The theory proposed a model containing three components: the central executive, the phonological loop, and the visuospatial sketchpad with the central executive functioning as a control center of sorts, directing info between the phonological and visuospatial components.The central executive is responsible inter alia for directing attention to relevant information, suppressing irrelevant information and inappropriate actions, and coordinating cognitive processes when more than one task is simultaneously performed.The dynamic nature of memory is probably not a design flaw; it can allow us to update existing knowledge in light of new information.Marciia Firstly although I have had it sometime never really used it.used the term to describe their "short-term store".What we now call working memory was formerly referred to variously as a "short-term store" or short-term memory, primary memory, immediate memory, operant memory, and provisional memory.Moreover, distinguishing intrusion errors on the basis of their permanence in memory, we found that poor comprehenders were more likely to intrude items that were maintained longer in memory than were good comprehenders.

introduced the multicomponent model of working memory.Metabolic activity (green and red colors) in the hippocampus (white dotted line) of animals that underwent extinction training in combination with HDACis (right) is significantly higher than in animals that underwent extinction training alone (left).Metabolic activity serves to estimate the learning capacity of an animal.Memories are automatically reactivated when subjects return to an original learning context, where updating by incorporating new contents can occur.However, when in a novel context, updating of existing memories does not occur, and a new episodic memory is created instead.
