People who were asked to reflect on their many past successes or a specific failure scored roughly 10% better on tests of mathematical ability, as well as verbal, spatial, and abstract reasoning, than those who reflected on either many past failures or a single specific success.
This test, which relies on abstract spatial thinking, will now account for about two-thirds of the score, while the Otis-Lennon School Ability Test (OLSAT) will be about a third.
