“…As an example, we may consider couples doing grocery shopping together at the supermarket (see e.g., De Stefani, 2013), students in a peer group choosing their next learning activities (Kämäräinen et al, 2020), and family members together interpreting inkplot images in a psychological test (Siitonen and Wahlberg, 2015). However, empirical research on naturally occurring joint decisionmaking interaction has shown it to be a complex interactional endeavor (Bilmes, 1981;Tysoe, 1984;Boden, 1994;Huisman, 2001;Clifton, 2009;Asmuss and Oshima, 2012;Siitonen and Wahlberg, 2015). It involves the use of multiple resources: syntax, lexical choices, prosody, body postures, material objects, and gaze, in and through which the participants manage their level of participation and the relative distribution of agency during the different phases of the process in contextually appropriate ways (Stivers, 2005;Stevanovic, 2012b;De Stefani, 2013;Stevanovic, 2013a;Kushida and Yamakawa, 2015;Stevanovic, 2015;Stevanovic et al, 2017).…”
