Our lab, led by Andrew Perfors, is part of the Complex Human Data Hub at the Melbourne School of Psychological Sciences. Our research focuses on quantitative approaches to higher-order cognition: categorisation, concepts, language acquisition and evolution, decision-making, and social learning and transmission. We use mathematical and computational models to understand the why and the what within these topics. What goals are human learners and reasoners trying to achieve in particular situations? What constraints (cognitive, informational, environmental) do they operate under? How do these factors shape their behaviour?
