Classical conditioning occurs because the synapses in the neural pathways become strengthened from repeated exposure.
An unconditioned response (such as salivating) is a naturally occurring biological response to an unconditioned stimulus (such as food).
A conditioned stimulus is a previously neutral stimulus (such as a bell) that is paired with an unconditioned stimulus (such as food), in order to elicit a conditioned response (for example, salivating in response to a bell).
An unconditioned response then becomes a conditioned response, associated with a conditioned stimulus, through classical conditioning.
Classical conditioning is a form of learning whereby a conditioned stimulus (CS) becomes associated with an unrelated unconditioned stimulus (US), in order to produce a behavioral response known as a conditioned response (CR).
The conditioned response is the learned response to the previously neutral stimulus.
The unconditioned stimulus is usually a biologically significant stimulus such as food or pain that elicits an unconditioned response (UR) from the start.
The conditioned stimulus is usually neutral and produces no particular response at first, but after conditioning it elicits the conditioned response.
If we look at Pavlov's experiment, discussed in the previous chapter, we can identify these four factors at work:
The unconditioned response was the salivation of dogs in response to seeing or smelling their food.
The unconditioned stimulus was the sight or smell of the food itself.
The conditioned stimulus was the ringing of the bell.
During conditioning, every time the animal was given food, the bell was rung.
This was repeated during several trials.
After some time, the dog learned to associate the ringing of the bell with food and to respond by salivating.
After the conditioning period was finished, the dog would respond by salivating when the bell was rung, even when the unconditioned stimulus (the food) was absent.
The conditioned response, therefore, was the salivation of the dogs in response to the conditioned stimulus (the ringing of the bell) .
Consider how the conditioned response occurs in the brain.
When a dog sees food, the visual and olfactorystimuli send information to the brain through their respective neural pathways, ultimately activating the salivation glands to secrete saliva.
This reaction is a natural biological process as saliva aids in the digestion of food.
When a dog hears a buzzer and at the same time sees food, the auditory stimuli activates the associated neural pathways.
However, since these pathways are being activated at the same time as the other neural pathways, there are weak synapse reactions that occur between the auditory stimuli and the behavioral response.
Over time, these synapses are strengthened so that it only takes the sound of a buzzer to activate the pathway leading to salivation.
