The human body is a complex structure. The brain is the most complicated organ with the most work. Human memory includes the process of storing and storing memory. According to Intelegen Inc., this process has this unique memory process, which contains only three phases. Memory is formed, maintained, and retrieved at various stages of the process. There are three phases in five different types of memory, these three phases are coding, storage, and retrieval. Five memories are categorized by several different characteristics.
Memory has three types: emotion, short term, and long term. These three memory types work in conjunction with the memory process. Sensory memory comes from the senses and lasts only a few seconds. Researchers have indicated that sensory memory is usually limited and showed that you can remember up to 12 items at a time. Sensory memory is focused on only a limited part of the overall environment and is linked to short term memory through a process of excluding other parts. This concentration process is called attention and makes it possible to make information obtained as sensory memory a short term memory.
There are three types of sensory memory. Symbolic memory is a sort of rapidly declining visual information storage device; sensory memory that temporarily stores temporarily perceived images. Echo storage is a rapid attenuation memory of auditory information and is another type of sensory memory that temporarily stores short-term perceived sounds. Tactile memory is a sensory memory that represents a database of tactile stimuli. Short-term memory is also called working memory. Short-term memory expects a few seconds to one minute without rehearsal. Its ability is also very limited. When George A. Miller (1956) worked at Bell Laboratories, he experimented and proved that the memory of short-term memory is 7 ± 2. Number 7 "± 2")
