Explanation:
How Does Sensory Memory Work?
During every moment of your existence, your senses are constantly taking in an enormous amount of information about what you see, feel, smell, hear, and taste. While this information is important, there is simply no way to remember each and every detail about what you experience at every moment. Instead, your sensory memory creates something of a quick "snapshot" of the world around you, allowing you to briefly focus your attention on relevant details.
Types of Sensory Memory
Experts also believe that different senses have different types of sensory memory. The different types of sensory memory have also been shown to have slightly different durations.
Iconic memory, also known as visual sensory 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, 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, involves the very brief memory of a touch. This type of sensory memory lasts for approximately two seconds.
