Abstract

Humans use visual information to safely guide locomotion to avoid collisions with objects or other people within cluttered environments. The purpose of the current study was to examine head-on mutual avoidance behaviours of two young adults when approaching an aperture from opposite sides. It was hypothesized that when two young adults are on a collision course, both pedestrians would accurately perceive the difference in arrival time between one another to predict and maintain passing order through an aperture. Nineteen young adults (

years, 9 males and 10 females) participated in the study and interacted with a female research assistant (RA) (22 years, 157.5 cm). Starting at one of two locations on opposite sides of a 10 m pathway, the participant and the RA were instructed to approach one another, and mutually decide who would pass first through an aperture located halfway (5 m) along the path. Kinematic trunk data was collected from both the participant and the RA using the Optotrak motion analysis system. The results revealed that the walkers were able to accurately perceive and maintain the predicted order of crossing (i.e., predicted order matched their observed crossing order) on 90.9 % of the trials. This finding indicate that individuals are in-tune to the visual information necessary in determining and maintaining crossing order, such that the walker passing second (P2) slowed down and deviated from the path to allow the other walker (P1) to pass through the doorway first. Additionally, it was revealed that individuals distribute their gaze fixations equally between the aperture and the approaching person prior to crossing the aperture. The results suggest that when two young adults are approaching a doorway from opposite sides, they may rely on the coupling of two optical expansion rates, or tau-coupling, to determine crossing order as indicated by the low number of inversions. While gaze behaviours are coupled with locomotion to maintaining path trajectory and determining crossing order.

期刊介绍： Human Movement Science provides a medium for publishing disciplinary and multidisciplinary studies on human movement. It brings together psychological, biomechanical and neurophysiological research on the control, organization and learning of human movement, including the perceptual support of movement. The overarching goal of the journal is to publish articles that help advance theoretical understanding of the control and organization of human movement, as well as changes therein as a function of development, learning and rehabilitation. The nature of the research reported may vary from fundamental theoretical or empirical studies to more applied studies in the fields of, for example, sport, dance and rehabilitation with the proviso that all studies have a distinct theoretical bearing. Also, reviews and meta-studies advancing the understanding of human movement are welcome. These aims and scope imply that purely descriptive studies are not acceptable, while methodological articles are only acceptable if the methodology in question opens up new vistas in understanding the control and organization of human movement. The same holds for articles on exercise physiology, which in general are not supported, unless they speak to the control and organization of human movement. In general, it is required that the theoretical message of articles published in Human Movement Science is, to a certain extent, innovative and not dismissible as just "more of the same."
