Cohort effect refers to how a group of people who have experienced the same event or have similar characteristics can differ from other groups because of their shared experience. The teenagers in this scenario belong to a different cohort and have had more exposure to video games, which could explain their better performance in imagining the rotation of objects in space. The seniors, on the other hand, belong to a different cohort with different experiences and hence might not perform as well in this task.
