- Abstract
Numeracy is the ability to understand, manipulate, and make sense of numerical information. It is crucial for everyday decision making that involves dealing with numbers. In this study, we tested whether we can help people make better choices in monetary lotteries by communicating numerical values (i.e., payoffs and probabilities) using visual aids. We also checked whether presenting this information in a visual form reduces affect negativity. Participants ( N = 210) made choices in 10 monetary lotteries accompanied with visual aids (experimental condition) or without visual aids (control condition). After the lottery task, participants completed questionnaires measuring experienced emotions and numerical skills. Despite finding no hypothesized effect of visual aids on performance in a lottery task, the exploratory analysis revealed the interaction effect. In a visual aid condition, participants who were relatively less educated scored significantly higher in a lottery task in comparison to those in the control condition. Additionally, participants in the visual aid condition reported significantly lower intensity of negative emotions after the lottery task than those in the control condition. We discuss possible causes and mechanisms that can explain the results we obtained. We argue that visual aids are a promising tool for future learning, and their friendly format can positively influence people's reactions to decisions involving numerical information. However, we also point out the necessity for further research and exploration of the role of different designs of visual aids and individual differences.
