With significant new and updated content across dozens of chapters, this second edition presents the most exhaustive treatment available of the techniques psychologists and others have developed to help them pursue a shared understanding of why humans think, feel, and behave the way they do.   The initial chapters in this indispensable three-volume handbook address broad, crosscutting issues faced by researchers: the philosophical, ethical, and societal underpinnings of psychological research. Next, chapters detail the research planning process, describe the range of measurement techniques that psychologists most often use to collect data, consider how to determine the best measurement techniques for a particular purpose, and examine ways to assess the trustworthiness of measures.   Additional chapters cover various aspects of quantitative, qualitative, neuropsychological, and biological research designs, presenting an array of options and their nuanced distinctions. Chapters on techniques for data analysis follow, and important issues in writing up research to share with the community of psychologists are discussed in the handbook’s concluding chapters.   Among the newly written chapters in the second edition, the handbook’s stellar roster of authors cover literature searching, workflow and reproducibility, research funding, neuroimaging, various facets of a wide range of research designs and data analysis methods, and updated information on the publication process, including research data management and sharing, questionable practices in statistical analysis, and ethical issues in manuscript preparation and authorship.

This compelling work brings together leading social psychologists and evaluators to explore the intersection of these two fields and how their theory, practices, and research findings can enhance each other. An ideal professional reference or student text, the book examines how social psychological knowledge can serve as the basis for theory-driven evaluation; facilitate more effective partnerships with stakeholders and policy makers; and help evaluators ask more effective questions about behavior. Also identified are ways in which real-world evaluation findings can identify gaps in social psychological theory and test and improve the validity of social psychological findings; for example, in the areas of cooperation, competition, and intergroup relations. The volume includes a useful glossary of both fields' terms and offers practical suggestions for fostering cross-fertilization in research, graduate training, and employment opportunities. Each tightly edited chapter features an introduction and concluding reflection/discussion questions from the editors.
