Fourth-grader Jaden Darnell has an Xbox 360 and a PlayStation 3. Like many other kids, he also plays games on his phone. At times, he says, it can be hard to tear himself away from a device (设备), especially when he’s playing NBA General Manager.
What makes some video games so attractive? Raph Koster, an expert on game design, says game makers employ a great deal of knowledge about what keeps people playing. He says that whether they know it or not, players like getting feedback (反馈) that they can see or hear. The game Peggle, for example, plays the song “Ode to Joy” every time you succeed at beating a level. “It gives you this amazing amount of celebration,” says Koster.
Game makers also know that once players have put in the time and effort to achieve a goal, they don’t like to give up. So some games are easy at first and become more challenging (挑战*的). At that point, the players may be offered a resource (资源) that makes winning easier. “The game creates a problem that it offers to solve for you in exchange for cash,” explains Ian Bogost, a professor who studies video games at t
he Georgia Institute of Technology. When players are connected to the Internet, developers can observe what they do. By recording players’ choices, game companies can find out what keeps people interested in and what makes them most likely to buy things.
Besides game developers, scientists are also paying attention to the power of games. Adam Gazzaley, a scientist at the University of California, has developed games that improve attention and memory in older adults. Now Gazzaley and his team are designing brain-building games for kids. “We think that how video games really pull you in and demand your attention can be used to help improve how the brain process (处理) information,” he says. To test the games’ effects on the mind, Gazzaley records brain activity while people play. He says that one day, doctors might advise patients to play video games to improve their intelligence.
