Instinctive response is an innate response that does not need to be learned or imitated. It is generally an unconditioned response that is controlled by the viscera or the autonomic nerve or the extravertebral system.
In addition, the instinctive response is interpreted as not thinking through the brain. For example, there will be an avoidance response when being stimulated by external pain. This situation will not be thought through the brain, but can be reflected through the reflex center of the spinal cord. When the hand is burned, the first thing is to retract the hand reflexively instead of feeling pain. This is an instinctive reaction, a relatively primitive reaction, a reaction through the inferior center, and a self reaction of the internal organs or limbs.
