behavioural research lab


XLAB – Behavioural Research Lab is a laboratory for exploring decision-making and economic, political, and social behaviour. It is located at the Lisbon School of Economics and Management (ISEG), ULisboa and it is supported by the research consortium PASSDA.

Our goal is to collect data and support research in social sciences, creating knowledge for the development of public policies that can shape the lives of citizens and businesses. We perform focus groups, laboratory experiments, and surveys.

Along the way we bring together researchers, students, and the wider community. We provide students with an opportunity to enrich their academic experience and to inform their career paths. And we offer all participants an opportunity actively contribute to the process of knowledge creation.

Resources: We have two lab rooms located on the second floor of the building Francesinhas 2 at ISEG. Lab 1 features 20 workstations equipped with the most widely-used software for developing and conducting experiments. Lab 2 has eye tracking technology, a BIOPAC system for psycho-physiological measurements, a one-way observation mirror, and space for meetings and focus groups.
