Humans interact with each other to share information and make decisions. Our lab investigates the cognitive and neurobiological basis of interactive decision making. We use behavioural psychological testing, functional and structural brain imaging and psychopharmacology techniques to understand human interactive behaviour.
Contradictory maxims such as “two heads are better than one” and “too many cooks spoil the broth” raise the question WHY people engage in collective decisions. We propose that an overlooked and very important reason to join collectives is sharing responsibility for decision outcomes. Sharing responsibility with others protects individuals from possible negative consequences of […]
We live in the age of persuasion. From the outcomes of political campaigns to our stand on issues such as global warming, immigration crisis and taxation, the fate of the most critical issues in our public life depends on persuaders working to influence public opinion. The research on social influence has been dominated by the motivation to understand the mind of the targets of influence (e.g. consumers, voters) in order to exert even more influence on them. Far less is known about the cognitive and neurobiological underpinnings of the source of the influenc
What is the cognitive, computational and psychological basis of success and failure of collective decision making? Joaquin Navajas employs computational modelling and behavioural psychology to address this problem. Our lab has a long standing collaboration with the Gatsby Computational Neuroscience Unit in developing the math of interactive decision making.
