Humans display a strong tendency to make spontaneous inferences concerning the thoughts and intentions of others. Although this ability relies upon the concerted effort of multiple brain regions, the dorsal medial prefrontal cortex (DMPFC) is most closely associated with the ability to reason about other people's mental states and form impressions of their character. Here, we investigated this region's putative social category preference using fMRI as 34 participants engaged in uninstructed viewing of a complex naturalistic stimulus. Using a data-driven “reverse correlation” approach, we characterize the DMPFC's stimulus response profile from ongoing neural responses to a dynamic movie stimulus. Results of this analysis demonstrate that the DMPFC's response profile is dominated by the presence of scenes involving social interactions between characters. Subsequent content analysis of video clips created from this response profile confirmed this finding. In contrast, regions of the inferotemporal and parietal cortex were selectively tuned to faces and actions, both features that often covary with social interaction but may be difficult to disentangle using standard event-related approaches. Together, these findings suggest that the DMPFC is finely tuned for processing social interaction above other categories and that this preference is maintained during unrestricted viewing of complex natural stimuli such as movies.

"Finally, a study published in the Journal of Neuroscience found that introverts had larger, thicker gray matter in their prefrontal cortex — the area of the brain associated with abstract thought and decision-making. Extroverts had thinner gray matter in that same area. This suggests that introverts may devote more neural resources to abstract thought, while extroverts tend to live in the moment more."

"The inner ring: abstract versus concrete
According to Keirsey, everyone can engage in both observation and introspection. When people touch objects, watch a basketball game, taste food, or otherwise perceive the world through their senses, they are observant. When people reflect and focus on their internal world, they are introspective. However, individuals cannot engage in observation and introspection at the same time. The extent to which people are more observant or introspective directly affects their behavior.
People who are generally observant are more 'down to earth.' They are more concrete in their worldview and tend to focus on practical matters such as food, shelter, and their immediate relationships. Carl Jung used the word sensation when describing people who prefer concrete perception. People who are generally introspective are more 'head in the clouds.' They are more abstract in their world view and tend to focus on global or theoretical issues such as equality or engineering. Carl Jung used the word intuition when describing people who prefer abstract conception."
