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.
Chunking (psychology) In cognitive psychology, chunking is a process by which small individual pieces of a set of information are bound together to create a meaningful whole later on in memory. [ 1] The chunks, by which the information is grouped, are meant to improve short-term retention of the material, thus bypassing the limited capacity of ...
Memory capacity can be increased through a process called chunking. [29] For example, in recalling a ten-digit telephone number, a person could chunk the digits into three groups: first, the area code (such as 123), then a three-digit chunk (456), and, last, a four-digit chunk (7890). This method of remembering telephone numbers is far more ...
Short-term memory. 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 ...
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 adaptive control of thought (ACT) [37] (and later ACT-R (Adaptive Control of Thought-Rational) [38]) theory of cognition represents declarative memory (of which semantic memory is a part) as "chunks", which consist of a label, a set of defined relationships to other chunks (e.g., "this is a _", or "this has a _"), and any number of chunk ...
Memory span. In psychology and neuroscience, memory span is the longest list of items that a person can repeat back in correct order immediately after presentation on 50% of all trials. Items may include words, numbers, or letters. The task is known as digit span when numbers are used. Memory span is a common measure of working memory and short ...
Storage (memory) In mental memory, storage is one of three fundamental stages along with encoding and retrieval. Memory is the process of storing and recalling information that was previously acquired. Storing refers to the process of placing newly acquired information into memory, which is modified in the brain for easier storage.
