This is: Book summary: Unlocking the Emotional Brain, published by Kaj_Sotala on the LessWrong.
If the thesis in Unlocking the Emotional Brain (UtEB) is even half-right, it may be one of the most important books that I have read. Written by the psychotherapists Bruce Ecker, Robin Ticic and Laurel Hulley, it claims to offer a neuroscience-grounded, comprehensive model of how effective therapy works. In so doing, it also happens to formulate its theory in terms of belief updating, helping explain how the brain models the world and what kinds of techniques allow us to actually change our minds. Furthermore, if UtEB is correct, it also explains why rationalist techniques such as Internal Double Crux [1 2 3] work.
UtEB’s premise is that much if not most of our behavior is driven by emotional learning. Intense emotions generate unconscious predictive models of how the world functions and what caused those emotions to occur. The brain then uses those models to guide our future behavior. Emotional issues and seemingly irrational behaviors are generated from implicit world-models (schemas) which have been formed in response to various external challenges. Each schema contains memories relating to times when the challenge has been encountered and mental structures describing both the problem and a solution to it.
According to the authors, the key for updating such schemas involves a process of memory reconsolidation, originally identified in neuroscience. The emotional brain’s learnings are usually locked and not modifiable. However, once an emotional schema is activated, it is possible to simultaneously bring into awareness knowledge contradicting the active schema. When this happens, the information contained in the schema can be overwritten by the new knowledge.
While I am not convinced that the authors are entirely right, many of the book’s claims definitely feel like they are pointing in the right direction. I will discuss some of my caveats and reservations after summarizing some of the book’s claims in general. I also consider its model in the light of an issue of a psychology/cognitive science journal devoted to discussing a very similar hypothesis.
Emotional learning
In UtEB’s model, emotional learning forms the foundation of much of our behavior. It sets our basic understanding about what situations are safe or unsafe, desirable or undesirable. The authors do not quite say it explicitly, but the general feeling I get is that the subcortical emotional processes set many of the priorities for what we want to achieve, with higher cognitive functions then trying to figure out how to achieve it - often remaining unaware of what exactly they are doing.
UtEB’s first detailed example of an emotional schema comes from the case study of a man in his thirties they call Richard. He had been consistently successful and admired at work, but still suffered from serious self-doubt and low confidence at his job. On occasions such as daily technical meetings, when he considered saying something, he experienced thoughts including “Who am I to think I know what’s right?”, “This could be wrong” and “Watch out - don’t go out on a limb”. These prevented him from expressing any opinions.
From the point of view of the authors, these thoughts have a definite cause - Richard has “emotional learnings according to which it is adaptively necessary to go into negative thoughts and feelings towards [himself].” The self-doubts are a strategy which his emotional brain has generated for solving some particular problem.
Richard’s therapist guided Richard to imagine what it would feel like if he was at one of his work meetings, made useful comments, and felt confident in his knowledge while doing so. This was intended to elicit information about what Richard’s emotional brain predicted would happen if it failed ...
