Memory

Without our memory, we are nothing. Memory is a necessary foundation for our cognitive abilities and helps make us who we are. It allows us to bring the past to the present.The process of memory is broken up into three steps by psychologists: encoding, storage, and retrieval. The hippocampus is the section of the brain that deals with these three steps of memory and is crucial for an intact memory. Psychologists divided human memory as follows:

Sensory Memory:
Sensory Memory is the recollection of a stimulus. Sensory memory is divided into further subdivisions: Iconic Memory and Echoic Memory. Iconic Memory deals with sight. This memory helps us remember how something visible appears to us as we look away or shut our eyes. Echoic Memory deals with sound. This memory helps us replay the pitch and volume of a sound that was heard after it has pasted.

Short-Term Memory:
Short-term memory is also known as "Working Memory". This is responsible for holding onto information that does not need to be stored in our brains. Psychologists believe that we can only hold onto seven (plus or minus two) items at one given time. This helps us recall a phone number that was spoken to us to be written down right after.

Long-Term Memory:
As the name implies, long-term memory is memory that is stored inside our brain for later retrieval. There are numerous branches of long-term memory, explicit and implicit are the major branches.

Explicit Memory:
Explicit memories are memories that we are able to "think" of. The two branches of explicit memory are episodic memory and semantic memory: Episodic memory deals with memories that are life experiences. For example, remembering farting out loud in a library is a memorable life experience that can be recalled. Semantic memory deals with ideas, foods, and concepts. For example, remembering the concept of embarrassment is different from remembering a time you were embarrassed.

Implicit Memory:
Implicit memory is a memory that is associated with skills, habits, and conditioned responses. The major memory underneath implicit memory is procedural memory. Procedural memory does not require any conscious thought, instead, it is our unconscious abilities. For example, hopping onto a bike and riding it requires memory from past experiences. You do not need to relearn how to ride a bike, this is made possible by our procedural memory.
