Which type of memory is generally described as non-declarative?

Non-declarative memory refers to a type of long-term memory that is not consciously accessible and does not involve intentional recollection or the ability to verbalize the information. Implicit memory, which falls under the category of non-declarative memory, includes skills and actions that we perform unconsciously, such as riding a bicycle or playing a musical instrument. These memories are acquired through experience and practiced over time, allowing individuals to perform tasks without needing to consciously think about them.

In contrast, the other types of memory listed involve conscious recall. For instance, semantic memory relates to factual information and knowledge that can be explicitly stated, while explicit memory encompasses memories that can be deliberately recalled, such as events and facts. Working memory, on the other hand, is a short-term storage system used for mental tasks involving manipulation and processing of information. All these types are declarative and rely on conscious thought processes, distinguishing them from implicit memory. Thus, recognizing implicit memory as a type of non-declarative memory highlights its unique role in our broader understanding of memory systems.
