 Interaction with the devices causes the children to develop advanced knowledge, genius-level intelligence and psionic abilities.Due to her psychic connection with Mimzy, Emma's development of her abilities is much stronger than her older brother's; she is the only one to display empathy, telepathy, levitation, and telekinesis (though Noah can also communicate with her once she has telepathically contacted him).Emma is also the only one who can use the "spinners", small rocks that when spun, telekinetically float and can produce a force-field.
