Classical conditioning occurs when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US). Usually, the conditioned stimulus is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).
It may also be called "conditioned suppression" or "conditioned fear response (CFR)." [1] It is an "emotional response" that results from classical conditioning, usually from the association of a relatively neutral stimulus with a painful or fear-inducing unconditional stimulus. As a result, the formerly neutral stimulus elicits fear.
The order in which stimuli are presented is an important factor in all forms of classical conditioning. Forward conditioning describes a presentation format in which the CS precedes the US in time. That is, from the perspective of the research subject, experiencing the US is contingent upon having just experienced the CS.
Human contingency learning has its roots connected to classical conditioning; also referred to as Pavlovian conditioning after the Russian psychologist, Ivan Pavlov. [5] It is a type of learning through association where two stimuli are linked to create a new response in an animal or person. [3]
B. F. Skinner's classification system of human language in behavior analysis has been applied to treatment of a host of communication disorders. [73] Skinner's system includes: Tact – a verbal response evoked by a non-verbal antecedent and maintained by generalized conditioned reinforcement (e.g., identifying items, people, or nonhuman animals).
Human beings have an innate resistance to killing and are reluctant to act in a direct, aggressive way towards members of their own species, even to save life. This resistance to killing has caused infantry to be remarkably inefficient throughout the history of military warfare.
The unconditioned stimulus is the dog's food that would naturally cause salivation, which is an unconditioned response. Pavlov then trained the dog by ringing the bell every time before food. The conditioned stimulus is the ringing bell after training, which causes salivation as a conditioned response. [3] [page needed]
One significant example of classical conditioning is Ivan Pavlov's experiment in which dogs showed a conditioned response to a bell the experimenters had purposely tried to associate with feeding time. After the dogs had been conditioned, the dogs no longer only salivated for the food, which was a biological need and therefore an unconditioned ...
