This study explores how scientific concepts, such as the specific ways that neuroscientists partition the brain into distinct regions, shape scientific investigation. One hundred fifty six undergraduate psychology students completed a science learning task in which they explored the functions of a fictional brain segment by conducting neuroimaging and lesioning experiments on it. We investigated how the partitioning of the segment into regions influenced participants' experimental choices and learning outcomes. We found that participants preferred to explore borders between the regions and overexplored small regions. Accordingly, participants were more successful in discovering the functionally relevant signals when these were located close to the conceptual boundaries. Finally, participants tended to associate a signal with locations within its region rather than locations that straddled region boundaries. This study contributes to understanding how concepts shape neuroscientific investigation.
