“…Each model included crossed random effects for subjects and fixed effects for MMS similarity (z-scored), rs-FC similarity (zscored) and their interaction, with mentalising similarity (z-scored) as the outcome variable. social interactions, such as trust or deception (Eskander et al, 2020;Haas et al, 2015;Koscik & Tranel, 2011;Santos et al, 2016). In concert with these studies, our result suggests a close link between OS, a higher-order mentalising component for the rich and complex social life, and the amygdala.…”

“…Third, the variation of OS presented greater representational similarity to individual variation in amygdala MMS or rs‐FC relative to hippocampal MMS or rs‐FC. A plethora of literature has illustrated the importance of the amygdala in mentalising (Rice et al, 2014 ; Stone et al, 2003 ), especially in complex social interactions, such as trust or deception (Eskander et al, 2020 ; Haas et al, 2015 ; Koscik & Tranel, 2011 ; Santos et al, 2016 ).

While for OS (the ability to see “ourselves from the outside” [Asen & Fonagy, 2012 ]), a higher‐order mentalising component for complex social interactions, especially for trust or deception (Wu et al, 2022 ), we speculated that the amygdala would show a closer link to this component based on the indispensable role of the amygdala in developing and expressing interpersonal trust (Eskander et al, 2020 ; Haas et al, 2015 ; Koscik & Tranel, 2011 ; Santos et al, 2016 ).…”

Every individual makes a difference: A trinity derived from linking individual brain morphometry, connectivity and mentalising ability

Mentalising ability, indexed as the ability to understand others' beliefs, feelings, intentions, thoughts and traits, is a pivotal and fundamental component of human social cognition. However, considering the multifaceted nature of mentalising ability, little research has focused on characterising individual differences in different mentalising components. And even less research has been devoted to investigating how the variance in the structural and functional patterns of the amygdala and hippocampus, two vital subcortical regions of the “social brain”, are related to inter‐individual variability in mentalising ability. Here, as a first step toward filling these gaps, we exploited inter‐subject representational similarity analysis (IS‐RSA) to assess relationships between amygdala and hippocampal morphometry (surface‐based multivariate morphometry statistics, MMS), connectivity (resting‐state functional connectivity, rs‐FC) and mentalising ability (interactive mentalisation questionnaire [IMQ] scores) across the participants ( ). In IS‐RSA, we proposed a novel pipeline, that is, computing patching and pooling operations‐based surface distance (CPP‐SD), to obtain a decent representation for high‐dimensional MMS data. On this basis, we found significant correlations (i.e., second‐order isomorphisms) between these three distinct modalities, indicating that a trinity existed in idiosyncratic patterns of brain morphometry, connectivity and mentalising ability. Notably, a region‐related mentalising specificity emerged from these associations: self‐self and self‐other mentalisation are more related to the hippocampus, while other‐self mentalisation shows a closer link with the amygdala. Furthermore, by utilising the dyadic regression analysis, we observed significant interactions such that subject pairs with similar morphometry had even greater mentalising similarity if they were also similar in rs‐FC. Altogether, we demonstrated the feasibility and illustrated the promise of using IS‐RSA to study individual differences, deepening our understanding of how individual brains give rise to their mentalising abilities.

Spirals of Sustainable Academic Motivation, Creativity, and Trust of Higher Education Staff

Sustainability has to penetrate more and more into higher education. It should not focus only on traditional elements. It should also enter new, but for future improvement, extremely important areas. Based on this premise, creativity and motivation, when additionally interconnected and supported by trust that is provided and achieved, decide on the progress and sustainability of universities. This connection is gaining importance especially from the point of view of building solid foundations and mechanisms that functionally preserve the potential effects of these elements in the future. For this reason and following the nature, importance, and content of sustainable academic motivation (SAM), the paper introduces two new concepts: sustainable academic creativity (SAC) and sustainable academic trust (SAT). For further original contributions, the paper hypothesizes the existence of mutual—spiral—relations of sustainable academic motivation (SAM), sustainable academic creativity (SAC), and sustainable academic trust (SAT). The empirical section tests the validity of this claim in the universities of two countries: the Slovak Republic and Poland. A survey performed on a sample of n=181 pedagogical, scientific, management, and administrative staff in higher education confirms the existence of these spirals. The results indicate the spiral effect of motivation when connected with creativity and trust and show that it is accented by the crucial principles of sustainability (responsibility, novelty, usefulness, progress, etc.). Therefore, the paper’s conclusion contains the explanations for the potential occurrence of three types of sustainably mutual systems and complexes. These are: (a) individual sustainable systems of SAM, SAC, and SAT; (b) group/sectional sustainable systems of SAM, SAC, and SAT; and (c) the global sustainable complex of SAM, SAC, and SAT in the university.
