Question

Your high school is proposing moving to a system in which grades are no longer given or used to evaluate student progress.

Define each of the following concepts and state how each might either positively or negatively change student behavior under such a system.

a. Arousal Theory

b. James-Lange Theory

Not asking for too much, just a simple explanation how these theories relate to the situation? I can't figure it out

Also sorry for posting Psychology question here, but nobody is online in that section
