"The thinking cap 2.0": preliminary study on fostering growth mindset of children by means of electroencephalography and perceived magic using artifacts from fictional sci-fi universes

Interventions aimed at promoting a growth mindset in children range from teaching about the brain's ability to change to playing computer games. In this work, we explore a novel approach to foster a growth mindset by means of interaction with a "magic hat" system which consists of using objects from sci-fi and pop-cultural references like Avengers or Star Wars. The artifacts are "enhanced" with embedded Electroencephalography (EEG) electrodes. In an initialization phase, the "magic hat" uses established Brain-Computer Interface algorithms to recognize certain mental processes of the child and the child is then able to use their brain signals to control a robot. We report on an experiment that validates the system with children who were asked to solve math problems. We evaluated their mindset before and after use of the system. In comparison with a control group, the children who used the system self-reported having a stronger growth mindset.
