When such mutual anticipation fails, this may result in collisions or near-collisions. Previous research on mutual anticipation in collision avoidance has highlighted the importance of kinematic information. However, it remains unclear how full-body kinematics support mutual anticipation in truly interactive near-collision avoidance scenarios.\u3000We introduce cross-recurrence quantification analysis (CRQA) as a novel method to quantify the degree of mutual hesitation (i.e., spatiotemporal overlap between walkers) in near-collision avoidance. Additionally, we examined which pre-avoidance, inter-participant kinematic relationships predict the degree of mutual hesitation. Forty-five dyads (i.e., 90 participants) walked toward each other and aimed at avoiding collision in two differently sized avoidance zones (20\u00a0cm, 80\u00a0cm). Results revealed that the mean Recurrence Rate in mutual hesitation trials was 37.97 (\u00b1\u200923.2) and 41.95 (\u00b1\u200925.5) in the respective collision avoidance zones. Statistical Parametric Mapping showed that inter-participant head-angle differences diverged earlier than the shoulder or pelvis in non-mutual hesitation trials. Smaller head-angle differences 0.3\u20130.2s (20\u00a0cm) and 0.2\u20130.1s (80\u00a0cm) before avoidance onset predicted a higher degree of mutual hesitation. We conclude that failures in inferring avoidance direction from head kinematics may be linked to mutual anticipation errors that result in mutual hesitation.<\/jats:p>","DOI":"10.1038\/s41598-026-59801-3","type":"journal-article","created":{"date-parts":[[2026,7,7]],"date-time":"2026-07-07T20:35:47Z","timestamp":1783456547000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Quantifying mutual hesitation and identifying kinematic predictors in near-collision avoidance in walking"],"prefix":"10.1038","volume":"16","author":[{"given":"Kazuyuki","family":"Sato","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johannes","family":"Keck","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rouwen","family":"Ca\u00f1al-Bruland","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,7,7]]},"reference":[{"key":"59801_CR1","doi-asserted-by":"publisher","first-page":"1013","DOI":"10.3389\/fpsyg.2015.01013","volume":"6","author":"M Honma","year":"2015","unstructured":"Honma, M., Koyama, S. & Kawamura, M.
