“And because they also observed reductions in amygdala activation, this area associated with threat detection and fear, it's likely, and I should emphasize likely, 'cause I don't know, that the direction of the effect is that there are neural circuit changes, which in turn shift the degree to which t”

Mindsets influence physiology by causing the body to prioritize and prepare for different functions based on core assumptions.

“those mindsets, whether or not they're true or false, right or wrong, they have an impact, and they have an impact not just through the motivational mechanisms that Dweck and others have studied, but as our lab has started to reveal, they also shape physiological mechanisms by changing what our bodi”
