the United States. Upon arrival in court he or she is beset by a complex system of rules and procedures that are well rehearsed and well understood by the professionals who work in those settings, but complicated and obtuse to the newcomer. In some jurisdictions, the complexity is amplifi ed by the jury selection process. In Canada, for example, two lay "triers" selected from the pool of potential jurors determine whether their fellow jurors can be impartial. In the US, the prosecutor and defense attorneys dismiss potentially biased jurors based either on readily apparent juror prejudices or on attorneys' intuitions about prospective jurors' inclinations. The stated purpose of jury selection in these jurisdictions is to assure the court that those jurors who remain are impartial. But for the prospective juror the questioning process involves a number of complicated cognitive tasks, including reconstruction of the past, forecasting of the future, and inferential reasoning.In any jury trial, empanelled members must sift through confl icting arguments and evidence presentations and a series of exhaustive jury instructions that frequently involve concepts and language unfamiliar to most laypeople. In England, Australia, and Canada, jurors hear summations of the evidence by the judge that may differ in signifi cant ways from attorneys' arguments. Then, during their deliberations, jurors are asked to recall vast amounts of trial evidence, expected to understand and apply their instructions, and ultimately, to decide on an "appropriate" verdict.These procedures beg the question, how do jurors decide on an "appropriate" verdict? How willing, able, and motivated are they to process the large volume of trial evidence, some of it contradictory in nature? How do they assess and combine disparate sources of information? By what process do they evaluate and use the trial evidence in reaching their decisions? How do their prior experiences and preconceptions regarding the judicial Handbook of Applied Cognition: Second Edition. Edited by Francis Durso.
