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 ]
Toynbee's theory of decay [ edit ] In his acclaimed 12-volume work, A Study of History (1934–1961), the British historian Arnold J. Toynbee explored the rise and fall of 28 civilizations and came to the conclusion that civilizations generally collapsed mainly by internal factors, factors of their own making, but external pressures also played ...
Decay theory states that when something new is learned, a neurochemical, physical "memory trace" is formed in the brain and over time this trace tends to disintegrate, unless it is occasionally used. Decay theory states the reason we eventually forget something or an event is because the memory of it fades with time.
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 that a person is ...
Autobiographical memory (AM) [1] is a memory system consisting of episodes recollected from an individual's life, based on a combination of episodic (personal experiences and specific objects, people and events experienced at particular time and place) [2] and semantic (general knowledge and facts about the world) memory.

The interference theory is a theory regarding human memory. Interference occurs in learning. 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 ]
Memory loss in patients with temporally graded RA strongly follows Ribot's law, meaning that one will experience more memory loss for events closer to the injury or disease onset. [4] This type of RA is commonly triggered in individuals with Korsakoff syndrome due to a combination of long-term alcohol use and Wernicke encephalopathy . [ 7 ]
In 1974, Baddeley and Hitch [5] introduced and made popular the multicomponent model of working memory.This theory proposes a central executive that, among other things, is responsible for directing attention to relevant information, suppressing irrelevant information and inappropriate actions, and for coordinating cognitive processes when more than one task must be done at the same time.
