Final answer:
Non-Declarative or Implicit Long-Term Memory mainly deals with unconscious learning and skill acquisition, such as riding a bike or typing, which are retained and performed without active recall.
Step-by-step explanation:
Understanding Non-Declarative/Implicit Long-Term Memory
Non-Declarative or Implicit Long-Term Memory primarily involves b) Unconscious learning and skill acquisition. This form of memory includes procedural memory and things learned through conditioning. Unlike explicit memory, which requires conscious recall of facts and events, implicit memory is demonstrated when performing tasks and does not enter our conscious awareness. It is akin to a program running in the background of our cognitive processes. Because of its nature, implicit memories are not easily described in words and are acquired outside of our direct awareness.
Examples of implicit memory include riding a bike or typing on a keyboard, which once learned, do not require conscious thought to execute. Such skills are retained in the long term and can be performed without active recall, showcasing the role of implicit memory in unconscious learning and skill acquisition.
