“…Our findings thus suggest that the posterior cerebellum is involved in utilizing internal models not only at a lower level of sequences, but also at a higher level of social actions that do, or do not, conform to social norms. This finding was also observed in earlier studies by Pu and colleagues on inconsistencies between actual behaviors and predictions based on personality traits ( Pu et al ., 2021 , 2022a , 2022c ). This is in line with a broad theoretical understanding of the cerebellum in facilitating swift adaptive behavior, because norm violations also require changing the sequential dynamics of social interactions.…”

“…social sequencing), which could be perceived as more routine and less attention-grabbing. Although not predicted by the ‘sequencing hypothesis’ ( M. G. Leggio et al ., 2011 ), this priority aligns with the broader notion that the main role of the social cerebellum is to identify deviations from predictions, as in previous studies on trait and stereotype inconsistencies mentioned earlier ( Pu et al ., 2021 , 2022a , 2022c ).…”

“…Recent fMRI (functional magnetic resonance imaging) studies consistently showed that the posterior cerebellum (areas Crus 1 & 2) is involved in social navigation ( Li et al ., 2021 , 2022 ) as well as in other social sequences ( Van Overwalle et al ., 2019a , 2021 ; Pu et al ., 2022a ; Ma et al ., 2023 ). A clinical study documented that cerebellar patient showed deficits in reproducing previously presented steps in a sequence-based navigation task ( Tedesco et al ., 2017 ).…”

Social norms are pivotal in guiding social interactions. The current study investigated the potential contribution of the posterior cerebellum, a critical region involved in perceiving and comprehending the sequential dynamics of social actions, in detecting actions that either conform to or deviate from social norms. Participants engaged in a goal-directed task in which they observed others navigating towards a goal. The trajectories demonstrated either norm-violating (trespassing forbidden zones) or norm-following behaviors (avoiding forbidden zones). Results revealed that observing social norm-violating behaviors engaged the bilateral posterior cerebellar Crus 2 and the right temporoparietal junction (TPJ) from the mentalizing network, and the parahippocampal gyrus (PHG) to a greater extent than observing norm-following behaviors. These mentalizing regions were also activated when comparing social sequences against non-social and non-sequential control conditions. Reproducing norm-violating social trajectories observed earlier, activated the left cerebellar Crus 2 and the right PHG compared to reproducing norm-following trajectories. These findings illuminate the neural mechanisms in the cerebellum associated with detecting norm transgressions during social navigation, emphasizing the role of the posterior cerebellum in detecting and signaling deviations from anticipated sequences.

Prior studies suggest that the cerebellum contributes to the prediction of action sequences as well as the detection of social violations. In this dynamic causal modeling study, we explored the effective connectivity of the cerebellum with the cerebrum in processing social action sequences. A first model aimed to explore functional cerebello-cerebral connectivity when learning trait/stereotype-implying action sequences. We found many significant bidirectional connectivities between mentalizing areas of the cerebellum and the cerebrum including the temporo-parietal junction (TPJ) and medial prefrontal cortex (mPFC). Within the cerebrum, we found significant connectivity between the right TPJ and the mPFC, and between the TPJ bilaterally. A second model aimed to investigate cerebello-cerebral connectivity when conflicting information arises. We found many significant closed loops between the cerebellum and cerebral mentalizing (e.g. dorsal mPFC) and executive control areas (e.g. medial and lateral prefrontal cortices). Additional closed loops were found within the cerebral mentalizing and executive networks. The current results confirm prior research on effective connectivity linking the cerebellum with mentalizing areas in the cerebrum for predicting social sequences, and extend it to cerebral executive areas for social violations. Overall, this study emphasizes the critical role of cerebello-cerebral connectivity in understanding social sequences.
