In the Atkinson and Shiffrin model, what are the three basic types of memory stores?

The three basic types of memory stores in the Atkinson and Shiffrin model are sensory memory, short-term memory, and long-term memory. This model, often referred to as the multi-store model of memory, outlines how information is processed and stored in the human memory system.

Sensory memory acts as an initial stage that captures a brief snapshot of incoming sensory information from the environment. It holds this information for a very short duration, typically less than a second, allowing individuals to experience the stimuli before it is filtered further.

Short-term memory, following sensory memory, retains information for a limited time, usually around 20 to 30 seconds, and has a limited capacity, often described by Miller's law as being able to hold about seven plus or minus two items. This type of memory is crucial for tasks requiring immediate recall or mental manipulation of information.

Long-term memory is the final stage, where information can be stored for extended periods, potentially throughout a person's life. It encompasses a broader range of knowledge, including experiences, facts, and skills, and can be divided into further categories, such as explicit (declarative) and implicit (non-declarative) memory.

Understanding these three components helps clarify the overall structure of memory and how
