Exposure to stressful life events is another important risk factor for MDD. However, the mechanisms linking reward-deficit and stress to MDD remain poorly understood. Here,...

BACKGROUND: Previous studies using neuroimaging and behavioral measures reported altered reward processing in anorexia nervosa (AN). In addition, anhedonia states are frequently reported in AN, potentially due to the physiological stress produced by the permanent starvation. We investigated the effect of fasting and satiety on mood and reaction times to monetary rewards in AN patients and healthy...

Impaired decision-making under conditions of uncertainty seems to contribute to theexpression and maintenance of anorexia nervosa (AN), but it is not clear whether thisimpairment is a disease state that would remit with treatment, or a persisting trait inpatients with AN. To examine this question, a longitudinal study was conducted in12 female inpatients with AN (age M = 22.2, SE = 1.36), before...

Introduction: Reward and stress are important determinants of motivated behaviors. Striatal regions play a crucial role in both motivation and hedonic processes. So far, little is known on how cognitive effort interacts with stress to modulate reward processes. This study examines how cognitive effort (load) interacts with an unpredictable acute stressor (threat-of-shock) to modulate motivational...

Cognitive, behavioral, and mindfulness-based stress prevention programs were shown to reduce symptoms of anxiety, depression, and perceived stress in university students. However, little is known of their effect on resource activation. Additionally, most...
