Associations between early deprivation and memory functioning were examined in 9- to 11-year-old children. Children who had experienced prolonged institutional care prior to adoption were compared to children who were adopted early from foster care and children reared in birth families. Measures included the Paired Associates Learning task from the Cambridge Neuropsychological Test and Automated Battery (CANTAB) and a continuous recognition memory task during which ERPs were also recorded. Children who experienced prolonged institutionalization showed deficits in both behavioral memory measures as well as an attenuated P300 parietal memory effect. Results implicate memory function as one of the domains that may be negatively influenced by early deprivation in the form of institutional care.
研究人员检测了 9 至 11 岁儿童早期剥夺与记忆功能之间的关系。研究人员将经历过长期机构照料后被收养的儿童与那些从寄养家庭中被早期收养的儿童和在亲生家庭中长大的儿童进行了比较。研究采用了剑桥神经心理学测试和自动化电池（CANTAB）中的配对联想学习任务以及连续识别记忆任务，在此过程中还记录了事件相关电位（ERP）。研究发现，经历过长期机构化的儿童在行为记忆测量和顶叶 P300 记忆效应减弱方面都存在缺陷。研究结果表明，记忆功能可能是受机构照料形式的早期剥夺负面影响的领域之一。
