Final answer:
Nondeclarative memory, or implicit memory, includes motor skills and associations learned through practice and repetition.
Step-by-step explanation:
Nondeclarative memory, also known as implicit memory, refers to the type of long-term memory that is not consciously accessible and involves skills and associations that have been learned through practice and repetition. Motor skills, such as riding a bike or playing an instrument, fall under nondeclarative memory as they are acquired through practice and become automatic over time. Similarly, associations between sensory stimuli and learned behavior, like conditioning, are also a part of nondeclarative memory.
