　　What's your earliest childhood memory? Can you remember learning to walk? Or talk? The first time you 51 thunder or watched a television program? Adults seldom 52 events much earlier than the year or so before entering school, just as children younger than three or four 53 retain any specific, personal experiences. A variety of explanations have been 54 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 55 about the age of　two. But the most popular theory 56 that, since adults do not think like children, they cannot　 57 childhood memories. Adults think in words, and their life memories are like stories or 58—one event follows 59 as in a novel or film. But when they search through their mental 60 for　early childhood memories to add to this verbal life story, they don't find any that fits the 61 . 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 62 for childhood amnesia. She argues that there simply 63 any early childhood memories to recall. According to Dr. Simms, children need to learn to use 64 spoken description of their personal experiences in order to turn their own short-term, quickly 65 impressions of them into long-term memories. In other 66 , children have to talk about their experiences and hear others talk about 67 --Mother talking about the afternoon 68 looking for seashells at the beach or Dad asking them about their day at Ocean Park. Without this 69 reinforcement, says Dr. Simms, children cannot form 70 memories of their personal experiences.
