2 Activity Report 2015/2016
From the Director
Another year, another milestone.
In 2014, INSEAD’s behavioural lab, as it was then known internally, opened its door to our partners from Sorbonne University (SU) and everything changed. We removed the old plaque on 6 rue Victor Cousin and bolted a new one that read “Centre Multidisciplinaire des Sciences Comportementales Sorbonne Universités-INSEAD” and changed our website to www.inseadsorbonnelab.com. Colleagues from all key members of Sorbonne University—Université Pierre et Marie Curie, Université Paris Sorbonne, the Museum National d’Histoire Naturelle, and the Université de Technologie de Compiègne—joined our board. And then we waited, oscillating between the fear that no-one from SU would find our services useful, negating the substantial investment made by the university, and the fear that we would be unable to cope with a flood of new requests.
Two years later, I am proud to report that both fears were unfounded. Thanks to a textbook marketing 2.0 mix of emailing, off-site presentations, and on-site tours, we quickly recruited our first two teams, one from Paris Sorbonne and one from the Museum. They were rapidly followed by a couple of teams from UPMC who tested their fancy research tools at the lab. And then, in pure S-curve fashion, came the flood! The activity of the lab, as measured by the number of people participating in studies, jumped by 33% in 2014/2015 and then again by 32% in 2015/2016. As I am writing these lines, INSEAD only accounts for 33% of the researchers, 20% of the PhD students, and 42% of the people who participated in studies at the lab.
The collaboration with Sorbonne University did more than increase the activity of the lab. It also significantly broadened its skill set. Thanks to the funding made available by Sorbonne University, and prompted by the enthusiasm of UPMC colleagues, the lab has now acquired an eye-tracker, electroencephalogram recorders, skin conductance recorders, a face reader to measure emotions, and a motion-capture software to measure people’s postures and movements. The lab’s team has
conducted multiple workshops to train colleagues and students with these tools, which are now being adopted by researchers from other institutes.
Last but not least, the lab will launch in 2017-2018 the Sorbonne University INSEAD Distinguished Visiting Chair in Behavioral Sciences. The goal of the visiting chair, which is funded by Sorbonne University, is to attract world-level scholars and to enhance the visibility of the behavioral research conducted at SU. I am delighted that the first chair holder will be Professor Wendy Wood, who is the Provost Professor of Psychology and Business at the University of Southern California and Vice Dean of Research. Her research addresses the ways that habits guide behavior—and why they are so difficult to break. She is a world leading researcher (150+ publications, 20,000+ Google scholar citations), former Associate Editor of Psychological Review, JPSP and President of the Society for Personality and Social Psychology.
In closing, I would like to thank all the colleagues who chose to conduct studies at the lab. We are proud of your continued support. My deep appreciation also goes to the fantastic team of researchers—Huong Ngo, Jean-Yves Mariette, Nicolas Manoharan, Germain Dépetasse, and Sébastien Robin—who, under the supervision of Liselott Pettersson, have made all of these achievements possible.
Pierre Chandon, The L’Oréal Chaired Professor of Marketing – Innovation and Creativity, INSEAD, Director of the INSEAD-Sorbonne University Behavioural Lab
4 Activity Report 2015/2016
“My first experience with the INSEAD-Sorbonne University lab in summer 2015 is the stuff of legend. The experiment had taken us 6 years to nail down, and there we were, July 1st, looking at a lukewarm set of reviews requesting a massive additional control experiment due only 60 days later. My lab did not have the infrastructure to run 100 participants in such short time, nor did my colleagues’ overseas. We turned to INSEAD for help, and within a month and a half we had had our ethical application approved, rebuilt an entire experimental setup involving real-time voice transformations and electrophysiology, and had run N=90 participants, all this in the middle of the French summer vacation. The paper was accepted by PNAS in the first week of October. I can confidently say I had never seen research proceed that fast. “You’ve got me, I’m moving to Paris”, one of my Swedish co-authors wrote in reaction.”

Research input
Research output
The lab is open to researchers from Sorbonne University (of which INSEAD is a founding member) and HEC. We provide the premises, specialised software/hardware, access to a pool of over 5,000 volunteers, and a team of skilled in-house experimenters – basically everything you could wish for to conduct world-class lab experiments with human participants. The researchers choose their topics freely – we do not impose the research agenda. We work on a “first come, first served” basis which enables us to start data collection swiftly. There are no quotas; if an experiment is ready, we collect the data. And we cut no corners.
During the academic year 2015/2016, 11,439 volunteers participated in our lab experiments, the highest number since it opened in 2002.
It is a great source of pride for us to see researchers publish peer-reviewed articles based on data collected at the lab year after year. Since 2002, an impressive 128 articles have been published in peer-reviewed journals such as the Journal of Personality and Social Psychology, Journal of Experimental Psychology: General, and the Journal of Marketing Research. During 2015/2016, researchers using the lab published 17 peer-reviewed articles. Every year, PhD students successfully defend their theses and obtain prestigious placements in research institutions around the world.

