The second step is storage whereby the human mind places information in the memory for storage. The final part is the ability of a human being to recall and recover the stored information in times of need that is when a person needs to utilize the memory.

Different subjects were asked to repeat the different letters present in different rows. The subjects recalled what they saw but they could not remember it for a long time.

This information is also short lived but the time duration of this memory is greater than that of the sensory memory. This time is around 30 seconds and this memory is used basically in short tasks.
