Effect of immediate, recent and remote explicit motor memory on reconsolidation process and retrograde effect

The aim of this research was effect of immediate، recent and remote explicit motor memory on reconsolidation process based stabilization and enhancement and retrograde interference. The statistical sample were 72 right-handed young girl. subjects were divided into two groups of immediate explicit motor memory (immediate recall، immediate recall + immediate interference)، two groups of recent explicit motor memory (recall after 5h، recall after 5h + Interference delayed after 5h) and two groups of remote explicit motor memory (recall after 24h، recall after 24h + Interference delayed after 24h). This research was consisted of two phases of acquisition and retention and alternating serial reaction time and two selection reaction time tasks were used. In the first phase check out reconsolidation based enhancement and in the second phase check out reconsolidation based stabilization and retrograde interference. In the first phase، results showed that for recall groups after 24h and 5h occurred reconsolidation based enhancement. In the second phase، results showed that for recent (recall after 5h، recall after 5h + Interference delayed after 5h) and remote (recall after 24h، recall after 24h + Interference delayed after 24h) memory groups occurred reconsolidation based stabilization. In group with immediate offline period (immediate recall+ immediate interference) occurred retrograde interference effect.
