Which of the following is not a type of long-term memory?

Long-term memory is a type of memory that allows for the storage of information over extended periods, ranging from days to a lifetime. It is divided into several categories, including episodic memory, which pertains to personal experiences and specific events; semantic memory, which involves knowledge about concepts and facts; and motor memory, which relates to the skills and tasks that we learn through practice.

Short-term memory, on the other hand, refers to the limited capacity system that temporarily holds information for a brief period, typically seconds to a minute. It is distinct from long-term memory in both function and duration, as it focuses on the immediate retention of information. Therefore, short-term memory is not categorized as a type of long-term memory, making it the correct answer in this context.
