About

Mary Hegarty is a pioneering cognitive scientist whose research illuminates the intricate relationship between spatial thinking, reasoning, and human cognition. Her foundational work has defined the field of spatial cognition, particularly through studies on individual differences in spatial ability, the role of gestures in thinking, and how people mentally represent and navigate physical environments. Hegarty is best known for her influential contributions to understanding the cognitive processes underlying diagrammatic reasoning and the use of external representations, such as maps and graphs, in problem-solving. Her research, which has garnered thousands of citations, demonstrates that spatial skills are not fixed but can be enhanced through training, with profound implications for education in STEM fields. Notably, her widely cited work on the "mental rotation" and "spatial visualization" tasks has become a benchmark in cognitive psychology. Hegarty’s recent exploration of navigation strategies in robot teams (2024) extends her legacy into human-robot interaction, showcasing her enduring impact on how we think about thinking in space.
