When researchers asked hundreds of people to watch other people shake boxes, it took just seconds for almost all of them to figure out what the shaking was for. The deceptively simple work by perception researchers is the first to demonstrate that people can tell what others are trying to learn just by watching their actions. The study reveals a key yet neglected aspect of human cognition, and one with implications for artificial intelligence. ‘Just by looking at how someone’s body is moving, you can tell what they are trying to learn about their environment,’ said author Chaz Firestone, an assistant professor of psychological and brain sciences who investigates how vision and thought interact. ‘We do this all the time, but there has been very little research on it.’
