Babies are not just passing idle time when they stare goggle-eyed at the television—they are actually learning about the world, U.S. researchers said. Parents may want t limit what their babies see on television , based on the study, said Donna Mumme, assistant professor of psychology at Tufts University in Boston, who led the research. “Children as young as 12 months are making decisions based n the emotional(情感的)reactions of adults around them,” Mumme said in a statement. “It turns out they can also use emotional information they pick up from television. This means that adults might want to think twice before they speak in a loud and harsh voice or let a baby see television programs meant for information about the world. A mother urging her baby to eat some “yummy” soup on a brother crying in fear when a dog approaches can influence a baby’s reaction. Mumme’s team tested babies to determine. If television has the same influence, showing actors reacting on a videotape to objects such as red spiral letter holder, a blue humpy ball, and a yellow garden hose attachment. Babies aged 10 months or 12 months were later given the same objects to play with. Ten-month-olds did not seem to e influenced by the video buy the 1-year-olds were. When the actors acted neutrally or positively to an object, the babies happily played with them. But if the actor had seemed afraid or disgusted, the babies would avoid the object.72．Psychology is the study of .
