Neuroimaging studies demonstrate that moral responsibility judgments activate the social cognition network, presumably reflecting mentalising processes. Conceptually, establishing an agent's intention is a sub-process of responsibility judgment. However, the relationship between both processes on a neural level is poorly understood. To date, neural correlates of responsibility and intention judgments have not been compared directly. The present fMRI study compares neural activation elicited by third-party judgments of responsibility and intention in response to animated pictorial stimuli showing harm events. Our results show that the social cognition network, in particular Angular Gyrus (AG) and right Temporo-Parietal Junction (RTPJ), showed stronger activation during responsibility vs. intention evaluation. No greater activations for the reverse contrast were observed. Our imaging results are consistent with conceptualisations of intention attribution as a sub-process of responsibility judgment. However, they question whether the activation of the social cognition network, particularly AG/RTPJ, during responsibility judgment is limited to intention evaluation.
