Q1 :  

What is the meaning of the terms 'encoding', 'storage' and 'retrieval'?


Answer :

The meaning of the terms encoding, storage and retrieval are as follows:

  1. (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 a 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.

Q2 :  

How is information processed through sensory, short-term and long-term memory systems?


Answer :

The information is processed through sensory, short-term and long-term memory systems in the following ways:

  1. (i) Sensory Memory - The incoming information enters through sensory memory which has a large capacity but is of very short duration of less than a second. It registers information from each of the senses with a reasonable accuracy.

    (ii) Short-term Memory - It refers to the system that holds small amount of information for a brief period of time. According to Atkinson and Shiffrin, the information is primarily encoded acoustically and unless it is rehearsed continuously, the information gets lost within 30 seconds.

    (iii) Long-term Memory - The information that survives in short term memory enters the long-term memory system. Once information enters here, it is never forgotten as it gets encoded semantically. Thus, it is a permanent storehouse of all the information.
