Abstract The inattentive eye often will not notice it but synchronization among human walking partners is quite common. In this first investigation of this phenomenon we studied its frequency and the mechanisms that contribute to this form of entrainment. Specifically by modifying the available communication links between two walking partners we isolated the feedback mechanisms that enable couples to synchronize their stepping pattern when they walk side-by-side. Although subjects were unaware of the research aims and were not specifically asked to walk in synchrony we observed synchronized walking in almost 50 of the walking trials among couples who do not usually walk together. The strongest in-phase synchrony occurred in the presence of tactile feedback . .
