A) Effects of various manipulations to increase (green arrows) or decrease (red arrows) large reward preference in probability discounting (PD; St. Onge and Floresco, 2009; Stopper and Floresco, 2011; Wallin et al., 2015). B) AAS decrease dopamine D1 (D1R) and D2 (D2R) receptors in the shell region of the nucleus accumbens (Kindlundh et al., 2001). C) Proposed mechanism for AAS effect on PD. AAS may decrease large reward preference in PD via decreased D1R and/or D2R density in Acb shell.
