Recently, we learnt classical conditioning in the learning chapter. When we learnt Pavlov's model of classical conditioning, we knew that in first-order conditioning, learning is acquired by pairing a conditioned stimulus (CS) with an intrinsically motivating unconditioned stimulus, for example, like food. In higher-order conditioning, the CS is paired with a another conditioned stimulus that has motivational value that is acquired rather than intrinsic, that is, organisms learn to pair a new CS with the original CS.
Because high-order conditioning helps us to augment CS to new stimuli, we know the reason why we always want to buy a beverage when we see an advertisement. Take the Perrier ad for example, when we see the tennis player in the ad, we have already come to associate the sun, heat, sweat. That makes people feel resonate and thinking about the moment they feel tired and thirsty and they want to buy Perrier.
The professor is "trained" to stand next to the wastebasket in the course in the article is using replicability in the Six Principles of Scientific Thinking. Can the results be duplicated in other studies?
