Sensory Memory

 

Hello everyone and welcome back!

      Today I will be writing on the three types of memory and I will be starting from the sensory memory.

 Sensory Memory

The sensory memory is otherwise known as the human working memory, the memory in action. This part of the human memory is always active. The sensory Memory is connected to the human senses and responsible for the perception of information. The sensory Memory is a detailed yet brief memory that allows individuals retain impressions in their original forms, aside that the sensory Memory retains information in it's original form, it also retains tremendous amount of information. In every moment of one's life, the human senses are actively involved in perceptions, feelings, smelling and hearings through the various sense organs, whilst this informations are important there is still no possible way to remember each of it and how it was experienced. So what the sensory Memory does is to take the information in details, loose it in a matter of second but takes a snapshot (important details) and allow you to pay attention to it until it gets transferred into the next stage of memory which is the short term memory. Impulses received through sensory memory lasts for just 3 seconds or even less. Sensory Memory has different types because of it's uniqueness in receiving informations from different sources. The 3 types are;

Iconic memory: Also known as visual sensory memory, iconic memory involves a very brief image. This type of sensory memory typically lasts for about one-quarter to one-half of a second.

Echoic memory: Also known as auditory sensory memory, echoic memeory involves a very brief memory of sound a bit like an echo. This type of sensory memory can last for up to three to four seconds.

Haptic memory: Also known as tactile memory, haptic involves the very brief memory of a touch. This type of sensory memory lasts for approximately two seconds.
