Medical decision-making with tables and graphs: The role of cognition, emotions, and analytic thinking.

The shift from one-way to two-way communication in healthcare decision-making has heightened the need to understand the role of display formats including tables and graphs as decision aids. In this paper, we investigate cognitive and affective influences on decision-making involving display formats. We find that a display format's impact on decision quality is mediated by two distinct components of cognition (verbatim and gist knowledge), and that tables compared to bar graphs improve decision quality. We also find evidence that analytic thinking and lower negative affect can improve decision quality. Implications for marketers, better engaging patients, and encouraging improved decision-making are discussed.
