ONE LAST CC EXAMPLE
CLICKER QUESTION

A.
B.
C.
D.
As a child, you were playing in the yard one day
when a neighbor’s cat wandered over. Your
mother screamed and brought you inside. Her
behavior caused you to cry. You now have a fear
of cats. The unconditioned stimulus (UCS) is
Your mother’s behavior.
Your crying.
The cat.
Your fear of cats today.
