The Atkinson-Shiffrin Memory Model The Atkinson-Shiffrin three-stage model of memory defines three stages of memory-sensory memory, short-term memory, and long-term
memory-through which information passes before it is stored. Information is held in the sensory memory for a split second and then moves into
short-term memory. Then, if the information is rehearsed, it moves into long-term memory. However, most of what enters the sensory memory does
not make it to the short-term memory, as short-term memory has a limited storage capacity.
The short-term memory can hold a limited amount of information for a short duration, typically lasting for a matter of seconds. The duration for
keeping the information can be increased through rehearsal, in which the information is repeated to oneself. The capacity of short-term memory can
be increased through chunking, in which information is organized or grouped into meaningful units or divisions.
Information that is learned is stored in long-term memory. The capacity for long-term memory is vast, and the duration can range from years to a
lifetime, depending on the amount of rehearsal. Long-term memory is divided into explicit memory (the conscious recollection of previous
experiences and information) and implicit memory (the long-term memory of skills and procedures that do not need to be consciously recalled).
