As a former Psych major, I love seeing these things. RSA seems like a particularly good series.
At one point, however, the talk seems to say that the experimental results contradicted behaviorism, since money is a reinforcement. However, there are many reinforcements and punishments. These results seem consistent with Leon Festinger's cognitive dissonance experiments decades ago. Whenever you get beyond simple tasks by simple organisms, there are a lot of things going on, including feedback loops. In my mind, this complexifies behaviorism and makes it more sophisitcated.
