    A Systematic Investigation of Gesture Kinematics in Evolving Manual Languages in the Lab
    with Mark Dingemanse, Yasamin Motamedi, and Aslı Özyürek
    Cognitive Science 45 (7). 2021.
    Silent gestures consist of complex multi‐articulatory movements but are now primarily studied through categorical coding of the referential gesture content. The relation of categorical linguistic content with continuous kinematics is therefore poorly understood. Here, we reanalyzed the video data from a gestural evolution experiment (Motamedi, Schouwstra, Smith, Culbertson, & Kirby, 2019), which showed increases in the systematicity of gesture content over time. We applied computer vision techni…Read more

    Learning From Gesture and Action: An Investigation of Memory for Where Objects Went and How They Got There
    with Autumn B. Hostetter and Elizabeth M. Wakefield
    Cognitive Science 44 (9). 2020.
    Speakers often use gesture to demonstrate how to perform actions—for example, they might show how to open the top of a jar by making a twisting motion above the jar. Yet it is unclear whether listeners learn as much from seeing such gestures as they learn from seeing actions that physically change the position of objects (i.e., actually opening the jar). Here, we examined participants' implicit and explicit understanding about a series of movements that demonstrated how to move a set of objects.…Read more
