MEMORY OUTLINE What is Memory? Traditional 3 stage model of memory Encoding, storage and Retrieval Model Biological Approach What is Memory? “Memory is an internal mental process, which records or represents some prior events or experience.” We learn information, skills, obtain experiences. If these skills are not recorded mentally, we will end up relearning the same things over and over again. It is the memory process which helps to retain the information we gather from the outside world. It is the memory process through which the information obtained, are retained in organized manner. This organized retention also helps you to learn and organize upcoming information for future use. This mental process is internal. The memory process, how does it occur, has been explained through various theories or models. The most popular approaches to explain memory are as following. 1. Traditional 3 stage model of memory 2. Encoding, storage and retrieval model 3. Biological model TRADITIONAL 3 STAGE MEMORY MODEL OR 3 BOX MODEL 1

According to this model, there are 3 stages of memory required to complete the memory process. Each stage has different purpose, different capacity and different duration to accomplish memory process. Those stages are: 1. Sensory Memory 2. Short Term Memory 3. Long Term Memory. 1. Sensory Memory: This is the very first step of memory process. Before we retain any learning skill or information, we obtain or access the information through various sensory modalities. For example, we obtain visual information through our eye. We obtain auditory information through ears. We obtain olfactory experience through nose. The purpose: The purpose of this stage of sensory memory is to obtain the information and retain the exact duplicate image of the experience long enough to focus on the relevant part of the information and transfer to the Short Term Memory Box. The duration: The information obtained, lasts only for a brief period of time in this stage. The brief duration varies in different sensory modality. For example, visual experience is Iconic memory image which lasts only ½ seconds. Auditory memory is Echoic memory, which lasts 2-4 seconds, before the information is either dropped out or transferred to next stage of memory. The Capacity: Researches have indicated that sensory memory has unlimited capacity. This stage can absorb unlimited number of information. Because, initially we are influenced constantly by 2

unlimited number of stimuli. 2. Short term memory: The information obtained through various sensory modalities is transferred to this second stage of memory. The information transferred to this stage is held in this box temporarily until those are transferred to Long term Memory. Purpose:
