Neural Correlates of Belief Attribution and Inhibition
Department of Psychiatry, MedBo GmbH Regensburg
Supervisor: Prof. Dr. Göran Hajak , Dr Monika Sommer, Dipl.psych. Katrin Döhnel

Summary: The concept of having a Theory of Mind (ToM) originally comes from the field of developmental psychology, referring to the ability to represent false beliefs, which is the ability to recognize that others can have beliefs about the world that are not corresponding to reality. The acid test for investigating the ability to attribute beliefs is the true belief/false belief task (FB/TB task). During this task the participants have to select among interfering responses concerning true or false mental representations of the reality. Interestingly, in children the ability to understand false belief develops to the same time as inhibitory control. This issue has been intensively studied in behavioural and, during the last decade, also neuroimaging studies and raised the question, if belief attribution (as the crucial part of Theory of Mind) and cortical inhibition, needed to suppress a prepotent response, are supported by overlapping brain areas. Possible candidate regions seem to be the dorsal medial prefrontal cortex (including the dorsal anterior cingulate cortex) and the right temporo-parietal junction. But so far, only one experiment was performed investigating belief attribution and inhibition in the same session using equal stimuli (Rothmayr, Dissertation). The present functional Magnetic Resonance Imaging (fMRI) study used the same complex social stimuli to compare activation in the following two tasks: 1) 14 volunteers performed a modified Theory of Mind task, originally known from developmental psychology studies (Sally-Anne-Paradigm; Baron-Cohen et al., 1985), tapping belief attribution by comparing stories involving another person’s false belief with stories involving another person’s true belief; 2) A Simon task, originally invented to study response-based conflicts caused by interfering response possibilities. For this latter experiment a total of 28 volunteers participated out of which 16 performed the task while being in the MRI scanner.

False belief over true belief revealed activation in the medial prefrontal cortex (BA 8; including the dorsal anterior cingulated cortex; BA 32), the dorsolateral prefrontal cortex (BA 9) and the temporo-parietal junction bilaterally (BA39/40). Resolution of the response-based conflict (incompatible trials > compatible trials) was distinguished by activity in the frontal eye field (BA 8), the visual cortex (BA 18/19), the right temporo-parietal junction (BA 39), as well as in parts of the ventrolateral prefrontal cortex (BA 38/47). The graphical overlap of the results revealed non-overlapping regions for false belief and inhibition in the dorsomedial prefrontal cortex (BA 8/32) and in the right temporo-parietal junction (BA 39).
Present results suggest that the inhibition mechanism necessary to decouple mental states from reality is not exactly the same inhibitory mechanism recruited by the response-based conflict during incompatible trials in the Simon task. This suggests for further developmental psychology research to accurately distinguish between different inhibitory mechanism and even more important to focus on more basal processes in search of a common core mechanism between belief attribution and inhibition.
