Does reinforcement history or emotion/instinct drive behavior? Both. Emotion drives “behavior” - the general category of things we do. And reinforcement history drives the specific behavior which the learner chooses, from amongst all of the available options. The challenge here is that the word “behavior” means both the general category and a specific choice of a specific behavior. Both are happening. I spend a few extra minutes talking about this during this live. Plus - note how adorable my dog is. I mean…I can barely stand his cuteness!
