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.
An example of mnemonic devices are PEMDAS or Please Excuse My Dear Aunt Sally; this is a device for arithmetic when solving equations that have parenthesis, exponents, multiplication, division, addition, or subtraction and what order to do each calculation. Words or an acronym can stand for a process that individuals need to recall.
German philosopher named Hermann Ebbinghaus decided to measure his own memory for lists of nonsense syllables at various times after studying them. He decided to draw out a curve of his forgetting pattern over time. He realized that there is a rapid drop-off in retention during the first tests and there is a slower rate of forgetting later on.

Decay Theory is caused by time itself. Decay Theory is a passive method of forgetting as no interference is produced. [35] Interference Theory is an active process because the act of learning new information directly impedes the recollection of previously stored information.
Another explanation for why we forget learned information is the decay of information. 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]
Figure A: Normal Decay Figure B: Sleeper Effect. The sleeper effect is a psychological phenomenon that relates to persuasion. It is a delayed increase in the effect of a message that is accompanied by a discounting cue, typically being some negative connotation or lack of credibility in the message, while a positive message may evoke an immediate positive response which decays over time.
Human communication can be defined as any Shared Symbolic Interaction. [6]Shared, because each communication process also requires a system of signification (the Code) as its necessary condition, and if the encoding is not known to all those who are involved in the communication process, there is no understanding and therefore fails the same notification.
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.
