3. Psychologists like to experiment on other organisms in their immediate environment, so Jenny decided to perform a few experiments on her kitty, Precious. Jenny had a little clicker that makes
a loud 'CLICK' sound. She walked around the house, randomly clicking it while Precious rested in
the living room. Then Jenny sat down with Precious, and used the flash on her camera to flash a
bright light at the same time she clicked. Precious blinked because of the flash, and looked mildly
annoyed. Jenny repeated this process with her 4 times, then clicked the clicker, without using the
flash. She still blinked!
