How Do Participants Deal with Questions if Asked to Rate Visual Dimensions of an Object?

Research Question: How do participants behave when asked to rate objects’ visual dimensions? Approach: Qualitative Data Analysis Method: 90 participants were asked to rate 11 objects located along a route of 1.1 km length and asked to explain their rating behaviour using a think-aloud protocol. Results: If asked to rate several objects, participants tend to stop reading the questions as a whole. Moreover, when judging objects on visual dimensions they make inconsistent use of local neighbourhoods.
