Turn-taking structure and scoring procedure of the Action Communication Test (ACT; from top to bottom). Each ACT subscale involves standardized questions (“What do you see?” or “What do you want?”), target utterances and, if necessary, verbal or gestural signs of agreement. The subscale ACT Requests also encourages the use of formulaic expressions (e.g., “Here you are,” “Thank you” and “You're welcome”; cf. Stahl and Van Lancker Sidtis, 2015).
