Research interests

Deductive reasoning - especially the study of biases, linguistic and pragmatic factors.

Rationality and reasoning. Dual process theory.

Decision making and judgement - heuristics and biases in probability judgement; judgement analysis; medical decision making.

Since 2000, I have been awarded four project grants from ESRC, as well as a personal research fellowship, with a total value of over £400,000. The project grants are for research on multicue judgement, judgement under uncertainty and for study of reasoning with and comprehension of conditional statements. I have developed a new theory of conditionals (Evans & Over, If, Oxford University Press, in press) which is the major focus of recent grant awards.

From November 2005 to April 2008 I am on fellowship leave funded by the ESRC to develop the dual system theory of cognition.

Publication highlights in the past five years include a major review of the deductive reasoning field published in Psychological Bulletin, two experimental papers in Journal of Experimental Psychology: Learning, Memory and Cognition; two papers in Memory & Cognition and a review of dual process theory published in Trends in Cognitive Sciences.  I have also developed a new version of my heuristic-analytic theory of reasoning which has recently been published Psychonomic Bulletin and Review and forms the basis for a new book on Hypothetical Thinking, in press with Psychology Press.
