You can picture it as a lens pointed at what goes on inside someone's mind — thoughts, feelings, memories, fears — and how that invisible inner world drives what they actually do. Anything to do with that inner world is 'psychological'.
From the word’s history
From Greek psykhē 'breath, soul, mind' (linked to psykhein 'to breathe'), plus -logy 'the study of'. At root it means 'to do with that invisible, thinking mind' — exactly its modern core.
psychological 的字根是希臘文 psykhē，本意是『氣息、靈魂、心智』（跟 psykhein『吹氣、呼吸』有關），後面接上 -logy『對…的研究』。所以這個字底子裡就是『跟那口看不見、會思考的心智有關』——正好對上它的核心。
