Rosnow Radnor, Pennsylvania U.S.A. Ralph L. Rosnow is Bolton Professor Emeritus at Temple University where (with Robert Lana) he founded the Ph.D. program in social psychology and, from 1967-2001, taught undergraduate and graduate courses in research methods and social psychology. He taught these subjects at Boston University as an assistant professor from 1963-1967, at Harvard University as a visiting professor in 1974 and 1988-1989, and was a visiting professor and occasional lecturer at the London School of Economics in 1973. He has done applied consulting work in his specialty area. In research and theory for over 40 years, he has been interested in the question of how people make sense of their experiential world, impose meaning on events, and justify inferences and conclusions. He has explored this question from the perspective of the social psychology of the experiment, contextualism, rumor and gossip, attitude formation, social cognition, and interpersonal acumen. Currently, he is most interested in focused data analysis (contrasts) and effect size estimation. For over 43 years, he and Robert Rosenthal have collaborated on books, articles, and chapters on research methods and data analysis. Ralph and Mimi Rosnow have collaborated on a popular writing manual for psychology students, now in its eighth edition. Rosnow's B.Sc is from the University of Maryland, M.A. from George Washington University, and Ph.D. in psychology from American University in Washington, DC. He has served on editorial boards of journals and encyclopedias and (with Robert Lana) was General Editor of Oxford University Press's Reconstruction of Society Series. He has been a Fellow of AAAS and APA since 1970 and a Charter Fellow of APS since 1988. He and his wife, Mimi, reside in Radnor, Pennsylvania. Books: Artifacts in behavioral research (2009).
