Cognitive Science · Development · Representation
Lauren S. Aulet
I study how minds learn to represent the world.
I am a cognitive scientist studying learning, representation, and reasoning. My work combines behavioral experiments, developmental cognitive neuroscience, and computational modeling to understand how abstract concepts emerge across development and experience.
About
Learning, representation, and reasoning across development.
I am an Assistant Professor in the Department of Psychological and Brain Sciences at the University of Massachusetts Amherst, where I direct the Cognitive and Neural Development Laboratory. My research asks how humans develop abstract concepts, with a focus on number, space, symbols, and reasoning.
A lot of my work is about measurement: how do we study thoughts and representations that people cannot simply report? This question comes up with young children, who often know more than they can explain, and with computational models, where we can test how different learning experiences change what a system represents.
I am also interested in what cognitive science can bring to the study of AI systems and the people who use them: how to evaluate reasoning, explanation, learning, and overreliance when the process behind an answer is not directly visible.
Research
How can we infer hidden representations and reasoning processes from behavior?
Learning and representation
Computational modeling
Cognitive measurement
My research is organized around connected questions: how people perceive structure in the world, how children build abstract concepts, and how learning changes representations. Across these domains, I use behavioral experiments, developmental neuroimaging, and computational modeling to study cognitive processes that cannot be measured by self-report alone.
