Reward processing deficits have been implicated in the etiology of depression. A blunted reward positivity (RewP), an event-related potential elicited by feedback to monetary gain relative to loss, predicts new onsets and increases in depression symptoms. Etiological models of depression also highlight stressful life events. However, no studies hav...
Objective : The aim of the current research was to identify the extent to which reward sensitivity and impulsivity were related to food addiction. Method : Forty-five studies, published from 2009 to June 2019, investigating reward sensitivity and/or impulsivity with food addiction as measured by the Yale Food Addiction Scale were reviewed.

This raises the question of why; what are the individual- and situation-level variables that impact a person...
