Decay theory

Decay theory proposes that with the passage of time, memory fades. Information cannot be fully retrieved after a long span of time. When we start learning some new concepts, neurochemical memory traces are being created. Over the period, these traces automatically disintegrate. Short term memory system is affected by the decay theory where old memories are more likely to attack the system of the brain.
