Short-term memory (or " primary " or " active memory ") is the capacity for holding a small amount of information in an active, readily available state for a short interval. For example, short-term memory holds a phone number that has just been recited. The duration of short-term memory (absent rehearsal or active maintenance) is estimated to ...
The term "working memory" was coined by Miller, Galanter, and Pribram, [5][6] and was used in the 1960s in the context of theories that likened the mind to a computer. In 1968, Atkinson and Shiffrin [7] used the term to describe their "short-term store". The term short-term store was the name previously used for working memory.
Later research on short-term memory and working memory revealed that memory span is not a constant even when measured in a number of chunks. The number of chunks a human can recall immediately after presentation depends on the category of chunks used (e.g., span is around seven for digits, around six for letters, and around five for words), and even on features of the chunks within a category.
The storage in sensory memory and short-term memory generally has a strictly limited capacity and duration. This means that information is not retained indefinitely. By contrast, while the total capacity of long-term memory has yet to be established, it can store much larger quantities of information.
Short-term memory is responsible for retaining and processing information very temporarily. It is the information that we are currently aware of thinking about. [2]: 13 Short term memory is also known as the working memory. The storage capacity and duration of short-term memory is very limited; information can be lost easily with distraction. [2]
Research in the 1970s has shown that memory span with digits and words is only weakly related to performance in complex cognitive tasks such as text comprehension, which are assumed to depend on short-term memory. [36] This questioned the interpretation of memory span as a measure of the capacity of a central short-term memory or working memory.
In 1973 Simon and Chase were the first to use the term "chunk" to describe how people might organize information in short-term memory. [10] This chunking of memory components has also been described as schema construction. [citation needed] In the late 1980s John Sweller developed cognitive load theory (CLT) while studying problem solving. [2]
Short-term memory has limited capacity and is often referred to as "working-memory", however these are not the same. Working memory involves a different part of the brain and allows you to manipulate it after initial storage. The information that travels from sensory memory to short-term memory must pass through the Attention gateway. The ...
