Salivation
Salivation (-minty

BREAKING IT DOWN
Computer beep  no response
 Eating breath mint  salivation (fresh breath)
 Eating breath mint + beep  salivation
Eating breath mint + beep  salivation
Eating breath mint + beep  salivation

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.

IMPORTANCE OF CC

Learning enables animals to become responsive
to adapt to their environments
Other Examples
