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" (儿童失忆症). 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】______ child- hood 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 anything, at fits the【C11】______ . It's like trying to find a Chinese word in an English Dictionary.

Now psychologist Annette Simmons 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】______ inpressions 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.
