How identical twins influence each other’s self-perception

Whenever people learn together with others, they draw comparisons. Usually, a contrast effect occurs that immediately affects one's perception of one-s own academic abilities. If others perform better, one assesses one's own abilities as worse. If others perform less well, one perceives oneself as more talented and capable. These contrast effects have been confirmed repeatedly in various studies. Now researchers at the Hector Research Institute of Education Sciences and Psychology at the University of Tübingen have found a significant exception. In the case of identical twins, the comparison effect becomes a mirror effect.
