In this article from the online edition of Psychology Today, researcher Gregory S. Berns discusses the work his research group has completed using positive reinforcement to train dogs to remain still so that an MRI can image their brains. Their latest work involves looking at the parts of the dog’s brain related to impulse control/self-control. This is important work as many behavioral problems in dogs are attributed to being related to poor impulse control.
