| Heuristics | In this study, the influence of verbal, numerical and visual language is tested on a five point scale. In August 2008, a questionnaire was administered to the LISS panel consisting of five questions measured on a five point scale. In September 2008, there was a follow-up survey with different visual heuristics. The aim of the surveys was to find out if the use of numbers and verbal labels reduces the effect of visual language. |
| Heuristics > Part 1 | In August 2008, a questionnaire was administered to the LISS panel consisting of five questions measured on a five point scale. There were 18 different groups, in which three visual heuristics were tested: ‘middle means typical’, ‘left and top means first’, and ‘near means related’. For each heuristic, verbal labels (polar point vs fully labeled), numbers (added or not) and visual language such as color was varied. The aim of the survey was to find out if the use of numbers and verbal labels reduces the effect of visual language. In September 2008, there was a follow-up survey with different visual heuristics (Heuristics II ). |
| Heuristics > Part 2 | In September 2008, a questionnaire was administered to the LISS panel consisting of five questions measured on a five point scale. There were 16 different groups, in which two visual heuristics were tested: ‘up means good’, and ‘like means close’. For each heuristic, verbal labels (polar point vs fully labeled), numbers (added or not) and visual language such as color was varied. The aim of the survey was to find out if the use of numbers and verbal labels reduces the effect of visual language. In August 2008, a similar questionnaire was conducted in the LISS panel testing different visual heuristics (Heuristics I ). |
