Has anyone ever done a study of the effect of grading on brain function? That is, has anyone does a study in which someone has their head wired to various devices while they grade, and then the images of brain function from the start of grading to the end of grading are compared to see what brain sectors are damaged? Is the damage temporary or permanent? Does the degree of damage correlate with how the students did on the exam or homework assignment? Is it safe to operate a motor vehicle after grading?
The effects of grading somehow feel different than other repetitive activities. Some of my research activities involve fairly tedious and repetitive tasks, but that type of thing doesn't feel as brain damaging as grading. I think brain scans would show different results for grading vs. other tedious activities, but perhaps I am not thinking clearly after grading tonight.
