Many of us are familiar with the famous Pavlov’s Dogs experiment, in which psychologist Ivan Pavlov trained a group of dogs to salivate at the sound of a bell. But did you know he conducted quite a few other experiments before his famous salivating dogs study?

Pavlov’s Giraffes

Pavlov conditioned a group of giraffes to be self-conscious about their weird bodies.

Pavlov’s Worms

Many thought worms did not possesses the mental faculties to be trained to do much of anything, but Pavlov proved the critics wrong. With great determination, he successfully conditioned worms to squirm around a little extra at the sound of a person saying “ew, gross.”

Pavlov’s Other Dogs

Pavlov conditioned dogs to salivate at the sound of a woman’s scream.

He never published this study.

Pavlov’s Penguins

Pavlov attempted to train penguins to begin molting when he turned on an additional lamp. Though this experiment was initially successful, all of the penguins soon died because his lab was too hot.

Pavlov’s Baby

Pavlov conditioned his own baby to salivate whenever someone said the word “Hello.” The child grew up to live a very lonely life.

Pavlov’s Friends

After this long series of aforementioned experiments, Pavlov accidentally conditioned his friends to make up an excuse and leave the room as soon as he entered it.
