Final answer:
Declarative memories are conscious memories of facts and events we personally experience, while nondeclarative memories are unconscious memories demonstrated through task performance.
Step-by-step explanation:
Declarative memories, also known as explicit memories, are memories that we consciously try to remember, recall, and report. These memories include facts and events that we personally experience. For example, remembering the capital of the United States is a declarative memory.
On the other hand, nondeclarative memories, also known as implicit memories, are memories that are not part of our consciousness. We cannot consciously recall these memories, but they can be demonstrated through the performance of certain tasks. Examples of nondeclarative memories include procedural memory (such as riding a bike) and memories learned through conditioning (such as a fear response).
