Thanks for sharing! When I took the psychology module in my uni days, classical conditioning was one of the topics that really left a deep impression in me. At that time, I started to think of the small things in life that we had unknowingly conditioned to. For example, red is associated to danger while on the road and a slight sense of pain and fear is felt when you see a needle at the clinic.

The other concept which I still remember is Skinner's Operant Conditioning. It is probably one of the most used learning/teaching techniques in our daily life. Haha..
