My research interests span a number of fields in Experimental Psychology and Cognitive Science, including attention, skill acquisition and memory. In all of these domains I have focused on understanding something that humans do frequently every day, making rapid choices. With Scott Brown I have proposed and applied the Ballistic Accumulator (BA) and Linear Ballistic Accumulator (LBA) models. The LBA has excellent psychometric properties that have lead to it being widely applied across domains ranging from eye movements to higher level decisions about memory and linguistic knowledge. My most recent work has focused on developing even more easily applied models and using them as building blocks to understand difficult decisions (e.g., due to conflicting information), decisions about complex information (e.g., about objects with multiple attributes) and complex decisions (e.g., rating confidence in decisions).
