Researchers at Temple University’s Language Learning Lab found that children are less likely to learn a new words when a phone call interrupts the child’s conversation with their parent. In their experiment, researchers asked parents to teach their child two words, but answer a cell phone call partway through teaching one of the words. The team’s analysis showed that when parent-child conversations were interrupted, children did not learn the new word.
