The psychologists recognize four types of memory: reintegration, reproduction, recognition, and relearning.
A) THE REINTEGRATION:
The reintegration supposed the reconstruction of events or facts on the basis of partial stimulus, which serve as reminders.

B)  THE REPRODUCTION:
The reproduction is the active recovery and without help of any element of the past experience (for example, a memorized poem).

C)  THE RECOGNITION:
The recognition is referred to the capacity of identify stimulus previously known.

D)  THE RELEARNING:
The relearning shows the effects of the memory: the known subject is easiest of memorizing one second time.

Generally, the memories are less clear and detailed than perceptions, but sometimes a memorized image is complete in each detail. This phenomenon, known as eidetic memory, or eidetic images, is done frequently in children, who sometimes are able to reconstruct an image so complete that they can reach to spell an entire page written in an unknown language that hardly they have seen during some moments.
