According to Atkinson and Shiffrin’s theory, memory can be proposed into a model known as multi-store memory model that are composed of sensory memory, short-term memory (STM), and long-term memory (LTM) store. In general, this works via encoding every incoming information, so that it can enter the sensory memory that are limited to our sense of perception. If individuals really give their attention, that information would be transferred and stored in the STM from the sensory memory. Then, the information would be transferred to the LTM store if it has been rehearsed repetitively for periods of time. Generally, the information in LTM store could be recalled via retrieval to be stored back into STM.
