What term pertains to mental processes such as thinking, knowing, remembering, and perceiving?

The term that relates to mental processes like thinking, knowing, remembering, and perceiving is cognitive. Cognitive functions encompass a range of mental activities that allow individuals to process information, solve problems, make decisions, and acquire knowledge. These processes are crucial for day-to-day functioning and learning.

In contrast, emotional refers to feelings and affective responses that may influence a person's mental state but do not directly describe cognitive processes. Behavioral pertains to actions and observable responses rather than internal mental activities. Psychological is a broader term that includes all aspects of mental processes and behavior, but when specifically focusing on the processes of thinking and knowing, cognitive is the more precise term to use. Therefore, cognitive encompasses the specific areas of mental function highlighted in the question.
