We’ve all heard or engaged in this sort of thing: “Hi, buddy! Who’s a good boy?Youare!!!” But why do people talk to dogs as though they are babies? Perhaps some really do consider our pets to be like kids. However, researchers have just published apapershowing that dogs of all ages pay more attention to people who speak to them in a pet-directed speech versus a normal “adult” voice.Pet-directed speech is similar to how we talk to babies, which is called infant-directed speech. Both speech patterns involve talking in slow, high-pitched voices, repeating words, and sounding more positive and happier than when speaking with other adults. Infant-directed speech serves a specificpurpose: It helps babies learn language and creates a bond between babies and caregivers. It also helps babies pay attention like pet-directed speech and dogs.A recentstudy, however, directly contradicts with the previous study. It said that adult dogs clearly paid more attention to pet-directed speech, while puppies responded similarly to all human voices. The differences between the two studies include the fact that the previous study had a small sample size and recorded women speaking to pictures of dogs rather than actual living animals. The recent study had nine women speak directly to a dog, a baby, and an adult, and recorded their speech, instead.1.What did the researchers find according to the passage?A) Dogs pay more attention to pet-directed speech.B) Adult dogs prefer a normal adult voice.C) Dogs like to listen to sweet soft voices.D) Dogs are considered to be like kids.2.How does the infant-directed speech differ from pet-directed speech?A) It can draw attention more easily than pet-directed speech.B) It helps babies learn language and creates a bond.C) It involves high-pitched voices and repeating words.D) It sounds positive and funny when talking to babies.3.What advantage does the recent study have over the previous one?A) It studies both baby and adult voice.B) It studies both puppies and adult dogs.C) It has women talk to actual living animals.D) It has a smaller but more specific sample size.
