The goal of the Behavioral Economics Research Group at SWPS University of Social Sciences and Humanities is to advance current knowledge about human behavioral and cognitive processes and their underlying neural mechanisms, in the economic context. 

Our group is open to conducting collaborative projects. We invite Polish and international researchers to participate at all levels, from basic to advanced research activities. We set to accomplish our goals by exploring and collaboratively discussing potential topics of interest, obtaining funding, conducting research, and ultimately publishing and presenting the results of our research.

We cover all aspects of decision making, from behavioral, cognitive, to neuroeconomic approaches. Our recent research agenda includes research on intertemporal risky decision making and neurobehavioral aspects of effort-based reward valuation.

Current Research

In our ongoing work, we investigate how people make decisions when future is uncertain. In other words, we describe human decision-making process, in situations when choices pertain to delayed lotteries, i.e. delayed and risky gains and losses.

Our second line of current research is related to effort-based decision making. Here, we aim to determine how different types of effort impact reward valuation in choice behavior.
