mental content and that that content or knowledge comes from
experience and perception)

2 Types of Conditioning
1) Respondent (AKA classical or pavlovian) = Natural Responses, some
things we encounter in the world naturally elicit (draw out) a response
in us.
2) Operant (AKA Skinnerian or instrumental) = Taught Responding,
when we pair things that don’t have a value
Language of Respondent Conditioning
1) UCS (Unconditioned Stimulus) = Stimulus that elicits a reflective or
innate unconditioned response (UCR) without prior learning.
2) UCR (Unconditioned Response, Natural Response) = Reflexive or
innate response elicited by the UCS without prior learning.
3) CS (Conditioned Stimulus) = Stimulus that through association with
the UCS come to elicit a conditioned response similar to the original
UCR.
4) CR (Conditioned Response) = UCR because have been said to be
automatic or involuntary responses.
