Pseudo-forgetting is a combination of two words – false and failing to recall. Actually, it is an instance where you are unable to remember something simply because you did not learn it in the first place!
Pseudo-forgetting is also referred to as mental blur in which there is no complete learning as information was never fully stored in the brain. (1)
There is no true learning since perceived information was never rehearsed nor transferred to long-term memory. It was only held briefly as short-term memory. (2)
