Rosnow Radnor, Pennsylvania U.S.A. Ralph L. Rosnow has long been interested in how people make sense of their contextual experiences and justify inferences and conclusions. He has explored these questions from several perspectives, starting with experimental research on the adventitious conditioning of primacy and recency effects in attitude formation, continuing in work on extraneous factors (artifacts) that often go unnoticed but can jeopardize the tenability of inferred causal relationships in experiments with human subjects (including work on the volunteer subject with Robert Rosenthal), then in research on rumor and gossip and in work on the cognitive structure of interpersonal acumen. He is also interested in certain philosophical and ethical issues. For a number of years, he and Robert Rosenthal have collaborated on many books and articles about research methods and statistical data analysis. Rosnow is now Thaddeus Bolton Professor, Emeritus, at Temple University, where he taught in the psychology department for 34 years and, with Robert E. Lana, started the doctoral program in social psychology. Rosnow has also taught research methods and social psychology at Boston University and as a visiting professor at Harvard University, and he was a visiting professor and occasional lecturer at London School of Economics (LSE). With his wife, Mimi Rosnow, he has coauthored a popular writing manual for psychology students. He has served on editorial boards of journals and encyclopedias and, with Robert E. Lana, was General Editor of Oxford University Press's Reconstruction of Society Series in the 1970s. He is a Fellow of AAAS, APS, and APA, a recipient of the George A. Miller award, and was recently honored with a Festschrift book edited by Donald A. Hantula (Advances in Social and Organizational Psychology). Books: Artifacts in behavioral research (2009).
