P: Philosophical zombie Wikipedia.org/wiki/Philosophical_zombie

A philosophical zombie or p-zombie is a hypothetical being that is indistinguishable from a normal human being except that it lacks conscious experience, qualia, or sentience. When a zombie is poked with a sharp object, for example, it does not feel any pain. While it behaves exactly as if it does feel pain (it may say "ouch" and recoil from the stimulus, or tell us that it is in intense pain), it does not actually have the experience of pain as a putative 'normal' person does. The notion of a philosophical zombie is mainly a thought experiment used in arguments (often called zombie arguments) in the philosophy of mind, particularly arguments against forms of physicalism, such as materialism and behaviorism.
