Ralph L. Rosnow’s research while affiliated with Temple University and other places

Research today demands the application of sophisticated and powerful research tools. Fulfilling this need, this two-volume text provides the tool box to deliver the valid and generalizable answers to today's complex research questions. The Oxford Handbook of Quantitative Methods in Psychology aims to be a source for learning and reviewing current best-practices in quantitative methods as practiced in the social, behavioral, and educational sciences. Comprising two volumes, this text covers a wealth of topics related to quantitative research methods. It begins with essential philosophical and ethical issues related to science and quantitative research. It then addresses core measurement topics before delving into the design of studies. Principal issues related to modern estimation and mathematical modeling are also detailed. Topics in the book then segway into the realm of statistical inference and modeling with articles dedicated to classical approaches as well as modern latent variable approaches. Numerous articles associated with longitudinal data and more specialized techniques round out this broad selection of topics.

Reports an error in "Effect sizes for experimenting psychologists" by Ralph L. Rosnow and Robert Rosenthal (Canadian Journal of Experimental Psychology/Revue canadienne de psychologie expérimentale, 2003[Sep], Vol 57[3], 221-237). A portion of the note to Table 1 was incorrect. The second sentence of the note should read as follows: Fisher’s ʐr is the log transformation of r, that is, ½ loge [(1 + r)/(1 - r)]. (The following abstract of the original article appeared in record 2003-08374-009.) [Correction Notice: An erratum for this article was reported in Vol 63(1) of Canadian Journal of Experimental Psychology/Revue canadienne de psychologie expérimentale (see record 2009-03064-004). Correction for Note in TABLE 1 (on page 222): The second sentence should read as follows: Fisher’s zr is the log transformation of r, that is, 1⁄2 loge[(1 + r)/(1 − r)].] This article describes three families of effect size estimators and their use in situations of general and specific interest to experimenting psychologists. The situations discussed include both between- and within-group (repeated measures) designs. Also described is the counternull statistic, which is useful in preventing common errors of interpretation in null hypothesis significance testing. The emphasis is on correlation (r-type) effect size indicators, but a wide variety of difference-type and ratio-type effect size estimators are also described.

This book is really three-books-in-one, dealing with the topic of artifacts in behavioral research. It is about the problems of experimenter effects which have not been solved. Experimenters still differ in the ways in which they see, interpret, and manipulate their data. Experimenters still obtain different responses from research participants (human or infrahuman) as a function of experimenters' states and traits of biosocial, psychosocial, and situational origins. Experimenters' expectations still serve too often as self-fulfilling prophecies, a problem that biomedical researchers have acknowledged and guarded against better than have behavioral researchers; e.g., many biomedical studies would be considered of unpublishable quality had their experimenters not been blind to experimental condition. Problems of participant or subject effects have also not been solved. Researchers usually still draw research samples from a population of volunteers that differ along many dimensions from those not finding their way into our research. Research participants are still often suspicious of experimenters' intent, try to figure out what experimenters are after, and are concerned about what the experimenter thinks of them. That portion of the complexity of human behavior that can be attributed to the social nature of behavioral research can be conceptualized as a set of artifacts to be isolated, measured, considered, and, sometimes, eliminated. This book examines the methodological and substantive implications of sources of artifacts in behavioral research and strategies for improving this situation.
