Advertising appealing to emotions

I was reading up on people who specialized in the psychology of advertising. I found John B. Watson the founder of behaviorism to be very interesting. Watson believed that in order for advertising to be effective it had to appeal to three emotions which are love, fear, and hate. I think that this concept of ad psychology is very true and that many consumers end up buying a product depending on how it makes them feel. A good example of that is how purfume commericials usually are either sexual, include a fantasy or try to appeal in some part to these emotions. Marketers of the product will put the purfume with a sexy woman that will than make a consumer feel sexy if they buy the product. The sasme effect can be felt with a product like toothpaste, Although toothpaste is not sexy having white teeth is. Ads about toothpaste usually have an attractive person with good teeth and use that to create a need in consumers. People want white teeth and if they believe that the product will deliver the results that they saw in the commercial they will buy it. The product will sell depending on how convicing the commercial is for the consumer. Another psycologists that I discovered that had an impact on ads was Gale Harlow. He was interested in how people process ads and considered the step by step reaction from seeing the ad to purchasing a product. He pretty much believed that advertising had a cycle of effects that eventually led to the purchase of the product.
