Were you embarrassed when learning to square dance to the sound of country music? Was your best friend in kindergarten from India? Did your loving mother always purchase Skippy peanut butter? What kind of music do you detest? With which other nationality of people do you choose to affiliate? What is your favorite brand of peanut butter? These are surely not inborn preferences, but arise from your own highly personal experiences. Our likes and dislikes, our mercies and prejudices – whether or not we are consciously aware of them – are also learned through the basic mechanisms of Pavlovian conditioning. Associative learning lies at the heart of our many emotional – or, as psychologists call them, affective – reactions. Such forewarning not only encourages beneficial overt action it also triggers the kinds of emotional responses that the above political commentators stressed. Wellcome Trust, CC BY Beyond overt responses to emotional reactions These associations play out in people in more complicated ways than Pavlov could measure in his dogs via salivary gland output. Such clearly adaptive actions tell a very different tale about associative learning than is popularly portrayed: Forewarned is most assuredly forearmed. These signals enable us to respond appropriately: to seek shelter from the impending storm, to lower the volume of the audio system and to head to the front door. Pavlov simply studied the response system he knew best indeed, he earned the Nobel Prize in 1904 for his work in digestive physiology.Īfter more than a century of scientific study, we now understand that basic associative learning – sometimes called Pavlovian or classical conditioning – is the essential process responsible for our anticipating one event from the occurrence of another: as when the flash of lightning portends the clap of thunder, when the peaceful ending of the symphony’s third movement cues the raucous opening of the fourth movement and when the chime of the doorbell heralds the arrival of the first dinner guest. Rather, he saw the potential for such learning to be part of a broad range of adaptive human actions. Critically, Pavlov did not study salivation in dogs because he believed associative learning to be an inherently primitive process applicable only to mechanical reactions in animals. Pavlov’s great scientific achievement was to objectively and experimentally investigate these laws. Pavlov with three colleagues operating on a dog. British philosophers including John Locke, David Hume and David Hartley had, based on their own keen observations and introspections, outlined basic associative laws by which one event comes to suggest another. When one thing gets linked to anotherĪssociative learning was recognized and appreciated long before Pavlov initiated his pioneering scientific studies. Nothing in these pejorative remarks hints at how associative learning contributes to performing responses that help us survive and thrive. People were reduced to canines and their reactions downgraded to mechanical reflexes. Remember, Pavlov’s own breakthrough was discovering that dogs could learn to associate the dinner bell with the meal itself and so begin to drool when the bell rang in advance of when the feeding bowl was actually placed within reach.īut, these commentators cast such learned associations in a decidedly negative light. Right?”Įach remark contains a profound truth: Extremely strong associations can indeed be formed between events. And, so he is Pavlov and we are all the dogs.
