Forgetting or disremembering is the apparent loss or modification of information already encoded and stored in an individual's short or long-term memory.It is a spontaneous or gradual process in which old memories are unable to be recalled from memory storage.
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. However, over time this trace slowly ...
Motivated forgetting is a theorized psychological behavior in which people may forget unwanted memories, either consciously or unconsciously. [1] It is an example of a defence mechanism, since these are unconscious or conscious coping techniques used to reduce anxiety arising from unacceptable or potentially harmful impulses thus it can be a defence mechanism in some ways. [2]
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 ]
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 .
This concept determines the impermanence of memory storage as an explanation for forgetting. [1] Decay theory posits that the process of forgetting is due to the inevitable fading of memory traces over time. [4] For this theory, the length of time that the information has been retained within memory stores is important.
A typical representation of the forgetting curve. The learning curve described by Ebbinghaus refers to how fast one learns information. The sharpest increase occurs after the first try and then gradually evens out, meaning that less and less new information is retained after each repetition. Like the forgetting curve, the learning curve is ...
Ironic control theory, also known as "ironic process theory", states that thought suppression "leads to an increased occurrence of the suppressed content in waking states". [36] The irony lies in the fact that although people try not to think about a particular subject, there is a high probability that it will appear in one's dreams regardless.
