The different kinds of memories

We hold on to different kinds of memories.

• Short-term memories last seconds to hours and long-term memories last for years.
• We also have a working memory, which allows us to keep something in mind for a limited time by repeating it.
• Declarative memories are memories you experience consciously, like facts or "common knowledge."
• Nondeclaritive memory unconsciously builds up. These include procedural memories, such as riding a bicycle or playing the piano.
