The eleventh edition of methods in behavioral research has benefited greatly from the addition of a new author, Scott C. Bates of Utah State University. The primary focus of the book remains constant. We continue to believe that teaching and learning about research methods is both challenging and great fun, and so we emphasize clear communication of concepts using interesting examples as our highest priority. We have added to and updated our examples, clarified concepts throughout and removed material that was distracting or confusing. We continue to enhance learning by describing important concepts in several contexts throughout the book; research shows that redundancy aids understanding. We also emphasize the need to study behavior using a variety of research approaches. An important change is the addition of illustrative articles in most chapters: students are asked to find and read a specific recent journal article and answer questions that require use of concepts introduced in the chapter.
