“…Depressed and dysphoric individuals anticipate and experience less pleasure concerning a variety of activities and hedonic consequences, attribute lower value to rewards, and report weaker approach motivation (e.g., Dickson & MacLeod, 2006;Kasch, Rottenberg, Arnow, & Gotlib, 2002;MacPhillamy & Lewinsohn, 1974). On a behavioral level, depressed and dysphoric individuals fail to develop a response bias toward the rewarded or more frequently reinforced stimulus, fail to choose the options maximizing their winnings, and show deficits in reward-based decision making (e.g., Forbes, Shaw, & Dahl, 2007;Henriques & Davidson, 2000;Kunisato et al, 2012;Liu et al, 2011;Pizzagalli, Iosifescu, et al, 2009;Pizzagalli et al, 2005). Finally, a number of recent studies demonstrated reduced activity in cortical and subcortical components of the neural reward circuit of depressed and dysphoric individuals, both during anticipation and outcome phases of reward processing (e.g., Forbes et al, 2009;Knutson et al, 2008;Pizzagalli, Holmes, et al, 2009;Smoski et al, 2009;Steele, Kumar, & Ebmeier, 2007).…”
