People receiving chemotherapy often vomit during or shortly after the procedure. after several chemotherapy sessions, they begin to feel nauseous as they enter the treatment room.
label the following:
ns, ucs, cs, ucr, cr.

NS- entering the room

UCS- receives chemo

CS-entering the room

UCR- feel sick

CR-feel sick

Explanation:

At first a person receives a natural uncontioned stimulus (UCS) which is chemotherapy which result to a person getting automatically sick , this isn't a learnt response it just happens naturally, we call this feeling sick after receiving a chemotherapy as unconditioned response (UCR) because it is a response to an unconditioned stimulus (chemotherapy)

The room where one receives therapy becomes a previously neutral stimulus (NS) over time it will start to trigger the same effect as that one triggered by the UCS when it start to do that it becomes a conditioned stimulus (CS) and the response it triggers is known as conditioned response (CR) because it is no longer occuring naturally but with a learned behavior of associating the room with chemotherapy.
