2.1.1. Participants

Experiment 1 was conducted at the University of Edinburgh and recruited participants from the university's Careers Hub website. Forty participants (aged 18 to 27, median age = 20; 13 male) took part in a study that required them to produce and interpret gestures for a set of video scenes that depicted objects being used either in a scenario that was either typical or atypical for the object. Participants were paid GBP 7 to take part in the experiment. All participants were self-reported to be right-handed "native" English speakers, with no knowledge of any sign language. Participants took part in the experiment concurrently with another participant, who acted as their communication partner in stage 2 of the task (see Section 2.1.3), giving a total of 20 pairs. Data from 5 pairs were not included in the analyses due to technical errors in video recording.
