The behaviorist movement in psychology in the early 1900s provided a number of benefits. The behaviorists’ precise measurement of stimulus and response lent psychology a scientific cachet. And precise measurement led to the development of the technology of behavior control that has been quite valuable in a practical sense.At the same time, the decision to ignore the subjective experience of animals introduced unnecessary confusion about our behavior. The behaviorists mistakenly believed that the power to shape habits lay outside the animal, in an objectively defined “reinforcer.” But that wasn’t true at all. The animal’s experience of satisfaction is a direct reflection of its inborn drives – the biology underlying its behavior. The same external stimulus could be reinforcing or not depending on the animal’s drive-based interpretation. And that interpretation varied wildly depending upon the environment within which the stimulus occurs. This fact is tremendously important for our understanding and treatment of unwanted habits – including addictions. To illustrate, Bruce Alexander’s “Rat Park” experiments convincingly demonstrated that rats are far more likely to use addictive substances when confined to cramped laboratory cages than they are when housed in richer environments. The implications for humans are profound: It's likely that our environments are a more important factor in the development of addiction than is the addictive substance.In this podcast Deep Divers Mark and Jenna engage in a lively discussion of this topic, and conclude with a message of hope.
