Detailed explanation-1: -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. When an individual learns something new, a neurochemical “memory trace” is created.

Detailed explanation-2: -Neuroscientists call this phenomenon “memory extinction”: Conditioned responses fade away as older memories are replaced with new experiences. A new study from MIT reveals a gene that is critical to the process of memory extinction.

Detailed explanation-3: -Rehearsal, or mentally going over a memory, can slow this process. But disuse of a trace will lead to memory decay, which will ultimately cause retrieval failure. This process begins almost immediately if the information is not used: for example, sometimes we forget a person’s name even though we have just met them.

Detailed explanation-4: -Trace decay theory focuses on time and the limited duration of short term memory. This theory suggests short term memory can only hold information for between 15 and 30 seconds unless it is rehearsed. After this time the information / trace decays and fades away.

Detailed explanation-5: -Memory decay happens when time passes during which memories have not been accessed. The brain really does have a “use it or lose it” tendency, and when memories and things learned are not reinforced and recalled, those neural pathways tend to lose strength over time.
