最新研究顯示，孩子們可以回憶起自己一歲半發(fā)生的事卻總是忘記4到7歲時的事兒,。
此前人們認(rèn)為4歲以下的孩子因語言和認(rèn)知能力有限,，而無法擁有持久記憶,，并以此來解釋為何大部分成年人無法記起自己幼年時發(fā)生的事情。
但是加拿大紐芬蘭紀(jì)念大學(xué)的研究人員發(fā)現(xiàn),，孩童在4歲時也可想起幼時記憶,，但過了這段時間便會忘記。
著手于研究的心理學(xué)教授卡蘿爾-皮特森稱,，她的團(tuán)隊發(fā)現(xiàn)很小的孩子也有可供分享的記憶,。 “但是到10歲的時候,，他們的早期記憶似乎被凍結(jié)了，”她說道,。
皮特森的團(tuán)隊調(diào)查了140名4到13歲的兒童,，讓他們描述出3個最早的記憶。
出乎意料地,，年齡最小的孩子可以想起自己1歲半時發(fā)生的事,。同時爸爸媽媽也在場，以驗證孩子所說是否屬實,。
小組在兩年后重新調(diào)查了這些孩子,，并讓他們再次回憶最早發(fā)生的事。
研究人員發(fā)現(xiàn),，即使有詳盡的提示,，那些曾被調(diào)查、如今已是4到7歲的孩子已經(jīng)記不起來“最早”發(fā)生的事了,。但是,，10到13歲的孩子中有1/3的人可以重拾之前的回憶。
研究結(jié)果顯示,，穩(wěn)定,、“長達(dá)一生”的記憶往往形成于10歲或更晚。而10歲之前的記憶更脆弱且易于消退,。而這個刊登于《兒童發(fā)展》雜志的研究表明,，我們的“心理兒童期”開始得遠(yuǎn)比我們之前認(rèn)為的晚。（生物谷Bioon.com）

Infantile Amnesia Across the Years: A 2-Year Follow-up of Children’s Earliest Memories
Carole Peterson, Kelly L. Warren, Megan M. Short
Although infantile amnesia has been investigated for many years in adults, only recently has it been investigated in children. This study was a 2-year follow-up and extension of an earlier study. Children (4–13 years old) were asked initially and 2 years later for their earliest 3 memories. At follow-up, their age at the time of these memories shifted to several months later, with younger children unlikely to provide the same memories. Moreover, when given cues about memories recalled 2 years previously, many were still not recalled. In contrast, older children were more likely to recall the same memories, and cues to former memories were successful. Thus, older children were becoming consistent in terms of recalling very early memories.
