A new study shows that updating beliefs about the world requires and stimulates dopamine release in the brain.
Lead author of the study, Matthew Nour, from University College London and Kings College London has this to say about the findings:
“We found that two key brain areas of the dopamine system (the midbrain and striatum) appear to be more active when a person updates their beliefs about the world, and this activity is related to measures of dopamine function in these regions.” (Source)
Healthy people update beliefs when new evidence is presented. The study may also show that abnormal dopamine functionality is implicated in schizophrenia and paranoid ideation by interfering with normal updating.
The study can be found here: Dopaminergic basis for signaling belief updates, but not surprise, and the link to paranoia.
I like this study because participants were measured while changing minor, short-term beliefs.
Small changes in beliefs manifested in short-term memory lies at the heart of FIML practice.
FIML relies heavily on changing inaccuracies in the short-term memory bank because this data can be isolated and objectively agreed upon by both partners and because this data is by definition fairly small and thus easily changed.
A year of FIML practice may entail a thousand or more small updates in perception, belief, and self-knowledge. Each individual update is typically small, but the aggregate of many updates over longer periods of time creates the basis for very large psychological transformations.
And since these transformations are based on more accurate data, they lead to a more realistic view of the world and the self.
Moreover, by regularly making many small updates in their perceptions of each other and themselves, FIML partners are constantly exercising their dopamine “updating system,” thus strengthening their abilities to function well in any environment.
FIML changes can come quickly, but it is long-term practice that brings the best results.
The above study shows that something very real happens when we update our perceptions. I would maintain that making this happen often with meaningful psychological information through FIML practice leads to very significant and beneficial changes in psychological functioning across many domains.
