Which term refers to something pertaining to the mind?

The term that is most directly related to something pertaining to the mind is "mental." This term is used to describe anything that involves the processes of thinking, reasoning, understanding, and perception which all occur in the mind. It encompasses a wide range of cognitive functions, including memory, attention, and problem-solving abilities.

While "cognitive" also relates to thought processes and understanding, it specifically refers to the mental actions of acquiring knowledge and comprehension. "Psychic" typically refers to phenomena that are beyond normal sensory contact or describe intuitive abilities, rather than the mind's cognitive functions. "Emotional" pertains more to feelings and the affective portion of the mind, which is distinct from mental processes. Therefore, "mental" aligns best with the concept of anything that directly affects or relates to the mind.
