The Decay theory is a theory that proposes that memory fades due to the mere passage of time. Information is therefore less available for later retrieval as time passes and memory, as well as memory strength, wears away. [1] When an individual learns something new, a neurochemical "memory trace" is created.
Trace decay theory explains memories that are stored in both short-term and long-term memory system, and assumes that the memories leave a trace in the brain. [16] According to this theory, short-term memory (STM) can only retain information for a limited amount of time, around 15 to 30 seconds unless it is rehearsed.
Long-term memory is the site for which information such as facts, physical skills and abilities, procedures and semantic material are stored. Long-term memory is important for the retention of learned information, allowing for a genuine understanding and meaning of ideas and concepts. [6] In comparison to short-term memory, the storage capacity ...
Forgetting curve. The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it. [1] A related concept is the strength of memory that refers to the durability that memory traces in the brain. The stronger the memory, the longer period of time ...
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.
The interference theory is a theory regarding human memory. Interference occurs in learning. The notion is that memories encoded in long-term memory (LTM) are forgotten and cannot be retrieved into short-term memory (STM) because either memory could interfere with the other. [1] There is an immense number of encoded memories within the storage ...
Baddeley's model of the phonological loop. The phonological loop (or articulatory loop) as a whole deals with sound or phonological information.It consists of two parts: a short-term phonological store with auditory memory traces that are subject to rapid decay and an articulatory rehearsal component (sometimes called the articulatory loop) that can revive the memory traces.
Reconstructive memory. Reconstructive memory is a theory of memory recall, in which the act of remembering is influenced by various other cognitive processes including perception, imagination, motivation, semantic memory and beliefs, amongst others. People view their memories as being a coherent and truthful account of episodic memory and ...
