Internet-Based Data Collection and Analysis in Decision Making

Summer School - September 14-18

The first Konstanz Summer School "Internet-Based Data Collection and Analysis in Decision Making"  was attended by about 40 PhD students, postdocs and faculty. About half of them were from GSDS and its supporting departments and University of Konstanz and half from institutions all over Europe and even as far as New York. Four experts taught students basic and advanced concepts of Internet-based research, Methods of Decision Making Research, Mediation & Moderation & Mediated Moderation analysis, Experimental design, Principles of Visualization in Science, technologies (e.g Apps, HTML5), Optimal design, Theory and model testing, Mixed models, Analysis of Internet data, Avoiding frequently made errors, Practical applications, Social Media, iScience and Big Data as well as discussed ethics and career options and strategies with the participants. In distinctive evening talks, Prof. Charles Judd spoke about "Decision Biases by Police Officers and Judges" and Prof. Michael Birnbaum and Prof. Gary McClelland (both founders of the Society for Judgment and Decision Making, SJDM) gave a historical introduction to "The early days of the SJDM". Main organizer Prof. Ulf-Dietrich Reips and the Director International Office, Nani N. Clow, gave warm welcome notes and introductions to the graduate school, the university and its surroundings. A social program (e.g. historic picture gallery at Konstanz townhall, Mainau, Meersburg) complemented the workshop program and provided ample opportunity to communicate with teachers and other participants in a relaxed atmosphere and deepen one's knowledge or tailor it to one's own research plans.

Michael Birnbaum received his PhD from UCLA in 1972. He taught at University of Illinois, Urbana-Champaign from 1974-1986, where he was head of the Division of Quantitative and Industrial/Organizational Psychology, and promoted to Full Professor in 1982. He came to California State University, Fullerton (CSUF) in 1986 on leave from University of Illinois, and made the position here permanent in 1988. He is a founder and current co-director of the Decision Research Center at CSUF. He was named Outstanding Professor for CSUF in 1991-92. He has published more than 125 scientific articles and three books. In the last decade, he has had five grants from the National Science Foundation and one from the American Psychological Association. He served as president of the Society for Mathematical Psychology, 2002-2003, president of the Society for Judgment and Decision Making, 2008-2009, and president of the Society for Computers in Psychology, 2009-2010.

Charles "Chick" M. Judd is a College Professor of Distinction at University of Colorado, Boulder. He received his PhD in 1976 from Columbia University after getting a B.A. from Yale. He then became Assistant Professor, then Associate Professor at Harvard University. In 1981 he became an Associate Professor at University of Colorado, Boulder, where he was promoted to Professor of Psychology and Neuroscience in 1987 and College Professor of Distinction in 2006. He has been a Visiting Professor in Bristol, Cardiff, Oxford and Stanford, among others. His research focuses on Social cognition and attitudes; Structure, function, and the measurement of attitudes; Judgment, memory, and decision making. Methods of behavioral science research and data analysis: Experimental design and analysis; Evaluation and quasi-experimental designs and analysis; Linear structural models. Among numerous awards, he received the Thomas Ostrom Award for Lifetime Contributions to Social Cognition Research, 2010 and in 2012 the Jacob Cohen Award jointly with Gary McClelland, see below.

Gary McClelland is a Professor of the University of Colorado, Boulder, received his PhD in 1971 from the University of Michigan, and has been a pioneer in the use of interactive web-based graphics to support understanding of methodological concepts in both scientific journal articles and in educational materials (e.g., Irwin & McClelland, 2003; McClelland, 1997, 2000). Gary's two primary research interests are (1) judgment and decision making and (2) statistical methods. He is a founding member of the Society for Judgment and Decision Making and a founding fellow of the Association for Psychological Science. He and Chick Judd in 2012 jointly won the Jacob Cohen Award for Distinguished Contributions to Teaching and Mentoring by the American Psychological Association, Div. 5.

Ulf-Dietrich Reips is a Full Professor at the University of Konstanz. He received his PhD in 1996 from the University of Tübingen. His research focuses on Internet-based research methodologies, the psychology of the Internet, measurement, development, the cognition of causality, personality, privacy, Social Media, crowdsourcing, and Big Data. In 1994, he founded the Web Experimental Psychology Lab, the first laboratory for conducting real experiments on the World Wide Web. Ulf was a founder of the German Society for Online Research, was elected the first non-North American president of the Society for Computers in Psychology and he is the founding editor of the free open access journal International Journal of Internet Science ( Ulf and his team develop and provide free Web tools for researchers, teachers, students, and the public. They received numerous awards for their Web applications (available from the iScience Server at and methodological work serving the research community.
