My name is Dorien Enter, and I am working as a PhD candidate in Experimental Psychopathology at the Behavioral Science Institute, where I moved after graduating in Biology (Experimental Psychobiology) at Utrecht University. I am interested in individual differences in the neuroendocrinological regulation of social motivational behavior. My PhD research focuses on the role of the gonadal hormone testosterone in social fear and avoidance in patients with Social Anxiety Disorder (SAD). Several measures are involved, including tracking of eye gaze behavior, facial mimicry (EMG), neural correlates of motivational processing (EEG/ERP), behavioural approach-avoidance action-tendencies, and social punishment-reward sensitivity.
