Baddeley and Hitch (1974) proposed an alternate working memory model for the multi memory storage model as a way to represent short-term memory further subdivided. It shows that the working memory consists of three parts. These are central executive, voice loop, and visual space panel. The central executor is an integral part of working memory. This is morphological (that is, it is not visual or audible). This is the most important component of the model and is responsible for monitoring and adjusting operations from the system.
There are multiple stages in the formation of persistent memory, and information may be lost (or forgotten) in the process. The multi-memory model suggests that long-term memory is performed in three stages. The incoming information is passed through short-term memory through sensory memory and then passed to long-term memory instead of once. Information encoded at each step has its own period. First, you need to pay attention to the information you want to encode - this is sensory memory. Since our attention has been switched, incoming messages are normally fleeting like snapshots, but that includes sound, feel, and image details
Long-term memory is not permanently stored in the hippocampus. These long-term memories are important and it is dangerous to save them only in one brain location - damage to that area can lead to all our memory loss.
Most memory theory will be forgotten. Multilinear models, working memory models, and processing levels tend to evaluate oblivion by missing time, practicing time, or destruction. This includes displacement theory supported by Waugh & Norman (1965), search failure theory, and Cue-dependent forgetting theory, both of which are supported by Brown & McNeill (1966). However, most of the large-scale memory theory tends to ignore such environmental factors. Flash memory (Brown & Kulik 1977) Even if information is rehearsed only once, there may be people who retrieve forgotten information due to environmental events. Although an individual may have forgotten information, it may be forgetting information, but simple environmental factors can cause information.
