“…Possible solutions might include color coding or other visual design features of questions that give meaning to scale points (e.g., "green" for positive or "red" for negative, "thumps up" for agreement and "thumps down" for disagreement) and provide clues on how scale points relate to each other (e.g., by tuning down color by 50%). Research in this area is budding (Stange et al, 2018;Toepoel & Dillman, 2010;Toepoel & Funke, 2018;Toepoel et al, 2019;Tourangeau et al, 2007), although recent studies on the use of smiley faces were not encouraging in terms of data quality and ease of cognitive response processing (Cernat & Liu, 2019;Gummer et al, 2020). Unless convincing progress is made to make rating scales more compact and less screen size space consuming, for now, we recommend complying with the classical advice on using fully labeled rating scales with verbal labels (e.g., Krosnick & Fabrigar, 1997).…”
