Book excerpt: This unique sourcebook describes the research methods used to study human brain function and brain-behavior relationships. These range from relatively simple approaches, such as dichotic listening and tachistoscopic presentation, to computerized techniques such as cerebral blood flow measurements. The description of each method covers the underlying theory, variations on the basic paradigm, dependent measures, reliability and validity, and the equipment required. The authors also critically review research with normal and clinical populations. Because of the rapid expansion of the field of human neuropsychology--and accompanying technological advances--this volume will be valued as much by experienced researchers as by newcomers seeking an introduction to the variety of available procedures.
