Which term refers to unconscious skills and habits in memory?

The term that refers to unconscious skills and habits in memory is nondeclarative memory. This type of memory is involved in tasks that can be performed automatically and without conscious thought, such as riding a bike, driving a car, or typing on a keyboard. Nondeclarative memory encompasses procedural memories, which are learned behaviors and skills that become automatic through practice.

In contrast to nondeclarative memory, declarative memory includes facts and events that can be consciously recalled and articulated. Declarative memory is further divided into episodic memory, which pertains to personal experiences and specific events, and semantic memory, which relates to general knowledge and concepts. These types of memory require conscious thought and awareness, distinguishing them from the automatic and unconscious nature of nondeclarative memory.
