This core textbook introduces psychology students to research methods. The author’s principal goal is to present methods in a way that will lend coherence to the material. He does this by providing a meaningful framework based around Campbell and Stanley’s "threats to validity" and by organizing the book around the phases of the research process. In addition, in his approach and via boxed features, the author encourages and models a process of critical thinking for students.
