He wholebrain interaction (with MNI coordinates , 42, four), by subtracting the percentage signal
He wholebrain interaction (with MNI coordinates , 42, 4), by subtracting the percentage signal alter in the target sentence in the prime sentence (Figure ). The adaptation index within the vmPFC clearly showed the predicted pattern: the strongest adaptation was identified inside the Comparable situation, becoming nonsignificantly weaker inside the Opposite situation and virtually negligible inside the Irrelevant condition. Post hoc onesided t tests revealed, in comparison with the Irrelevant situation, a stronger adaptation of your Similar situation (P 0.00) and the Opposite situation (P 0.05). There was no difference among the Related and Opposite circumstances (P 0.five). To make sure that the mPFC was involved only in adaptation (i.e. lower of activation), we also performed a wholebrain analysis with the reverse target prime contrast inside the Similar, Opposite and Irrelevant situations. The results revealed a series of brain places that have been extra strongly recruited through the presence of the target sentence amongst the three conditions, including the precuneus, bilateral insula, anterior cingulate cortex, left Methyl linolenate inferior frontal gyrus, left superior parietal cortex, left middle temporal gyrus and suitable lingual gyrus (Table three). Importantly, there was no significant mPFC activation. Trait inference is an essential element of social interactions in our day-to-day life. Neuroimaging research on this subject have implicated the mPFC as an location inside a social mentalizing network that is certainly most primarily involved in trait inference (Ma et al 202b; for a assessment, see Van Overwalle, 2009).
