Well that looks like the behavior of any person with a strong passion and focus for his work. There are plenty of these around! I guess it would be more common in any field of work were people already have dedicated a significant part of their life to it, and where it is almost a prerequisite. Being a mathematician selects and cultivates people able to ...

I assume that the group that spends 100% of their time studying real analysis and 0% of their time doing n-back training will do best in any subsequent real analysis course. Cognitive skill acquisition does not generalise all that much (for a review see VanLehn, 1996). Transfer is often limited. I'm sceptical of any claims that short term training can lead ...

There's a very small percent of people who enjoy the adrenaline of mental exhaustion. While that signals most people to stop, there are people who will continue exhausting themselves. This isn't physiologically healthy. You need to recognize when you're worn out and rest. Don't get hyper-focused on your problem.

I would say it is highly unlikely. The report that you reference is the savant Daniel Tammet who has performed many impressive mental feats, including holding the European record for most recited digits of pi. He has been popularized in the media in such documentaries as "Brain Man". He claims that he is able to accomplish such mathematical feats because of ...

I don't know of research that answers this question directly, but I'm going to guess the answer is no, it wouldn't help, based on the following reasoning. First, people tend to learn math less well when superfluous visual richness is added. I think adding color to numbers counts as superfluous visual richness. Brown, M. C., McNeil, N. M., & ...

I imagine this question is tricky for students for a several reasons. Question wording: The question may suggest to the student that it is possible to differentiate $x!$. Or they may assume from the wording that some meaning is meant where it is possible to differentiate. For example, alternatively, you could ask a set of questions, one for each ...

If you define mental disorder as any behavior not applying to (more or less arbitrary) social norms, then yes, the activity you describe would probably be considered mental disorder. However, the same would apply for example to: homosexualism most hobbies asceticism and religious devotion playing and listening to music The last may seem odd, but Plato ...

If you pose the question only to students who have a perfect knowledge of high school calculus, without any knowledge gaps, then they should all give the correct answer. The "problem" is, that you can graduate from high school without having understood all the details about differentiation. Most students don't finish high school with the best mark in maths, ...

Yes, you can train your memory to be better at certain tasks, such as remembering numbers. For example Ericcson et. al. (1980) describe a university student who practiced memorizing numbers several times per week for twenty months and could then memorize and recall more than 70 digits reliably. I would not recommend such however if you are looking for ...

Retaining a large number Can you hold the number 7859385 in your head for an extended period without the image of the number becoming distorted at any point? Long term memory of a single long number: Obviously a large proportion of people remember a few phone numbers that are at least as long as the number you mention. So for long term recall there are ...
