The study showed, after a personality test,  that people identified with a house that fit our character.

Griffendors were the most extraverted, Hufflepuffs more agreeable, Ravenclaws sought more intellectual challenge, and Slytherins reported more of the “Dark Triad” personality traits: narcissism, Machiavellianism and psychopathy.

Standardized tests show which students have well developed problem solving and critical thinking skills.

However, the best students on average have the worst standardized test scores.

A study of 182 students revealed something interesting. It showed that the number of books at home and studying a second foreign language are good predictors of student intellectual ability.

6-7-Year-old children show improvements for test after having a drink of water.

Little research has examined the effect of water consumption on cognition in children. We examined whether drinking water improves performance from baseline to test in twenty-three 6-7-year-old children. There were significant interactions between time of test and water group (water/no water), with improvements in the water group on thirst and happiness ratings, visual attention and visual search, but not visual memory or visuomotor performance. These results indicate that even under conditions of mild dehydration, not as a result of exercise, intentional water deprivation or heat exposure, children’s cognitive performance can be improved by having a drink of water.
