Dr Amanda Rotella

Assistant Professor

Department: Psychology

I am an interdisciplinary researcher broadly interested in human social competition. I'm particularly interested in how socio-ecological factors shape competitive strategies (e.g., inequality, population density, reputation), and how, in-turn, competition influences cooperation, moral behaviours, and fertility decisions.

Before joining Northumbria University as an Assistant Professor in 2022, I was a Lecturer in social and health psychology at Kingston University, London. I also worked as as postdoctoral researcher at the University of Waterloo with Dr Igor Grossmann on a variety of topics, including cultural change, forecasting, and wise reasoning. I previously completed my PhD in 2020 at the University of Guelph, advised by Dr Pat Barclay, investigating when and why people make cooperative decisions.  

Amanda Rotella

Broadly, I am an interdisciplinary researcher interested in how social, situational, and ecological factors shape human social competition (i.e., how, when, and why we compete), and, in-turn, how competition influences people's behaviours and decisions. I am interested in a variety of topics, including cooperation, cultural change, inequality, morality, reputation, social signals, and wise reasoning.
