One brain region, the right temporoparietal junction, appears to sit at the crossroads of those layers. It coordinates quick matching of others’ movements and expressions with slower reasoning about intentions and beliefs. When people interact smoothly, their neural rhythms in this region align; when their timescales mismatch, misunderstandings follow. Differences in this timing structure also map onto social difficulties seen in clinical conditions, suggesting a biological axis for social skill.
Thinking of social cognition as coordinated timing changes how we study and support human potential. If timing is the lever, interventions could aim to resynchronize rhythms rather than only teach social rules. Follow the full review to see how this timing framework could reshape research, therapies, and inclusive practices by linking lab measures of neural tempo to everyday social success.
Social interactions require integrating information across multiple timescales, yet the underlying mechanisms remain unclear. We review evidence suggesting that intrinsic neural timescales (INTs) may be a key mechanism enabling this integration, with the right temporoparietal junction (rTPJ) serving as a critical hub during social interactions. INTs form a cortical hierarchy for multiscale temporal processing, and differences in this hierarchy are linked to social impairments across neuropsychiatric conditions. The rTPJ dynamically integrates fast mirroring and slow mentalizing processes; interbrain synchrony there predicts success in social interactions, while mismatched timescales between individuals cause communication breakdowns. We propose that this INT and rTPJ framework unifies dual-process theories within a single neurophysiological mechanism, providing a novel, testable account of social interactions and their impairments.
