Question
What is the meaning of the terms 'encoding', 'storage' and 'retrieval'?
Solution
The meaning of the terms encoding, storage, and retrieval are as follows:
(i) Encoding − It refers to the first stage of memory in which information is recorded and registered for the first time, in order to be used by memory systems. The external stimulus generates neural impulses in sensory organs during encoding which helps to receive the information and process it in different areas of the brain, in order to derive meaning and represent it to be processed further.
(ii) Storage − It is the second stage of memory in which the encoded information is stored and retained over a period of time to be used later.
(iii) Retrieval − It is the third stage and refers to bringing the stored information into awareness in order to be able to perform the cognitive tasks.
