A Behavioral Neuroscience Perspective on the Will

In Effort: A Behavioral Neuroscience Perspective on the Will, author Jay Schulkin presents a two-fold thesis: there is no absolute separation of the cognitive and non-cognitive brain, and there are diverse cognitive systems, many of which are embodied in motor systems that underlie self-regulation. Central to this thesis is that dopamine is the one neurotransmitter that underlies the diverse senses of effort, and is apparent in most everyday activity, whether solving a problem in our head or moving about.
As scientific literature abounds with studies of decision-making and effort, this book emphasizes the importance of demythologizing our understanding of cognitive systems in order to link motivation, behavioral inhibition, self-regulation, and will.
Effort will benefit researchers and students in neuroscience, behavioral neuroscience, cognitive psychology, clinical psychology, social psychology, as well as anyone with interest in this topic.
