Methodological, statistical, conceptual, and related topics and issues in the practice and understanding of research with human participants are broad, long-time interests. Beyond that, my students and I have explored variables influencing and factors moderating persuasion and opinion change, the formation of impressions and attitudes, interpersonal acumen (reading and misreading people's actions and intentions), the circumstances and characteristics of rumor and gossip, and some aspects of other constructs illustrative of the sociopsychological context of our understanding of human nature and the processual nature of behavior.

For over 50 years, I have collaborated with my old friend and colleague, Robert Rosenthal, on studies, books, articles, and chapters in the area of research methodology, data analysis, and related topics. Openly available here are scanned copies of full texts of two books for which we now have the rights: (1) the 2008 3rd edition of Essentials of Behavioral Research: Methods and Data Analysis and (2) People Studying People: Artifacts and Ethics in Behavioral Research. You are welcome to freely view and download them for educational purposes, research, or any other noncommercial use. Simply click on the FILES tab at the top of this page, choose the highlighted title of either book, and click on View/Download. The books are also available in Harvard University's DASH repository; click the PUBLICATIONS tab at the top of this page, then click on the title Essentials of Behavioral Research or the title People Studying People, and once directed to the book's site, choose View/Open.

Full-text scanned copies of three additional books (for which my coauthors and I now have the rights) are also openly available here by clicking on the FILES tab at the top of this page, then on a highlighted title of interest, and then choosing View/Download. The books are (3) Writing Papers in Psychology (9th edition, coauthored with Mimi Rosnow; this is a student manual with tips, guidelines, and illustrative examples of proposals, research papers, literature reviews, poster presentations, and concise handout reports); (4) Paradigms in Transition: The Methodology of Social Inquiry; and (5) Rumor and Gossip: The Social Psychology of Hearsay (coauthored with Gary Alan Fine; this is an older book, although it may stimulate some enterprising students to want to learn more about current research and insights internationally).
