sure we have all heard about the ill-effects of staying up late, we have research finding summarised and the super-summarised by journalists(much to the dislike of scientists, i may add). But as some studies have proven, we learn better with tighter feedback loops. Just tried out lumosity exercises on response inhibition. clearly lower scores. my ability to inhibit responses is pretty down. Interestingly, when the task involved Quantitative aptitude, there was no significant change in response inhibition. More kudos to the pros of practice.
