Anxiety and depression are highly prevalent, recurrent, and major public health problems. Decades of research has uncovered associations between symptom dimensions of anxiety and depression and abnormal neural activation across executive control-, threat-, and reward-related networks. Recent studies have developed a hierarchical symptom structure of anxiety and depression termed the...
Decision making is an essential and indispensable element in everyday life. It is posited that parallel, distinct systems subserving deliberative, goal-directed control and automatic, habitual control underlie decision making. Computational accounts suggest that model-based and model-free learning strategies give rise to these two systems respectively. The model-based system is a...
Background: Major Depressive Disorder (MDD) is a significant public health issue. Previous research on the pathophysiology of depression in adults has demonstrated abnormal neural processing associated with depression symptomatology including alterations in reward and aversion circuits. Loss aversion (LA), or the concept that individuals evaluate outcomes based on losses and...
