Figure 6B(1). Declarative and nondeclarative memories.
There are two memory systems in the brain:— The first system is called declarative or explicit memories. When we
remember and can declare what we have learned or experienced, those are
declarative memories. There are two types of declarative memories:
knowledge (semantic memories derived from philosophical knowledge) and
experience (episodic memories derived from sensory experiences, identified
as events in our lives with particular people, animals, or objects, while we
were doing or witnessing a certain thing at a particular time and place).
Episodic memories tend to imprint longer in the brain and body than
semantic memories.
— The second memory system is called nondeclarative or implicit
memories. When we practice something so many times that it’s become
second nature—we no longer have to think about it; it’s like we almost
can’t declare how we do it—the body and mind are one. This is the seat of
our skills, habits, automatic behaviors, associative memories, unconscious
attitudes, and emotional reactions.
