This book includes seven original studies based on the use of modern neuroimaging techniques, primarily positron emission tomography (PET) and functional magnetic resonance imaging (fMRI).
These techniques are used in the context of a variety of cognitive tasks involving memory, problem solving, and other processes. Unlike most research in psychology, much of the work reported
here explicitly addresses individual differences, which must be considered carefully in order to provide comprehensive accounts of the results of imagery experiments. Although these
investigations were planned and carried out independently, we find a remarkable convergence among them. And this may be the surest sign that the field is indeed moving forward.
