'''Psychological functions''', as described by [[Carl Jung]] in his book ''[[Psychological Types]]'', are particular mental processes within a person's psyche that are present regardless of common circumstances.{{sfn|Jung|1971|loc=chpt. 11}} This is a concept that serves as one of the foundations for his theory on [[personality type]]. In his book, he noted four main psychological functions: ''thinking'', ''feeling'', ''sensation,'' and ''intuition''. He introduced them with having either an internally focused (''[[Extraversion and introversion#Introversion|introverted]]'') or externally focused (''[[Extraversion and introversion#Extraversion|extraverted]]'') tendency which he called "''attitude''". He also categorizes the functions as either ''rational'' (thinking and feeling) or ''irrational'' (intuition and sensation).{{sfn|Jung|1971|loc=chpt. 10}}
