The focus of most of my work is on how people make sense of their experiential world and justify inferences, generalizations, and actions. I have studied and written about aspects of this question from the perspective of volunteer subject bias and other artifacts in behavioral research; attitude and impression formation; the psychology of rumor and gossip; interpersonal acumen, synthetic benevolence, and synthetic malevolence; contextualism and issues in ethics; and the analysis and interpretation of research data. For many years I have had the pleasure of coauthoring a writing manual for psychology students (now in its 9th edition) with my wife, Mimi, and collaborating on books, articles, and empirical studies on research methods and data analytic procedures with my old friend and colleague, Robert Rosenthal. Since retiring from Temple University at the end of 2001, I have been mainly interested in a range of issues related to research methods and data analysis, with particular emphasis on k > 2 contrasts and associated effect size indices.
