Which term refers to the mental activities related to thinking, knowing, and remembering?

The term that encompasses the mental activities related to thinking, knowing, and remembering is "cognition." Cognition refers to all the processes involved in acquiring, processing, and storing information. This includes various functions such as perception, attention, memory, reasoning, and decision-making. It represents a broad range of mental activities that allow individuals to understand and interact with the world around them.

While memory is a crucial aspect of cognition, it specifically pertains to the storage and retrieval of information rather than the entire spectrum of mental processes. Learning, on the other hand, refers primarily to acquiring new information or skills through experience, while thinking generally describes the process of manipulating information—both of these are components of cognition but do not encompass all aspects of it. Therefore, cognition is the most inclusive term capturing the essence of thinking, knowing, and remembering.
