The effect of cognitive load on decision making with graphically displayed uncertainty information.

An experiment examined the ability of five graphical displays to communicate uncertainty information when end users were under cognitive load (i.e., remembering an eight-digit number).

Decision making for risk management: a comparison of graphical methods for presenting quantitative uncertainty.

Previous research has shown that people err when making decisions aided by probability information. Surprisingly, there has been little exploration into the accuracy of decisions made based on many commonly used probabilistic display methods. Two experiments examined the ability of a comprehensive set of such methods to effectively communicate critical information to a decision maker and influence confidence in decision making.
