This textbook for students of psychology and related disciplines introduces methods for behavioral research. Cherulnik's approach builds upon Campbell and Stanley's 1963 monograph, which considered research methods in relation to their vulnerability to threats to internal and external validity. The text is organized around the chronological steps of the research process, from formulating a hypothesis through collecting and analyzing data and reporting the results. Cherulnik (current affiliation not cited) has taught psychology for more than 30 years at a number of colleges and universities. Annotation c. Book News, Inc., Portland, OR (booknews.com)
