Pavlov's Dogs.

Ivan Pavlov was a Russian Mathematician, but I believe he is most famous for his study on the psychological phenomenon of conditioned response.

A stimulus (a change in the environment) causes particular reflex responses. But animals learn to produce the same response to new stimulus'.

Pavlov discovered that dogs would salivate every time they smelt food, this is a reflex response. Pavlov experimented by ringing a bell before the dogs were given their food. After repeating this experiment for a while, Pavlov noticed that the dogs would salivate every time they heard the bell ring. This is a conditioned reflex.

What does Pavlov's Dog have to do with this blog? I hear you ask. Absolutely nothing.

The only reason I am posting a blog about it is because my Biology teacher told us that writing things down helps us remember things.

So thank you Justified Confusion, you're helping me pass a GCSE Biology Exam.
