Research InterestsI am fortunate to be collaborating with a number of faculty colleagues who are leaders in their fields and two very capable graduate students in Arwen Behrends and Shannon Moore. Most of the research we are conducting is concerned with judgment and decision making.
Some of our work examines the fundamental processes through which decisions are made. One of our current studies investigates how emotions combine with reasoning to determine choice. A study planned for the fall examines the impact of the priming of alternatives on the choice reasoning process.
Another line of research is concerned with applied decision making. David Strayer and I have conducted several studies investigating the causes and consequences of cell phone use while driving. Some of our work has examined the attitudes and beliefs underlying cell phone use behind the wheel and contributing to the support for legislation to restrict this usage of cell phones. Our research has also examined more generally why people multi-task. Interestingly, our findings indicate that the people who multi-task the most tend to be the worst at it. Most recently, we have been investigating the effects of distractions such as cell phones on the self-regulation of driving.
Our longest standing line of research has been concerned with the impact of attitudes on behavior. One current study attempts to show that the role of attitudes in decision making and behavior is much more extensive than current theory postulates. We have also been conducting research with Steve Posavac on consumer attitudes and decision making. Other work examines the relation between attitude functioning, the structural characteristics of attitudes, and behavior. Finally, Bert Uchino and I have been investigating the important role of attitude familiarity in social interactions. Because attitudes are central to behavior, knowing others’ attitudes is crucial for providing support, avoiding conflict, and maintaining close relationships.
