Winston Sieck is president and principal scientist of Global Cognition, a cognitive science research organization located in Yellow Springs, OH. He investigates the strategies people use to learn, think, and make decisions, including how these strategies differ across cultures and levels of expertise.
One thread of his research seeks to understand people’s certainty in their beliefs and decisions, including the effects of various memory and reasoning strategies on perceived and actual cognitive performance. An extension of this line of work addresses certainty and ideological extremism.
Another research thread involves ways in which fundamental styles of thinking and beliefs about what constitutes “good” thinking differ across cultures, as well as how such differences influence multicultural collaborations and other intercultural interactions.
A third direction of Dr. Sieck’s research examines the cognitive strategy components of cross-cultural competence, the ability to adapt easily and function effectively in new cultures.
Winston Sieck has published extensively on these issues in a variety of scientific outlets, and has served as principal investigator on projects funded by several government agencies to study these and related issues.
Dr. Sieck received a Ph.D. in cognitive psychology from the University of Michigan in 2000, and M.A. in statistics from the same university in 1995. He taught statistics and served as a research fellow at the University of Michigan (2000-2001), and then worked as a post-doctoral researcher in quantitative psychology at Ohio State University (2001-2003). Sieck then joined Klein Associates, a small firm specializing in cognitive-field research and naturalistic decision making, serving there for several years before striking out to found Global Cognition in 2011.
