fewer interchanges.  (Right) Immediate free recall, and [delayed, continuous] distractor-free recall.  Overt rehersal IFR task with super-span (ie 20 item) lists: Extended recency- even more extended with shorter ISIs; Increased probability of recall with diminished time from last rehearsal; Early items in list rehearsed most;.  LIST PARSE (unique) for long lists: Incoming items from recency gradient;  Rehearsal (re-presentation) based upon level of activity.
