Richard E. Petty [Faculty]

cropped-rep-headshot11.jpgRich 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, specific emotions, and morality 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 being Editor of PSPB and serving as President of SPSP, FPSP, and MPA. His work has resulted in 8 books and over 400 journal articles and chapters.
