I'm an extreme introvert and its detriments are plaguing my life. I think a lot and deeply before writing, it wastes a ton of time. I also think more before I speak, it doesn't look attractive like I want it to look. I perform poorly on tests because I dwell upon them deeply, and it takes a lot of time to finish them. I wouldn't become an extrovert because it has detriments too. However, I am curious, is it possible to switch between introversion and extroversion through certain meditative techniques?
The higher extroversion is, the higher the reward sensitivity of an individual. Extroverts could probably be able to focus on their emotions and reach a state of introversion while introverts could probably be able to focus on certain circumstances and try to feel the reward, to increase reward sensitivity and perhaps reach a state of extroversion. If either of them get this kind of training, is it possible for them to switch between their two states?
