Which term refers to non-declarative memory that operates without conscious awareness?

The term that refers to non-declarative memory operating without conscious awareness is implicit memory. Implicit memory encompasses skills and behaviors that individuals can perform without actively thinking about them. This type of memory is often demonstrated through actions, such as riding a bike or tying shoelaces, where the individual does not need to consciously recall the steps involved to perform the task successfully.

In contrast, explicit memory involves conscious recall of facts and events, making it declarative in nature. Short-term memory serves as a temporary storage system for information being actively processed, and declarative memory refers to memories that can be consciously recalled, which includes both episodic and semantic memories. Implicit memory, therefore, specifically pertains to those processes that occur automatically and do not require intentional effort or awareness, distinguishing it clearly from the other types mentioned.
