What"s your earliest childhood memory Can you remember learning to walk Or talk The first time you 【C1】______ thunder or watched a television program Adults seldom【C2】______ events much earlier than the year or so before entering school, just as children younger than three or four【C3】______ retain any specific, personal experiences. A variety of explanations have been【C4】______ by psychologists for this "childhood amnesia". One argues that the hippocampus, the region of the brain which is responsible for forming memories, does not mature【C5】______about the age of two. But the most popular theory 【C6】______ that, since adults do not think like children, they cannot【C7】______ childhood memories. Adults think in words, and their life memories are like stories or【C8】______— one event follows 【C9】______—as in a novel or film. But when they search through their mental【C10】______for early childhood memories to add to this verbal life story, they don"t find any that fits the【C11】______ . It"s like trying to find a Chinese word in an English dictionary. Now psychologist Annette Simms of the New York State University offers a new【C12】______for childhood amnesia. She argues that there simply【C13】______any early childhood memories to recall. According to Dr. Simms, children need to learn to use【C14】______spoken description of their personal experiences in order to turn their own short-term, quickly【C15】______ impressions of them into long-term memories. In other【C16】______ , children have to talk about their experiences and hear others talk about【C17】______—Mother talking about the afternoon 【C18】______looking for seashells at the beach or Dad asking them about their day at Ocean park. Without this 【C19】______reinforcement, says Dr. Simms, children cannot form 【C20】______memories of their personal experiences. 【C20】
