Behavioral results: a) Main effect of difficulty and sexual behavior on the accuracy in the n-back task. Subjects perform worse in the more difficult 2-back condition and controls outperform patients independent of the difficulty. Error bars denotes standard error of the mean (SEM). b) Depicted is the sexual behavior X explicitness interaction on median reaction times showing that patients react slower with distracting pornographic material while no differences with neutral images are detected. Error bars denotes standard error of the mean (SEM). c) Sexual behavior X explicitness interaction for the surprise recognition task. Patients show better memory performance for irrelevant pornographic background pictures while no differences for neutral images could be detected. Error bars denotes standard error of the mean (SEM).
