Actual or perceived controllability over a stressor likely contributes to stress resilience. Three mechanisms are important in this context: stress immunization, learned helplessness and self-efficacy expectancy. C07 will investigate the neural and behavioral correlates of stressor controllability in healthy humans with respect to these three mechanisms. Further, individuals characterized for stress resilience (RT2-score) by central project Z03 will be investigated to test whether the behavioral and neural mechanisms underlying actual and perceived controllability differentiate as a function of resilient outcome.
