Sense: noun/1

Thinking is the broadest of these terms and refers to any mental activity — daydreaming, planning, or solving a problem. Reasoning is narrower: it involves moving logically from one idea to another to reach a conclusion. Understanding is the ability to grasp the meaning of something — it is often the outcome of cognition rather than the process itself. Perception is the way the brain takes in information through the five senses; it provides the raw material that cognition then processes and makes sense of. For example, you perceive a red traffic light (perception), but recognising that it means 'stop' and deciding what to do next requires cognition. Cognition is the overarching scientific term for all the mental processes that allow humans to know, learn, and interact with the world.

Etymology

LatinEnglish

Cognition comes from the Latin word cognitio, meaning 'getting to know' or 'acquaintance,' which itself comes from cognoscere — 'to get to know, recognise.' The term entered English in the 15th century through philosophical writing and became a central concept in psychology during the 20th century.
