Hanlu He @hanluhe.bsky.social · 07/12/2025Acoustic conditions also modulated IPS: low-to-moderate sound pressure levels (SPL) and moderate-to-high signal-to-noise ratios (SNR) enhanced synchrony, while high SPL reduced it to levels characteristic of non-interactive contexts. 120
Hanlu He @hanluhe.bsky.social · 07/12/2025Context matters. Synchrony emerged during close-proximity interactions and when people were exposed to common stimuli, but not during dispersed, non-interactive settings. 120
Hanlu He @hanluhe.bsky.social · 07/12/2025Synchrony was stronger for pairs who already knew each other — even after controlling for being in the same place. 110
Hanlu He @hanluhe.bsky.social · 07/12/2025People’s heart rates synchronized reliably when they were physically close, indicating that shared spatial and contextual exposure was sufficient to produce IPS. 110
Hanlu He @hanluhe.bsky.social · 07/12/2025To address this, we collected continuous heart rate, GPS, and acoustic recordings from 72 participants across three independent multi-day trips to New York City, totaling >1000 hours of multimodal data. 130
Hanlu He @hanluhe.bsky.social · 28/04/2025First time at #SANS2025! Thrilled to hear about all the fascinating work and to present our own from @sinelabdtu.bsky.social @ale-dabr.bsky.social! 0123
