Richard E. Petty [Faculty]

Rich received his MA and PhD degrees from Ohio State University where he currently is Distinguished University Professor of psychology.  Much of his current work (and that of the students and colleagues with whom he collaborates) focuses broadly on the situational and individual difference factors responsible for changes in beliefs, attitudes, and behaviors.  Topics of special current interest include: understanding the role of meta-cognitive (e.g., confidence/certainty) as well as implicit (automatic or unconscious) factors in persuasion, resistance to change, and advocacy; the effect of racial and ethnic prejudice and specific emotions on social judgment and behavior; and investigating how people correct their evaluations for various factors they think may have biased their judgments.  He has received career contribution awards from SESP, SPSP, SCP, and PMIG.  His prior service includes editing PSPB and serving as President of SPSP, FPSP, and MPA.  His work has resulted in 8 books and over 350 journal articles and chapters.

Duane T. Wegener [Faculty]

Duane received his MA and PhD degrees from Ohio State University.  After serving as Assistant Professor of psychology at Yale and Associate Professor and Full Professor at Purdue University, he joined OSU in 2010 where he is currently Arts and Sciences Distinguished Professor of psychology.  His research focuses on attitudes and bias correction.  Current topics include influences on the amount and nature of information processing, antecedents of various aspects of attitude strength, meta-cognitive influences on use of attitudes in judgment and behavior, and antecedents and consequences of perceptions of persuasive source characteristics.  His research extends theories of attitudes and bais correction across domains such as stereotpying, misinformation effects, impression formation, and judgment and decision-making.  His recognitions include the APA Early Career Award for Distinguished Scientific Contributions to social psychology (2001) and serving as editor of PSPB (2013-2016). His research has resulted in 1 book and over 100 journal articles and book chapters.

Pablo Briñol [Research Associate]

Pablo received his MA and PhD degrees from the Universidad Autónoma de Madrid where he currently serves as Associate Professor.  After a postdoc with Richard Petty, he continues as a regular visiting scholar at Ohio State. His primary research interest focuses on the study of the psychological mechanisms underlying attitudes and persuasion with an emphasis on metacognitive processes and measures of change. In 2017 he received the Kurt Lewin Medal from the European Association of Social Psychology as a leading mid-career researcher in social psychology. His research has appeared in the field's top journals and includes more than 100 publications.

Daniel Rovenpor [Postdoctoral Fellow; Advisor:  Richard Petty]

Daniel completed his Ph.D. in social psychology in 2016 at the University of Massachusetts-Amherst and is currently a postdoctoral fellow at Ohio State.  His research examines how emotion influences attitudes and information processing, how motivational factors shape emotional preferences, and how basic emotional processes underlie broader socio-political issues such as intergroup conflict and support for social justice.  He is currently examining the context-dependent effects of emotions on attitudes, the mechanisms underlying the "valence framing" effect, and how the certainty with which persuasive messages are delivered influences attitudes at different levels of cognitive elaboration.

Geoff Durso [Advisor:  Richard Petty]

Geoff completed a BS in marketing and a BS in psychology at Indiana University.  He received his MA in social psychology at Ohio State in 2013 and is currently a PhD candidate.  His broader research interests focus on the psychological process of evaluation - what makes something good, bad, or both.  He and his colleagues examine evaluative processes in three interrelated areas: (1) How people perceive and manage their conflicting negative and positive information (ambivalence), (2) how people respond to confirmations and violations of their evaluative expectations, and (3) how, when, and why people exhibit differential sensitivity to both positive and negative information.  Portions of his work (in collaboration with Baldwin Way) employ theories and findings from social neuroscience to examine common factors that underlie evaluative processes and emotional reactivity. His research has appeared in Psychological Science, the Journal of Experimental Social Psychology, Personality and Social Psychology Bulletin, the Review of General Psychology, and Social Psychological and Personality Science.

Luke Hinsenkamp [Advisor:  Richard Petty]

Luke received his BS in psychology from the University of Wisconsin-Madison in 2009.  He is now a Ph.D. candidate in the social psychology program working on projects investigating knowledge certainty and attitude ambiguity.  He is also interested in applying the lab's persuasion findings to information-delivery in situations in which pathways to objective processing are short-circuited by cognitive or affective biases, in hopes of reducing political and ideological tensions.  A third line of interest is in the perception of (and actual differences in) non-religious individuals versus others.

