I am interested in long term negative physiological effects that some students experience following overstudying.
- What is the scientific basis for overstudying?
- Is over studying correlated with long term decreases of cognitive ability?
For example Jacobs and Dodd did a study on college student burnout:
They also cite some of the literature on stress in college students:
You've actually stated 2 questions in one. The second one is answered by Jeromy, the burnout or burnout-like states are the consequence of any overworking. I would also add the health problems, but those are not particularly on topic.
When it comes to the reasons, the learning can become the addiction, as most of the things you do. It can become obsession. There are people who are collecting knowledge, and want to have as much facts as possible in their heads, such as the other are collecting the coins or stamps or anything else.
I personally know many people, which, during their studies, have spent most of their time in the library, while their effects were not better as those of their collegues, who have spent not as much as the half of that time learning. That people were simply like ill when they weren't learning, they couldn't find their place. Many of them are now internet-addicted or have alcohol problem. It seems to be the neurotype, that easily becomes obsessed about something (therefore, extremally vulnerable to addictions).
