The aim of this research was the effect of off-line time different periods on stabilization and enhancement-based consolidation process in explicit memory. students were randomly divided into 9 groups with distance of 12 h enhancement, immediate interference + retention with distance of 12 h, delay interference with distance of 12 h + immediate retention, delay interference with distance of 12 h + delay retention with distance of 12 h, distance of 48 h enhancement, immediate interference + retention with distance of 48 h, delay interference with distance of 48 h + immediate retention, delay interference with distance of 48 h + delay retention with distance of 48 h. This research consisted of two phases of learning and retention. Alternating serial reaction time and two selection reaction time tasks were used for this research. In retention results showed that group with 48h period occurred consolidation based enhancement. Results showed that in groups with off line period 48 and groups with delay interference with distance of 12 h + delay retention with distance of 12 h occurred stabilization based consolidation. In group with 12h offline period (immediate interference + retention with distance of 12 h) occurred retrograde interference effect. Groups delay interference with distance of 12 h + delay retention with distance of 12 h, and delay interference with distance of 48 h + delay retention with distance of 48 h have better stabilization based consolidation (P<0.05). Finally, results showed that enhancement and stabilization in alternating serial reaction time task cannot be obtained by practice and during session training, but enhancement and stabilization based consolidation obtained after off line stage.
