Aversion is a term representing a lack of interest in a specific object. It describes a feeling of unease disliking, distaste, discomfort, or avoidance of a stimulus, a situation, or a behavior.
It is something that comes up often because of experiences that one views as hazardous, and worrying or unwelcoming. It is something that comes up naturally, and one is repulsed by spoiled food because of its taste and or smell, or they have learned this through some form of experience. The instinctive tendency that helps an individual focus on the detection of a threat or an aversive experience is already a primal form of protective behavior of an individual. Sociology shows there is separate clinical meaning to aversion.
In clinical psychology, a method to impose behavioral modification using conditioning is termed aversive behavioral modification. It aims at negative behavioral phenomena like chain smoking or substance dependency, employing discomforting stimuli like extreme heat or blaring sounds.
A sign of advancement in disavow of basic, painful, and the most unwelcomed apparatus in behavioral modification, this goes to say that there is an instinctive connection within the spheres of feelings, cognition and the primal behavior of modern man.
