Theory/Cause of forgetting
1)Trace decay theory: [Trace: Sign of memory]
The theory suggests that, the previously learnt information may begins to fade and disappear unless we occasionally retrieve it with the lapse of time. This type of forgetting occurs only in sensory and short term memory.
This theory states memory can be disrupted, interfered with what we have previously learnt and what we will learn in future. It is also classified under two topics:
➡Retro-active interference:It happens when new learning interferes the ability of previously learnt information. Here the previous information may disrupted with the learning of new information. Eg; mathematical calculation.
➡Pro-active interference: It happens when ability of new information endures/interfers the old information. Here we dont want to learn the new things that has been learnt already. Thus, what we previously learnt interfers with what we are currently learning.
3)The repression theory:
Its a theory by psychoanalytic theorist Sigmund Freud. This theory argues much
of our thoughts and ideas which may inaccessible at the moment(pre-conscious) or totally inaccessible at the moment(unconscious).
