What's 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 {{U}}(1) {{/U}} events much earlier than the year or so before entering school, {{U}}(2) {{/U}}children younger than three or four{{U}} (3) {{/U}}retain any specific, personal experiences.
A variety of explanations have been{{U}} (4) {{/U}}by psychologists for this "childhood amnesia". One argues that the hippo-campus; the region of the brain which is{{U}} (5) {{/U}}for forming memories, does not mature until about the age of two. But the most popular theory {{U}}(6) {{/U}}that, since adults don't think like children, they cannot{{U}} (7) {{/U}}childhood memories. Adults think in words, and their life memories are like stories or{{U}} (8) {{/U}}one event follows{{U}} (9) {{/U}} as in a novel or film. But when they search through their mental{{U}} (10) {{/U}}for early childhood memories to add to this verbal life story, they don't find any that fit the{{U}} (11) {{/U}}. 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{{U}} (12) {{/U}} for childhood amnesia. She argues that there simply aren't any early childhood memories to {{U}}(13) {{/U}}. According to Dr. Simms, children need to learn to use someone else's spoken description of their personal{{U}} (14) {{/U}}in order to turn their own short-term, quickly forgotten {{U}}(15) {{/U}} of them into long-term memories. In other{{U}} (16) {{/U}}, children have to talk about their experiences and hear others talk about{{U}} (17) {{/U}}--Mother talking about the afternoon{{U}} (18) {{/U}} looking for seashells at the beach or Dad asking them about their day at Ocean Park. Without this{{U}} (19) {{/U}}reinforcement, says Dr. Simms, children cannot form{{U}} (20) {{/U}}memories of their personal experiences.
