      abstract = {This study reanalyzed motion capture data from 13 native  American Sign Language (ASL) signers and 32 hearing English  speakers, who were asked to physically imitate and then  describe the trajectory of a three-dimensional version of  the Müller-Lyer illusion (Brown et al., 2021). Building on  the previous findings that all participants were less  affected by the visual illusion when actually interacting  with the object or gesturing/signing while describing it  than when estimating the size of the object, this study  examines specific kinematic features of their gesture,  focusing on smoothness, accuracy, velocity, and rhythmicity  using dynamic time warping and other quantitative methods.  This analysis demonstrated that signers have smoother  movements during gestures about trajectory than English  speakers (but not during instrumental action), have faster  hand movements overall, have greater general rhythmicity in  their gestures (particularly in description tasks), and are  less accurate in their description of the object’s  trajectory than English speakers. These results suggest  that there are subtle differences in the gestures produced  by signers and speakers, which may indicate their  engagement of different cognitive mechanisms while  producing descriptive gestures. Specifically, this process  seems to be more informed by action in speakers, but more  by language in signers.},