Jaroth Lanzalotta [Advisor:  Richard Petty]

Jaroth received his BA in psychology from Reed College in 2017. He is currently a first year student in the social psychology Ph.D. program. Jaroth's research interests lie broadly in the domain of social influence, specifically regarding persuasion, compliance, and conformity, with related interests in group dynamics regarding intergroup discrimination and biases.  He is especially interested in how and why people resist such influence.  Jaroth can be reached at

Nick O'Dell [Advisor:  Duane Wegener]

Nick received his BA (2010) and MA (2013) in psychology from California State University-Fullerton.  He is a Ph.D. candidate in the Decision Psychology graduate program.  His primary research focuses on how individuals' perceptions of their own decision making ability in certain contexts influence choice satisfaction and confidence/certainty.  Additional areas of interest include meta-cognitive beliefs and dissociations of subjective vs. objective ability (intelligence, confidence, need for cognition), as well as human fallacies and misattributions.  Nick can be reached at

Kathleen Patton [Advisor:  Duane Wegener]

Kathleen completed her BS in Psychology at John Carroll University in 2013 and her MA at Ohio State University in 2015.  Currently a Ph.D. candidate in the social psychology program, her research interests concern the motivated use of attitudes to reduce conflicted feelings.  One line of research investigates the role of ambivalence on interpersonal attraction.  A second line of interest asks when and why people may change their attitudes following a decision.  In addition, Kathleen has been exploring the outcomes of major political events on invested attitude holders.

Aviva Philipp-Muller [Advisor:  Duane Wegener]

Aviva received her B.Sc. from the University of Toronto in 2016.  She is interested in the consequences of moral conviction and how feeling that an issue is morally charged might affect one's attitude.  Along with Profs. Wegener and Petty, she is currently looking at how possessing strong moral conviction about an issue affects behavioral outcomes as well as how moral conviction affects individuals as recipients of persuasive messaging.  Her other research intersts include attachment in relationships and environmental sustainability messaging.

Joe Siev [Advisor:  Richard Petty]

Joe completed a BA in history from the University of Maryland-College Park in 2009 and following post-baccalaureate work in psychology at CUNY-Brookly College, began OSU's social psychology PhD program in August, 2017.  His research interests center on attitude extremity and polarization, including the roles of ideology and group membership.  Currently, Joe is studying the process by which individuals fuse with groups and enact their (sometimes extreme) ideologies, and exploring a potential avenue to attitude depolarization.  He can be reached at

Mark Susmann [Advisor:  Duane Wegener]

Mark received his BA in psychology from SUNY-Geneseo in 2015 and he is currently a second year student in the social psychology Ph.D. program.  Mark's research interests broadly lie in the examination of how attitudes influence one's perceptions of information and why people rely on certain peices of information about others. Recently, Mark has been examining how attitudes and perceptions of the source can affect people's reaction to numeric anchors.  Additionally, Mark has been investigating how and why people continue to rely on retracted misinformation and the consequences this continued reliance may have.

Jake Teeny [Advisor:  Richard Petty]

Jake received a BS in psychology and philosophy from Santa Clara University in 2012, and his MA in social psychology from OSU in 2015.  Currently a Ph.D. candidate in the field, Jake researches attitudes and persuasion, specifically, when and why people try to convince you of their beliefs (i.e., the antecedents of advocacy).  Additionally, he works with the marketing department at OSU to study when people engage in word of mouth.  To learn more about Jake's other research interests and projects (as well as read some of his short stories), his website can be found at

Laura Wallace [Advisor: Duane Wegener]

Laura received her BA in Organizational Communication from Xavier University in 2012 and her MA from Ohio State in 2015.  She is currently a Ph.D. candidate in the social psychology program.  Her research primarily asks two questions:  (1) What factors make an advocate more or less effective, and (2) What makes people work for social change.  Recently, Laura has been exploring when people will perceive an advocate as biased and what consequences that might have for persuasion attempts.  Laura has also been exploring how people manage the choice to defend or change their social systems when they learn that the system is flawed.

Nancy Xu [Advisor: Richard Petty]

Nancy received her BA in psychology from the University of Virginia in 2015.  She is now a third year graduate student in the social psychology Ph.D. program.  Broadly, speaking, she is interested in thought confidence, self-validation, and attitude change.  Currently, she is working on projects investigating the differential predictive validity of the two need to evaluate subscales (learning & expressing).  Additional areas of interest include power relationships as well as resistance to attitudinal changes in cross-cultural contexts.  Nancy can be reached at
