Variations were introduced into the configuration of the stimuli to discourage the development of stereotypical strategies and encourage extensive examination of the display (see Graph Stimuli and Text sections). None of these manipulations affected the rate of visits. Specifically: (1) whether the bars were grouped by Item or by Attribute, F(1, 20) = 0.77, p = 0.39; Instruction type: F(1, 20) = 1.17, p = 0.29; (2) whether the relative values of the two items on each attribute were consistent or in conflict, F(1, 20) = 0.89, p = 0.36; Instruction type: F(1, 20) = 0.95, p = 0.34; or (3) whether the text was redundant with the graph or introduced new or different information, F(1, 20) = 3.74, p = 0.068; Instruction type: F(1, 20) = 1.47, p = 0.24. In the case of redundancy, there were 0.13 visits/s (SD 0.037), N = 22. For nonredundant text there were 0.14 visits/s (SD 0.035), N = 22.
