Memory process includes encoding, consolidation and expression phases. Also, at least two types of memory exist according to duration: short-term memory (STM) and long-term memory (LTM). STM and LTM usually differ by the absence or presence of a consolidation phase. Recognition memory refers to the ability to identify an object or a situation and judge if it was previously experienced or not. But sometimes, memories are susceptible to competition often leading to amnesia. One of the possible mechanisms to account for amnesia by competition is the retroactive interference (RI). RI is characterized by the disruptive effect of a new learning experience on a previously encoded material. Is recognition memory susceptible to RI? What are the phases, types and brain region involved?
