We've definitely covered a lot of material over the last semester. Looking back, I think that the concept I will most likely remember is classical conditioning.
Like most people I'm sure, I had heard of Pavlov previous to taking this course; it wasn't until we learned about this concept that I realized just how pervasive classical conditioning is in everyday life. Perhaps one of the most obvious ways in which classical conditioning is utilized is in advertising (which just so happens to be my major).
Advertising relies heavily on the use of classical conditioning to associate products with certain thoughts and emotions, demonstrating just how powerful our emotions are in affecting our behavior.
It explains why ads typically show attractive models with minimal clothing - despite the fact that the ad may be for a clothing store.
Yet tactics like this must be successful, because it's a technique that is repeated over and over. This technique has added depth to the way in which I analyze and understand how advertising works.
