Abstract: Hyperscanning approaches are becoming increasingly common for studying shared neural responses during collaborative or social tasks. Many of the current hyperscanning procedures rely on one of two possible approaches: (1) tightly controlled, highly structured, rigid tasks, or (2) loosely controlled, unstructured, flexible tasks. Both approaches make important and non-trivial tradeoffs regarding internal and ecological validity. Here, we present a novel third approach that balances these tradeoffs. AR Tangram is a mobile-phone based application that uses augmented reality technology to allow pairs of participants to simultaneously complete a naturalistic tangram figure matching task. Tangram matching is a well-validated procedure that belongs to a family of communication tasks that are employed to measure trust, mutual understanding, coordination, shared goals, and partner impression. Importantly, AR Tangram’s use of mobile technology allows for the simultaneous and time-locked recording and automatic annotation of relevant behavioral and linguistic markers that can be used in subsequent analysis. The task is, therefore, suitable for paradigms designed to examine behavioral, linguistic, and neural synchrony among pairs of participants. We will present a demonstration of the hyperscanning paradigm using AR Tangram and the Muse EEG system along with the relevant code and materials for deploying the paradigm in other labs.
