Extinction: The Role Of Awareness In Classical Conditioning

Register to read the introduction… The conditioned stimulus is followed by an unconditioned stimulus altering with a conditioned stimulus not followed by an unconditioned stimulus. The premise of this phenomenon is that the strength of conditioned response progressively decreases (McSweeny & Bierly, 1984). The deletion of the unconditioned stimulus may cause the conditioned response to wane or discontinue. The unconditioned stimulus is the trigger for the conditioned response, in this case. An example of extinction is a person smokes when in a bar and others are smoking. The same person goes to a bar without smoking and doesn’t …show more content…
This question has been the source of much debate, and there seems to be no clear consensus.
Types of Awareness In order to properly understand the conflicting views, it is important to first clarify what awareness means in the context of classical conditioning. There are two basic types of awareness, external awareness and self awareness (Gorn, Jacobs, & Mana, 1987). External awareness. In a situation of classical conditioning, one form of external awareness is contingency awareness, which is the knowledge of a relationship between the conditioned and unconditioned stimuli (Gorn et al., 1987). Self awareness. Self awareness builds on contingency awareness. A subject is considered self-aware if he realizes that his behavior is a conditioned response to relationship between conditioned and unconditioned stimuli (Gorn et al.,

Those that propose that awareness does not play a role in conditioning point to the behavioral roots of conditioning theory, arguing that cognitive processes can not play a role in what is a purely behavioral mechanism. If any form of awareness is present, they say, classical conditioning is not occurring (Shimp, 1991). To respond to those that say that classical conditioning cannot occur without awareness, they cite chemotherapy-induced taste aversions as a case of classical conditioning where awareness is not present. Patients undergoing chemotherapy (US), which causes nausea (UR), often develop aversions (CR) to foods eaten before a chemotherapy session (CS). Because the source of the food aversions remained a mystery for many years, it is apparent that the patients lacked both self awareness and contingency awareness (Gorn et al.,
