A bulk of research shows that when people are put in situations where they are expected to fail, their performance does plummet. They turn into different people. Their head literally shuts down, and they end up confirming the expectations. When they’re expected to win, their performance shoots back up. Same person, difference expectations.
In recent years, this phenomenon has been studied in a variety of high-stakes testing situations. One area that has received a lot of attention is in the domain of mental rotation. Out of all the gender differences in cognition that have been reported in psychological literature, 3D mental rotation ability takes the cake. While it’s true that there’s more variability within each gender than across genders, the differences on average between males and females on mental rotation tasks are notably large, in some cases as much as a full standard deviation.
