Parents often make health decisions for their children. Visuals have been shown to facilitate decision-making. In this study, I investigated which visual (i.e., icon arrays, number lines, or Arabic numerals) led parents to make the most mathematically-accurate response about the risk of a drug's side effect. Theories from cognitive and social psychology predicted that number lines would be the most helpful. Participants (n = 86, Mage= 38.45, 63.5% female), who were the parent to at least one child, were randomly assigned to view one of the three visual types that were shown between-subjects. Results from the study indicated that icon arrays that visualized large-component fractions (e.g., 108/648) led parents to make the least accurate estimates of side effect risks. For all visuals, participants were more accurate when they estimated small-component (e.g., 1/6) as compared to large-component risks. A practical implication of this research is that small components are ideal when presenting health information.
