Correlations of ventral striatal cue-reactivity with amount of pornography use, frequency of masturbation, and clinical features of PPU. The correlations between differential striatal reactivity to monetary vs erotic cues and (a) relative motivation index measured as difference between RTs for monetary–erotic trials; (b) severity of CSB measured by the Sexual Addictions Screening Test—Revised (20 points scale, which was not used at recruitment phase); (c) average amount of pornography consumption per week, and (d) frequency of masturbation per week. Error lines depicts 95% confidence intervals. Bonferroni–Holms correction was used for multiple comparisons. CSub, control subjects; PPU, problematic pornography users.
