Annotations:

• Talking with your hands can trigger mental images that help solve complex problems relating to spatial visualization, an important skill for both students and professionals, according to new research
• "Hand gestures are spontaneous and don't need to be taught, but they can improve spatial visualization," said psychologist Mingyuan Chu, PhD, who conducted the research
• Hand gestures may improve spatial visualization by helping a person keep track of an object in the mind as it is rotated to a new position. Since our hands are used so much in daily life to manipulate objects, gestures also may provide additional feedback and visual cues by simulating how an object would move if the hand were holding it,
• Students in a physics class could be encouraged to use hand gestures to help understand invisible forces such as magnetic fields. Art students could talk with their hands in a still-life class to picture a bowl of fruit or a nude model from a different angle to create a more vivid painting that creates the illusion of three dimensions on a flat canvas.
