Professor Kevin N. Dunbar, Ph.D.

Kevin Dunbar in Bray, Ireland The goal of my research is to understand the way that people think, reason, and solve problems in a variety of contexts ranging from scientists reasoning in their labs, children and adults learning new scientific concepts, and politicians engaged in debate (see the Dunbar Lab web page for detailed descriptions of my research). We analyze reasoning in naturalistic contexts, as well as conducting controlled experiments in the cognitive laboratory in which we investigate analogy, causal reasoning, and deductive reasoning. We are also investigating the ways that the brain is involved in thinking and reasoning using fMRI. By investigating thinking and reasoning in these different contexts we are able to provide new insights into the cognitive and brain-based mechanisms underlying human thinking. In particular, our investigations of scientists reasoning in their labs has enabled us to go beyond the myths of chance discovery, flash of insight, and the lone scientist toiling against the grain. Instead, we find scientists use well defined strategies for analogical reasoning and causal reasoning as well as group reasoning strategies. This research has implications for the way scientists are educated, science is taught, and theories of how scientists think, reason and make discoveries. The findings from this research can also be incorporated into computer programs that can be used to make scientific discoveries. Finally, this research is providing new insights and models of basic cognitive processes involved in analogy, causal reasoning, induction, problem solving, group reasoning, diagrammatic reasoning and deduction.
