Participants were asked to answer nine statements on a 9-point Likert scale from 1 (strongly disagree) to 9 (strongly agree). These statements were related to perceptions of FoPLs; in particular ease of understanding (e.g., “this label is easy to understand”, “this label is too long to understand”), label visibility (“This label does not stand out”), appreciation (“I like this label”) and trust (“I trust this label”).
