17、ssist in the future study of empathy(同感，共鸣)The work could also help explain if and how computer games might cause children to imitate what they see on screen.Previous studies have already shown contagious yawning in chimpanzeesstimulated by videorecorded footage of yawns.“We wanted to expand on that
18、，” explained Matthew Campbell，a researcher from Emory Universitys Yerkes National Primate Research Center and lead author of the study.“Were interested in using cartoons for presenting stimuli to animals, because we can control all the features of what we show them，” he continued.Although Dr Campbel
