Estimated mean finger complexity for Object-HSs and Handling-HSs in signers and gesturers by Country. Signers in both countries replicated the previous cross-linguistic findings (higher finger complexity for Object-HSs than for Handling-HSs). Gesturers in both countries showed the opposite pattern (higher finger complexity for Handling-HSs than for Object-HSs). The estimated values provided by the model reflect the effects of removing covariates (such as stimulus item and participant) and, in this sense, provide a more accurate picture of the underlying patterns in the dataset than the observed values (which can be found in Appendix A). Because these are estimated values provided by the model, their values can be less than 1, which was the minimum finger complexity value assigned in our system.
