Fig. 5. Reinstatement of short-term memory representations during long-term memory retrieval.

Fig. 5.

(A) Representational reinstatement of maintenance-related activity patterns during retrieval for remembered items (MRS). The line plots on the right show averaged item specificity values across the maintenance period for individual retrieval time windows. The shaded area shows a retrieval time window with significant reinstatement of item-specific representations for remembered items. (B) MRS for forgotten items. Here, the shaded area shows a time window with a significantly lower WI than BI MRS. (C) Comparison of item-specific MRS for remembered versus forgotten items. A significant cluster between 150- and 840-ms preretrieval response showed greater item-specific MRS for remembered than forgotten items (blue shaded rectangular area). (D) Averaged MRS values within the cluster found in (C). Post hoc comparisons indicate greater WI than BI similarities for remembered items, but an opposite effect for forgotten items. The result also shows greater WI MRS for remembered than forgotten items. Dots indicate MRS values of individual participants. (E) Representational formats of remembered items during retrieval. The colored horizontal bar indicates the time window showing a significant match with the representational format in the DNN/semantic model. (F) Representational formats of forgotten items during retrieval. *P < 0.05; **P < 0.01; ***P < 0.001.
