OK, the response is pretty much the same, however, the stimulus it is in response to is different.
VCAA 2007 Exam:
Question 7
Marnie is a nurse at a country hospital. Jimmy, an 8-year-old boy, attends the hospital each fortnight for treatment.
On his first visit, Marnie gave him an injection which was very painful. Now he screams when he is approached by a nurse, even if he does not need an injection.
According to the classical conditioning model of learning, identify the
i. unconditioned stimulus
ii. conditioned stimulus
iii. unconditioned response
iv. conditioned response
The answers stated that:
7i. Pain from the needle (pain)
7ii. Approach of nurse (nurse/sight of approaching nurse)
7iii. Fear of pain from injection (scream because of pain)
7iv. Fear of nurse (scream at approach of nurse)
Hence the conditioned response is, well, in response do a different stimulus than the unconditioned response.
The conditioned response is the reaction produced by a stimulus that did not formerly trigger that response, where as the unconditioned response is an automatic response to a stimulus.
Does that make sense?
