The concept I learned in psychology that I think I will remember for years to come is classical conditioning. I'm not sure why this is so important to me, maybe it is cause after learning about it I can relate many things to this concept. A simple example that I can think of now for those of you who are athletes and played a sport in high school is, "get on the line." If a random person were told that it wouldn't mean much or trigger any fear. But athletes know that when you here get on the line it means that you are going to be conditioning. This makes "get on the line" a conditioned stimulus with the conditioned response being fear. Classical conditioning is one of the concepts I will never forget because I feel it can relate to situations in my life.
