What is your earliest childhood memory? Can you remember learning to walk? Or talk? The first time you heard thunder or watched a television program? Adults seldom　1　events much earlier than the year or so before entering school,　2　children younger than three or four　3　retain any specific, personal experiences.

A variety of explanations have been　4　by psychologists for this "childhood a mnesia" (儿童失忆症). One argues that the hippocampus, the region of the brain which is　5　for forming memories, does not mature until about the age of two. But the most popular theory　6　that, since adults don’t think like children, they cannot　7　childhood memories. Adults think in words, and their life memories are like stories or　8　―one event follows　9　as in a novel or film. But when they search through their mental　10　for early childhood memories to add to this verbal life story, they don’t find any that fit the　11　. 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　12　for childhood amnesia. She argues that there simply　13　any early childhood memories to recall. According to Dr Simms, children need to learn to use someone else’s spoken description of their personal　14　in order to turn their own short term, quickly forgotten　15　of them into long term memories. In other　16　, children have to talk about their experiences and hear others talk about　17　― Mother talking about the afternoon　18　looking for seashells at the beach or Dad asking them about their day at Ocean Park. Without this　19　reinforcement, says Dr Simms, children cannot form　20　memories of their personal experiences.
