Fading away of a memory over time
A
Interference
B
Decay
C
Amnesia
D
Storage
Explanation: 

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: -Trace decay theory states that forgetting occurs as a result of the automatic decay or fading of the memory trace. 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.

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: -This work suggested that memories might fade more rapidly as we age because memory is encoded by fewer neurons, and if any of these neurons fail, the memory is lost.

Detailed explanation-5: -The Petersons concluded that short-term memory has a limited duration and that when rehearsal is prevented information will decay after about 18 to 30 seconds.
