When the answers to all 5 effective- ness tasks were counted, on average, participants who had seen the circle gave 3.24 (SD 1⁄4 1.07) correct answers; participants who had seen the pyra- mid, 2.88 (SD 1⁄4 0.75); and partici- pants who had seen the rainbow, 2.74 (SD 1⁄4 1.06). Results of a 1-way ANOVA suggest that these mean values did not differ significantly (F[2,92]1⁄42.176,P1⁄4.12).Onthe level of the single statements, how- ever, there were some effects (Table 1). However, no format was generally better or worse than the others. Fur- thermore, there was no type of state- ment (composition or belonging to a food group) that was solved better orworsebymeansof1ofthe3 formats.
There were no differences between the 3 formats regarding total number of fixations and total fixation dura- tions (Tables 2 and 3). Thus, overall, all formats seemed to be equally efficient in conveying nutrition information. However, there were significant differences between the formats regarding the fixations’ distribution on the segments of the graph (Table 2); par- ticipants in the circle group paid more attention to the beverages and less to starchy food than participants in the pyramid group. One explana- tion for this finding could be that participants paid relatively more at- tention to the food groups in the center of the graphs (beverages in the circle, starchy food in the pyra-
mid) than to those in the more pe- ripheral areas.
