As an expert in the field of cognitive psychology, I'd like to delve into the intricate workings of human memory, a fascinating subject that has been extensively studied and continues to be a topic of great interest. Memory is a cognitive process that involves the encoding, storage, and retrieval of information. It is a crucial aspect of our daily lives, enabling us to learn from past experiences, recognize familiar faces, and perform a myriad of tasks that require recalling previously acquired knowledge.
There are several ways to categorize memory, but one of the most common distinctions is between three types: sensory memory, short-term memory, and long-term memory. These types are part of a larger model known as Atkinson and Shiffrin's multistore model of memory, which was proposed in 1968.
Sensory Memory
Sensory memory, also known as sensory register, is the initial stage of memory processing. It is extremely brief, lasting only a fraction of a second. This type of memory holds the immediate perceptions from our senses—sights, sounds, smells, tastes, and tactile sensations. The capacity of sensory memory is vast, but the information it holds is quickly lost unless it is attended to and passed on to the next stage.
Short-Term Memory (STM)
Short-term memory, sometimes referred to as primary memory, is the second stage. It is where information is held temporarily for a short period, typically a few seconds to a minute. The capacity of STM is limited; Miller's famous paper from 1956 suggested that the magical number seven, plus or minus two, describes the approximate number of items that can be held in STM. This is often referred to as the "magical number seven" or the "chunking" principle. Short-term memory is also where we manipulate information through processes like rehearsal and organization to maintain it in our conscious awareness.
Long-Term Memory (LTM)
Long-term memory is the final and most enduring stage of memory. It has a much larger capacity and can hold information ranging from minutes to a lifetime. LTM is where information is consolidated and can be retrieved later. It is organized and can be accessed through various cues. The consolidation process in LTM is believed to involve the strengthening of neural connections through repeated rehearsal or through significant emotional experiences that make the memory more robust.
In addition to these three types, there are other distinctions made within the realm of memory, such as explicit (declarative) memory and implicit (non-declarative) memory. Explicit memory involves the conscious recollection of facts and events, which can be further divided into episodic memory (personal experiences) and semantic memory (general knowledge). Implicit memory, on the other hand, is the unconscious retention of learned information, which influences future actions or behaviors without the need for conscious recall. This includes skills and habits, such as riding a bicycle or playing a musical instrument.
Understanding the intricacies of memory is not just about academic interest; it has profound implications for our understanding of learning, development, and the treatment of memory-related disorders. As research continues, our insights into how memory works and how it can be improved or restored in cases of impairment will only deepen.

In this section we will consider the two types of memory, explicit memory and implicit memory, and then the three major memory stages: sensory, short-term, and long-term (Atkinson & Shiffrin, 1968).