6 Activity Report 2015/2016
Visiting Chair in behavioural sciences
Thanks to the funding of Sorbonne University, Professor Wendy Wood from the University of Southern California will be the first holder of the new Sorbonne University INSEAD Distinguished Visiting Chair in Behavioural Sciences. The goal of the visiting chair is to attract world-level visiting scholars in order to promote behavioral research at SU and to enhance the visibility of the behavioral research conducted at SU. We are planning a prestigious event to launch the chair in January 2018, in addition to research seminars and method workshops.
The first chair holder will be Professor Wendy Wood, a world leading researcher (150+ publications, 20,000+ Google scholar citations) who is the Provost Professor of Psychology and Business at the University of Southern California and Vice Dean of Research. Her research addresses the ways that habits guide behavior—and why they are so difficult to break. Wendy Wood was the James B. Duke Professor of Psychology and Neuroscience and Professor of
Marketing. At Duke, Dr. Wood served as Co-Director of the Social Science Research Institute. While Co-Director, she also helped to found the National Consortium of Interdisciplinary Social Science Institutes. Dr. Wood is a Fellow of the American Psychological Association (Division 8), the American Psychological Society, Society for Experimental Social Psychology, and founding member of the Society for Research Synthesis Methodology. She served several terms on the Executive Committee of the Society of Experimental Social Psychology, was previously the Secretary-Treasurer of Society for Personality and Social Psychology, and is now serving a presidential term at Society for Personality and Social Psychology. She is also currently Associate Editor of Behavioral Science and Policy, and in the past has been associate editor of Psychological Review, Journal of Personality and Social Psychology, Personality and Social Psychology Bulletin, and Personality and Social Psychology Review.

The team
INSEAD Institutional Review Board’s (IRB) ethical validation
Partnerships
Our multilingual team has advanced degrees in behavioural sciences and a solid experience of experimental research. We take pride in our work and enjoy collaborating with researchers from all behavioural disciplines. With 91,893 participants since opening in 2002, we have probably conducted more behavioural experiments than any other lab of this kind.
Ethical validation is compulsory to publish research involving human participants in scholarly journals. It is also crucial to guarantee the wellbeing of research participants and to protect researchers and their institutions. The INSEAD Institutional Review Board’s (IRB) provides ethical validation in a streamlined process which takes an average of 3 days when all the information is provided in the original submission.
We are proud that HEC Paris has renewed for the sixth consecutive year its partnership with the lab, giving access to HEC researchers and PhD students to the lab’s infrastructure and services, and providing an additional source of funding for its operation.
8 Activity Report 2015/2016
New research equipment
The lab has recently acquired new high-tech measurement tools to complement traditional self-reported or observational measures. We now have an eye-tracker, electroencephalogram recorders, skin conductance recorders, facial recognition software to measure emotions, and motion-capture software to measure posture and movement. The lab team has conducted multiple workshops to train researchers and students in the use of these tools.

Faculty & post-doctoral fellows
PhD students
We believe researchers should be free to concentrate on what they do best – designing, analysing and writing up studies – and let us take care of the organisational nuts and bolts. When researchers choose to do that, they entrust us with their professional reputation. We know this. That’s why we never settle for anything less than total scientific integrity.
During the 2015/16 academic year, 33 faculty members & post-doctoral fellows conducted experiments at the lab. This is the highest number ever.
The lab is not only a research tool; it is also a learning tool where PhD students discover the fine arts of behavioural research with human participants under the guidance of their advisor and our experienced lab team. With our equipment and expertise, PhD students can collect more data in less time, thus enhancing their chances on the job market. During the 2015/16 academic year, 15 PhD students conducted experiments at the lab.

“My research interest lies in consumers’ perceptions of the relationship between art and business. At the lab, I collected data from more than 1,000 potential consumers, which supported my theoretical hypothesis about the impact of art on consumers’ perception of luxury objects. The experiments are the quantitative part of an international collaboration with Professor Elena Cedrola (Macerata Universiy, Italy) and Professor Geneviève Cohen-Cheminet (Paris IV Sorbonne). The
results have been turned into an international conference presentation, scholarly articles, and a book will soon be delivered.”

“My research explores social influence dynamics, with a particular interest in how the digital landscape has changed the way consumers think, feel and behave. In one experiment conducted at the lab, I asked participants to share news about a product on Facebook or on LinkedIn. Sharing information with someone on Facebook increased feelings of proximity compared to sharing on the less personal platform LinkedIn. Overall, this research suggests that the medium is a
factor that changes perceptions of closeness. I would like to thank the entire lab team for their great help with this project.”

“My research examines how individuals’ verbal and non-verbal communications affect others’ as well as their own psychological experiences and behaviour. In one of my experiments, participants engaged in sarcastic or sincere conversations. In another, participants acted as customer service employees and adopted various facial expressions and gestures. The lab gives me the opportunity to explore how experiences like these predict individuals’ perceptions,
cognition and behaviour.”
