Success in joint tasks requires shared understanding and coordination between team members. Some studies suggest that, in motor tasks, various coordination patterns (including alignment and complimentary) can support achieving shared goals (Wallot et al., 2016; Gorman et al., 2017; M. J. Richardson et al., 2015). I aim to continue to narrow down predictors of joint task efficiency. However, beyond motor coordination, it’s unclear how task partners coordinate other aspects of their behavior, including their language user and shared attention. This study is designed to test and further develop existing models of interpersonal coordination. Pairs of participants used maps to either count landmarks that shared some features or to plan a route between two given stations. Their eye movements and their conversations were recorded. In this project, I will focus on evaluating alignment in joint attention, as indicated by participants’ eye fixations. I will do so by visualizing alignment in two ways: (1) generating videos that illustrate the pairs’ eye fixations over the course of a trial, and (2) generating cross-recurrence plots, which illustrate the density of recurrence points during the trial (i.e., when pairs are looking at the same locations). I hypothesize that pairs’ eye fixations align more closely during route planning than landmark counting tasks. This trend should emerge from task-specific requirements for sharing a consistent joint perspective to obtain the correct answer. This project has the potential to shed light on the patterns of coordination (e.g., alignment vs. complementarity) that support language use during collaborative problem-solving.
