Classical Conditioning is the term normally used to describe the associative learning process first explored by Pavlov
in his experiments with dogs.
Classical conditioning describes the ability of an animal to learn (be "conditioned") to associate a new stimulus for which it has no inherent response, with a stimulus to which it responds inherently.
The stimulus that the animal must learn to respond to is called the conditioned stimulus
and its learned response to it is called a conditioned response
The stimulus the animal inherently knows how to respond to is called the unconditioned stimulus
, and its inherently known response to it is called an unconditioned response
An Unconditioned Stimulus is a stimulus which
evokes a hard-wired, inherent response from
the animal. In other words, the animal
did not have to learn the behavior, and
responds to US based on knowledge it
has at birth.
A Conditioned Stimulus is a stimulus for which
there is no hard-wired, inherent response.
This describes behavior that the animal is not
born with and must learn. In other words, the
animal must be conditioned to
respond to CS.
An Unconditioned Response is a response
to stimulus that is hard-wired in the animal from
Unconditioned Responses do
not need to be learned (the animal does not need to
be conditioned to produce the response).
A Conditioned Response is one that
must be taught to the animal. In other words,
the animal must be conditioned to produce the
