Human memory capacity

What is memory?

Memory is a critical component which holds information that we acquire from our learning, past, experience and many more thing which we have done in our life.

Stages of memory:
5. Sensory memory
6. Short-term memory
7. long-term memory

About stages of memory:

1. Sensory Memory: Sensory memory has ability to retain impressions of sensory information after that the whole mind is blocked and only one think is going in your mind. When it works your heart beat increase little bit. But sensory memory is not for long time it is for only fraction of second. For ex- you have seen a guy which is injured from top to end at that you feel something different in your mind this is a sensory memory. Sensory memory has basically two types:

Iconic sensory memory - Iconic memory mainly describe through our eyes movements. Because which things we have seemed in our whole life is stored in our Iconic memory. So eyes play a very important roll in our Iconic memory.

Echoic sensory memory - Echoic memory refers as a mental echo which is happening in our mind. I explain you after workout from your work when you reached the home and you are on bed when you close your eyes there is recall of whole things which you had done in your whole day. This is an echoic memory who repeats things.

Visual memory - Visual memory is same as Iconic memory but difference between iconic and visual memory is iconic memory stored the images in our memory but visual memory after seeing image imagine about that image both memory work together. For ex - you have seen a wonderful car and you want to drive on it then your visual memory start its work and you can drive on the same car.

2. Short- term memory (Primary or Active memory): Short-term memory has a capacity to hold a small amount of information in the active state of your mind, readily available state for a short period of time. The duration of short-termed memory is about 20 seconds. Short-termed memory (STM) is also known as working memory because the information stored in this memory section is in working condition. It store information in your mind temporarily. For ex- sometime it happens with you also that you are trying to recalling something in your mind but you fail. But suddenly you remember that things it is possible due to temporarily stored information about those things in your mind.

8. Long-termed memory (LTM): Long-termed memory is a permanent memory which stored large amount of information for long time and decades. Short-termed memory is the base of Long-termed Memory. Because it is a believe that new information is added in long-termed memory from the short-termed memory. In other words we can say that collection of short-termed memory is long-termed memory. Long-termed memory has basically two types:

Declarative or Explicit memory: Declarative memory stores the facts which you have made in your life like reading book, traveling, any discussed or declared things etc all other knowledge which you have acquired from such thing. Declarative memory is divided into two parts:

• Episodic memory - Episodic memory is a memory of lifetime achievement in your life which you had gain from your past times, events, places, associated emotions and related knowledge.
• Semantic memory - Semantic memory is refers to knowledge about to external world like understanding, meaning, and other related knowledge.

Implicit or Non-declarative memory: The experience gain by us from our past memory or task is known as implicit memory. A type of memory that can be expressed by performing, rather than conscious recall, such as information required during learning, daily habit formation, emotional attachment learning etc. It is also known as Non-declarative memory. Implicit memory is divided into two parts:

• Procedural memory - A form of memory that is used for completing our daily task such as reading, writing, eating etc.
• Classical conditioning - A Process in which firstly person take full attention means neutral stimulus after that person give him a desire answers with the help of Conditioned stimulus. When both neutral stimulus and conditioned stimulus work together it becomes a classical conditioning.
